Thanks man. Do I need to have it bias/set up to change any of the tubes?
6505+ problem?
I've had an 6505+ for about 9 months, love it. Recently though Channel 1 has had a popping sound, not real loud. Kinda sounds like when you have a cellphone to close. When I play you can't really hear it and Channel 2 has no such problem. Is this a preamp tube problem or something else? Thanks
