It is impossible to use 6L6 tubes with this amp, the little mids that I have now are then totally gone.
I have Emailed Voodoo amps but got no response. I have opened the amp and these are the mods I have noticed:
(These are located on Page 4 in PDF schematics)
C1 has been replaced with 1uF 50v cap
R1 has been replaced with 2.2K
C6 the 2,2nF that is suppose to be there alone now is put into a serial connection with a little circuit consisting of 470K resistor in parallel with a very small brown cap (I cant read the value)
C7 instead of 680nF now there is a serial connection of 47K resistor and 0.47uF 50v
R9 has been replaced with 4,7K
C19 has been replaced with 22uF
(These are located on Page 2 in PDF schematics)
V1 Mods:
-There is an added 22J (I guess that means 22pF) cap between pins 6 and 7 (which is V1B A. and V1B G.)
- 68K that is going from V1A G. to PAD 8 has been replaced with 820 Ohms
V2 Mods:
-There is an added 1uF cap between pin 3 (which is V2A K.) and middle pin
-Connection wire that is going from V2A A. to V5A G. has a hidden (shrinkwraped) resistor of unknown value added in serial.
-Connection wire going from pin 2 (which is V2A G.) to PAD 12 also has hidden (shrinkwraped) unknown resistor added in serial.
Following things I believe are not mods but just printing mistakes in schematics:
-PC Board 9078_3 next to PAD 8 says it’s connecting to V3B G. it should say V3A G.
-PC Board 9078_3 next to PAD 18 says it’s connecting to V4B G. it should say V4A G.
- Schematics says that V5B A. is connected to V4B A. via 100K. In reality V5B A. goes to PAD 22. (which does say next to that PAD) and it is V5A A. that is connected to that 100K line from V4B A.
Now can anybody PLEASE figure out which one of these mods is eating my mids
