Ok...Good...LOL...
I finally understand...
I will try to not kill myself with modifing amp !
As soon as I receive my parts, I will send picture...
I fing a vintage trimmer pot so, I will replace the new one.
I also need to find a vintage original Impedance Switch .
If I use The 240V insted of the 120V tap on the PT....Is I have something else to change to drop it at 50W???
