i have tried today by puting screen and plate together and feeding the plate with the tube reg output and swapping one 10K resistor on it.  and remove the feedbach resistor.

the voltage on the plate are now 220V  , the regulator are brighter than usual but it seems working .

the sound of the mini torri triode strapping is very relaxed with beautiful tones , perhaps not as clean as it was before . and a little less strong bass.     i will let it some times like that and return to the original setting to compare Wink

I would not have done that. Using a 6K6 tube brings down the bass a little bit.

i have done it just for fun , but at the end i prefer the penthod mode in this amp.   next step MKP cathode bypass capacitor ,  MKP 5OuF in the power supply  ;)

i have already made  1/2 12AU7 mode to have a little less gain and swap one coupling cap.  put a Vcap CUTF as the only cap in the signal , change all resistor with 2w and 5w Kiwame,  put off the volume pot and tone control.

i will never stoping say thank you to  the decware crew for all the hours of joy that this little amp gave me Grin
