Model 15 service information

[Bob the Tech]

Hi, I've got a Model 15 in the shop but the assemblies don't match the Model 15 manual I found on line at hifiengine. I can follow what's going on by tracking traces, but there are parts and circuits in the manual that are not in this unit, and there are quite a few parts with different values. Good news is I have a good channel to compare the bad channel to, but if anybody has a line on Model 15 manuals, I'd appreciate it.

Serial number on this unit is, I believe 14688.

Regards,

Bob

These amplifiers went through several updates while being produced, along with various service bulletins. I would go by what's in the amp over what you find in the service manual. Also try and find any service bulletins for your serial number.
The service bulletins will list the serial number range for any updates needed.

It was clear that my manual was not correct for this version of the amp. I did some google searching, which got me back to a 2015 thread on this forum, and a "gen 3" manual had been attached to that. So I found what I needed after all!

It's too bad Chris isn't around anymore. He had a site up with the complete manuals and bulletins for these along with the 16's and a few others. It was a big help when I restored my model 16.
