Just an Update....
Posted by: Kernel86 on Thursday, January 24, 2019 - 12:04 CST
Yes we're still alive, in case anyone was wondering!

I just wanted to make a quick note that I do have quite a bit of service information available that (still) haven't been processed for the site. This includes a large collection of already scanned manuals and plenty that haven't yet been scanned. So if you're looking for a service manual for Sylvania stereo equipment, or even tvs from the '70s and earlier, give me a shout and I might be able to help you out!

*Some of these are listed via the old Service Manuals link on the left, but a lot of them aren't.

New speakers models
Posted by: Kernel86 on Wednesday, August 02, 2017 - 01:55 CDT
I've added a bunch of new speaker models which were missing.
Here's a list: AS-5WX, AS-6WX, AS-10W, AS-10AX, AS-10WX, AS-12WX, AS-12W, AS-15BT, AS-20BT, AS-25, AS-30, AS-42W, AS-80, AS-85B, AS-105W-1, AS-105W-2, AS-125W, AS-1706-1, AS-1708-1, AS-1710-1 and AS3712-1

There's a bit of information available for some of them, but for the most part I just have the release year and configuration. I've also updated the release dates for a bunch of the other models. The list should now be mostly complete with all models from the first AS8 in 1964 though the GTE 412 in 1976.

Pictures have been added for the AS-125W and AS-85B.

New Scanner
Posted by: Kernel86 on Saturday, March 28, 2015 - 21:06 CDT
I finally got an A3 size scanner which will really help with scanning in the collection of service manuals I have. The first batch I've been working on are several yearly service volumes and have just shy of 1000 pages scanned. Processing has just begun but hopefully I'll be able to start adding some new sections, models, and of course downloads shortly. Stay tuned!

New specs!
Posted by: Kernel86 on Friday, February 13, 2015 - 16:56 CST
Updated specs have been entered for the CR-2743W, CR-2472W, and CR-2741 receivers. The AS-D8WH globe speaker has been added with specs. Specs have also been updated for the AS-125W-1, AS-125A, AS-105W, AS-85W, AS-1712, AS1710, AS-1708, and AS-1705 speakers.

Added some pictures for the RQ-4747.

GTE 2300 & 2600 Added
Posted by: Kernel86 on Wednesday, January 02, 2013 - 18:41 CST
The GTE 2300 and 2600 model receivers have been added. There's still not a lot of information about these models, however, I have been able to confirm that the GTE 2300 is rated for 20wpc and the GTE 2600 is rated for 80wpc.

Tube Tester Settings
Posted by: Kernel86 on Saturday, August 18, 2012 - 13:39 CDT
I started adding a section for tube tester settings under Documentation. I will be entering updates from the Sylvania News Technical Sections, original roll charts, and other sources as they become available to me. Settings will be entered for all models, but primarily the Type 620, 220/219, and 140/139.

If you have any roll charts or third party update booklets for any Sylvania testers, I'm interested in hearing from you in hopes to make this as complete a database as possible!

Pair of Sylvania AS-225A's for Sale In Tennessee
Posted by: Kernel86 on Thursday, May 10, 2012 - 23:04 CDT
These have been sold.

If anyone is interested in a pair of Sylvania AS-225A speakers, now's your chance! These are not mine, however, I have been in contact with the seller and have agreed to post them here in hopes of helping find them a new home! If interested please use the contact information provided below.

Contact Information:

Phone: 615-485-5565


'A pair of AS-225A GTE Sylvania speakers up for sale in 85% plus great condition. They were re-foamed by me about 5 years ago and they sound beautiful. I am asking $600 for the set. The price is negotiable and all offers will be entertained, but I am not going to give them away. You may call me if you like. If interested I would prefer that the speakers were to be picked up from me in Nashville, TN because shipping them would require crating them and I don't have the materials. However, I would entertain crating and shipping them but it wouldn't be cheap.'

History Update and Ads
Posted by: Kernel86 on Sunday, February 12, 2012 - 21:49 CST
No not those kind of ads! I've posted about seven new ads to the downloads section.

The Company History page has received a lot of work and is nearing completion. It currently covers up to about 1974 and is based on what little information is available on the subject. The primary sources for this page are:
Newcomen Address: Sylvania during 50 years, 1901-1951 (The Newcomen Society) 1951
The History of GTE - The Evolution of One of America's Great Corporations (Thomas E. McCarthy) 1990

Company History Section
Posted by: Kernel86 on Sunday, February 05, 2012 - 08:48 CST
I added the beginnings of a history page. At the moment it just contains a list of company names, dates, and some logos. More details to be added!

Posted by: Kernel86 on Saturday, January 28, 2012 - 01:26 CST
I started adding some consoles. Models added for now are just the 1966 collections, however, most specifications and better descriptions still need to be added.

Category Updates
Posted by: Kernel86 on Thursday, January 26, 2012 - 22:02 CST
There has been some shuffling of information for the model pages with. Downloads available for specific models are now also linked from the individual model pages for easy access.

Minor Downtime
Posted by: Kernel86 on Monday, February 14, 2011 - 12:05 CST
Sorry for the brief approximately 2 hours of down time. The server was moved to a new home and there were some unforeseen problems which delayed bringing it back online.

