Title: Supro 1605r can't find a schematic!
Post by: swingarm on January 04, 2021, 09:38:26 pm

Hi guys, I'm having a difficult time finding a schematic for this amp. I would be grateful if anyone that can, would help me out. I looked through the valco/supro schematics here but did not see it. Thanks very much!

What I found ;  same as the Gretsch G6162

http://www.oldfrets.com/Valco/Schematics.html (http://www.oldfrets.com/Valco/Schematics.html)

the 1605R is a current production 5 Watt utilizing a 6V6 in SE with 12AT7 reverb driver - that grestch 6162 is not even a close to a match, aside from being ≈55 years older.

respectfully,

If this is a new production reissue amp you're not likely to find a schematic in the wild. Probably need to contact Supro.

The 1605 would be nice to find and have a look at. I wanted to look it over after reading this.
