Re: Help with Atma-sphere MP3 and DC offset

Just to reiterate, it is not the Raytheons that are causing the problem per se; it is the fact that the two sections in whatever ones you are inserting are too far apart electrically for the balance circuitry to operate properly. To my recollection, the MP3 uses two sections in a single 6SN7 per channel for the circlotron output, so the sections within each tube need to be relatively well matched. Are they used tubes?
