Howdy everyone, I have loved my little PV Bravo for awhile (1991 Amp of the Year!) and wanted to make a version with a few changes;
1 some mods to put it closer to the Ultra/XXX family
2 no clean channel
3 variable bias
4 much more PS filtering with cheap 1"x1" snap in caps used instead of axials
5 no reverb (it feeds back over "5") but a level controlled FX loop from the JSX
6 a Presence/Resonance control, also from the JSX
The schematic is just the pre and power amp; the FX and Presence/Resonance will be on remote boards.
The PCB will etch to just 10"x5" single sided and includes a remote tube board with room for high powered RGB LEDs coming up through the tube sockets (it should look good!)
Thanks in advance for your help, I'll post clips and the complete PCB and BOM when I finish
