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

Could be a tube, or- a loose pin/socket.    Try swapping your tubes, between channels.     See if the noise follows.                 If you bought it new; the rest of the amp is covered for a two year period.

Thanks man. Do I need to have it bias/set up to change any of the tubes?

Not if you’re staying with the same output tubes.     There’s no bias adjustment for pre tubes.     Here's hoping it’s that easy (just a tube)!
