J M Fahey and Brymus:

Thanks for your comments and suggestions.  I'll definitely be looking at Apex for a transformer.  The toroids look promising and it should be fairly easy to mount one in the amp.  I'll start trying to sort out the reason for the transformer failure and any tips about that search would be welcome.

I believe the finals are 2SD-613E's which cross to an ECG377.  I don't know how this would compare to a TIP31 set.  Oh, and I've just recently learned of the chipamps and will look to building one soon. 

Again, thanks to both of you and best regards,
Strick

New guy here.  Trying to replace a dead power transformer in this SS Fender amp (Sidekick 35 Reverb).  The Sidekick series appears to have been built for a few years starting in the early '80s.  Fender says that no parts list is available but they did email a schematic.  Problem is that the schematic doesn't show the transformer secondary AC voltage or the DC voltage at the output of the bridge & caps.  The only identification on the dead transformer is "TCE66 086" and "30UC".  I could not find anything by searching on various combinations of this information.  I've Googled and Bing-ed and read forums and applied due diligence in my research to get this sorted. 

I found a schematic for a Fender Sidekick 35W Bass from the same amp series that indicates +/-31VDC at the DC test points after the rectifier "box".  I'm assuming that the box is a full-wave bridge rectifier and I've backed up from the 31 volts using the 1.414 factor.  That works out to about 22VAC input to the bridge.  48VCT (24-0-24) at 2A transformers seem to be more common but that would be nearly 34VDC after the bridge.  Is that too high? 

Does this sound like a reasonable way to try and get this thing going again?  Is the 31V guess based on the 35B a sound way to proceed?  Schematics from the 35R and 35B are attached.  Comments are welcome.

Thanks for your time,
