Title: 1974 190L - need schematic
Post by: Bruce Clement on September 07, 2018, 11:55:52 am

There doesn't seem to be a lot of info on this model. I'd like to check a few things (bias, voltages, verify correctness, etc.). The only schematic I found is a PDF labeled "sentura II schematic," dated June 1, 1967 and has two schematics. The one with tremolo and reverb (like my amp) is labled "190L - Sentura II Sceptre Solarus 100S." Some things on that schematic don't match, so I'd like to find the correct one, for 1974.

Thanks!

(EDIT: This schematic I found is on the Fender Sunn Support page: https://support.fender.com/hc/en-us/articles/115002389226-SUNN-Schematics).

I might have a copy of that schematic at home. I'll check later tonight after work and let you know.

For some reason the search engine in the "Hello Username" frame can't find "190L". The SEARCH button above will find it however.

Look in this thread:   https://forum.sunnstillshines.online/sdp/index.php/topic,4772.0.html

Hopefully the attachments aren't corrupt.

Thanks for directing him to where he could find the schematic Loudthud. I had a 190B schematic which was likely the earlier one that you were not looking for Bruce Clement.
