Magnificent Magnavox / Model 1SB115F

I'm trying to identify a 1960s console stereo. There are no manufacturers name anywhere just a label inside that says Model 1sb115F and RETMA232

Attached are pictures of all numbers on the AMP chassis. All I really need to know are the specs for replacing the capacitors. I can read the numbers off most of them but I just like to verify with a parts list or schematic.

The numbers on the AMP are 147AA 5 38 3 Stamped on the end of the chassis is 635134-10. I did not find a schematic for this in the downloads.

That's it!! The folks on this site are great. Does anyone have a schematic for this?

I need some help identifying and finding technical information for what I believe is a 1950's consolette record player with a Collaro High Fidelity RC54 record changer.  The only number stamped on the cabinet are 692473-2 and 37-amc-33. On the tube diagram is 590838. Thanks for your help.

Hi All

I'm new to vintage stereo repair although not vintage stereos except they weren't vintage when I was using them. :) Recently my wife bought me beautiful vintage stereo and I have been working to bring it back to it's original sound quality. I have read many forums and threads in preparation for this project. At this point, I've got if fully operational but with a few issues.

I began with replacing all the electrolytic capacitors, cleaned all the switches and pots and replaced the channel AF amp tubes and the left and right output tubes.

I get good volume from the right channel although a little distorted at the high end and low volume with a lot of distortion on the left channel.

Another more minor issue is that I don't get any sound from the mid-range or tweeters on either channel. I replaced the caps on them with the specified non-polarized replacement. I have bypassed the caps to make sure the speakers are good and have even tried driving them from a different amp source.

I was a technician for a short time 40 years ago but my profession took off in another direction. Now that I'm retired I back to where I started. Only trouble is, I don't know where to start trouble shooting this. I have the SAMs for the system and can still read the schematic. I just don't know what to look for or where. Any help would be appreciated.
