Need schematic

[JMT]

I'm working on a '66 Univox Bass Amp for harp. I've re-tubed it and replaced the speaker with a 15F150. My tech has gone through it and cleaned it up fixing some small problems. This is a cathode biased 2x6L6 amp with 2x12au7 in the preamp and a 12ax7 PI. MY tech has also improved the treble tone control to make it better for harp. I think that it sounds pretty good but a little sterile. I'd like to get it sounding a little more horn-like. I'm pretty sure I could get more help in tweaking if I had a schematic but Univox schematics are often hard to come by....apparently. I think the chassic is the same as a Univox U-1235 bass head. Any suggestions?
Thanks in advance,
Jay

Schematics

One of these will probably work for you.

Thanks, Steve! The U-1236 looks pretty close to me. Now...onward to the holy grail. LOL
All the best,
