Hello and have good year.

First please forgive my broken English but I am French.

I have an R88 amp with which I have a small problem.

I carried out all the Skunkie modifications and it is ok, it works very well in triode mode.

However, I have a lot of saturation in the sound when I raise the volume in the ultra linear position.

I have rewired all the wiring, exchanged all the tubes, but the problem persists.

I don't know where the problem could come from, do you have any idea?

THANKS

Michael