Posted by: Kernel86 on Tuesday, December 07, 2010 - 10:31 CST
Just some testing, news to come!
Edited by: brivak on Saturday, December 11, 2010 - 21:48 CST

We're Still Here
Posted by: Kernel86 on Saturday, March 06, 2010 - 00:42 CST
Yes I'm still alive! Sorry I haven't made any real updates in awhile but hopefully that will be changing.

Picture Update
Posted by: Kernel86 on Friday, December 05, 2008 - 14:32 CST
It seems the pictures were offline for at least the past couple of weeks, not sure how long really. I've fixed the problem and they are now available again.

Server Trouble
Posted by: Kernel86 on Wednesday, October 29, 2008 - 20:21 CDT
I'm sorry to say we've experienced some server trouble and lost a hard drive.

Fortunately there was no data loss and I have restored the site on our old server for the time being.

Find some gear on Craigslist!
Posted by: Kernel86 on Friday, October 17, 2008 - 07:44 CDT
I added a new link to the right hand side of the page for Craigslist. This is actually a link to the stared items from Google Reader which just happen to be vintage Sylvania gear that need new homes! I'll do my best to keep it up to date by updating it a couple times a week for you.

Just on a side note these listing are across all 325 US Craigslist groups and not locale specific.

Some donations!
Posted by: Kernel86 on Monday, October 06, 2008 - 14:20 CDT
RayW of AK and MA has made a generous donation of gear to my collection and I just wanted to share my thanks here!

Here's a list of what I received:

Sylvania RS-5741 Receiver
Sylvania AS-5708 Speakers
Sylvania T-3703 Turntable (Garrard 6-300)
Sylvania ET-2750 8-Track Deck (BSR T-145)

Imaging system
Posted by: Kernel86 on Thursday, June 19, 2008 - 22:47 CDT
Some major tweaks have been made to the imaging system and it is now live on the current two categories.
Pictures have been posted for the following models:
GTE 2400


Site Updates
Posted by: Kernel86 on Thursday, June 19, 2008 - 12:05 CDT
I added a 'Go Back' link on the appropriate pages in the upper right hand corner of the content area.

I've also begun implementing the imgview based picture system. It is live now and more pictures will be posted shortly. If you have any comments please don't hesitate to let me know!

Some more Speakers
Posted by: Kernel86 on Tuesday, June 17, 2008 - 23:01 CDT
Thanks to rmaiers of MA for providing a brochure I've been able to add some specs on the following models:

A big thanks and everyone else enjoy them!

Service Manuals
Posted by: Kernel86 on Monday, June 16, 2008 - 18:42 CDT
I've added a very rough list of all the Sylvania Service Data I have available. It needs to be revamped so it is very messy as it stands now but it should suffice.

If you need anything off the list just shoot me an email. I can't make any promises as to a time frame I can get a specific manual scanned, but requested manuals will get priority. Eventually all the listed manuals will be available for direct download, possibly not the television manuals but I haven't decided on those yet.


New Server
Posted by: Kernel86 on Tuesday, June 10, 2008 - 04:27 CDT
The site has been moved to the new server. If you experience any problems such as choppy loading pages or errors please let me know!

Schedueled downtime
Posted by: Kernel86 on Thursday, April 24, 2008 - 14:56 CDT
The network this server is hosted on will be down tonight, April 24th, between 11pm and 1am (-6 GMT) for network maintenance. I apologize in advance for any inconvenience.

More speakers.
Posted by: Kernel86 on Saturday, March 29, 2008 - 02:01 CDT
I've just added about a dozen new speaker models. More to come yet, pictures soon I hope!

Progress...or something like it
Posted by: Kernel86 on Sunday, February 10, 2008 - 23:41 CST
I've added a few more receivers a some speakers to the database.

Work is progressing on the image system. However as this server lacks the needed software to process the uploaded images and would require downtime and software upgrades to do so, they won't be available until I upgrade to my new server. This should happen sometime this month if everything goes according to plan. In the meantime I am working off a test server and the image features will be ready by the time the new server is active.

More Receivers Added
Posted by: Kernel86 on Sunday, January 27, 2008 - 18:56 CST
There are now 16 receiver models available. Each has all the specifications I currently know for each unit.

Speaker & Receiver Categories are up!
Posted by: Kernel86 on Saturday, January 26, 2008 - 08:16 CST
As of now both the Speaker and Receiver categories are up and running. However this in no way means those sections are complete. Major parts currently lacking are pictures and a back navigation button/link somewhere, otherwise they are mostly the way they're going to stay.

There is currently one entry in both categories. I'll begin adding more throughout the coming week but there is still a load of work to do on the site and that will be my priority for the next couple of days.

If you happen to visit please let me know what you think! You can contact me via email (see my name) or as Kernel86 on the Monster Audio and AudioKarma forums.

Status Update
Posted by: Kernel86 on Wednesday, January 23, 2008 - 14:06 CST
Well most of the database designing is done. For the most part now it's a labor of completing the display interface and data entry page. And then lets not forget the loads of data that needs to be entered into the database.

The categories sections will come up first, I'll worry about the downloads later. There are two entries in the Receivers category right now that I've been using to work out the layout, feel free to check it out!

New Graphics!
Posted by: Kernel86 on Tuesday, January 22, 2008 - 20:57 CST
I've created a new style of graphics for my layout and given the dark nature I decided to call them 'Dim'. These are NOT to be the final style of this site but I figured I had to do something about that horrible orange and blue color scheme. I think these should do nicely until I figure out exactly what I'm going to for the site, but I do know it's gonna be something lighter! :-P
