I've added a scan of the the Sylvania ECG Semiconductors 1979 Master Replacement Guide. This can be used to convert Sylvania part numbers (and others) to ECG/NTE part numbers. It can also be used to cross reference ECG/NTE part numbers back to other manufacturers, if you're really bored that is. ;)
You can download directly it here: Sylvania ECG Semiconductors 1979 Master Replacement Guide ECG212J_NoOCRRaw.pdf
It's also available for online viewing at archive.org:
I've added service manuals for the AS-10 and AS-10-1 speakers along with the ones for the R14-2,-3 and T41-1,-2,-3 chassis and Garrard changers with the 11-18254-1,-2,-4,-5,-6 part numbers. These cover a lot of the 1965 console models.
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.
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.
