Guild t1-rvt guitar amp circa 64-65

Can anybody provide a better schematic than I have found so far in the net?  I'd like to be sure I have a better readable one, especially the power supply outputs to tube plates and cap and resistor values?  Appreciated.

Hello Johnboy,
How do you mean "output tyranny is bad" ?

Also, if someone might have a Guild T1 RVT on the repair bench, I'd love to get in touch.

Hello  Johnboy!

See the schematic:

https://elektrotanya.com/guild_thunder-t1rvt_sch.pdf/download.html

The the first capacitor after the rectifier tube is 50uF/450V, The 1.-2.-3.-4. capacitors belonging to point 40uF/450V, point 5 60uF/450V, then again 40uF/450V the essence can be seen in the attached drawing detail.(C-R-C supply)

Regards: Tony

Hi Tony,

I'm working on a T1-RVT, what capacitors did you use? The closest I can find are 500v 47uF, 450v 70/40/40uF and 350v 40/40/40/40uF. Those should be close enough right? Thanks!

Thanks
just replaced both can capacitors.  Now I've found the output tyranny is bad.

Replaced output transformer with a 15 watt Hammond push-pull transformer, a microphonic 6GW8 tube...and now it sounds great!
