I know its hard to do an over the internet diagnose for an amp. There is something wrong with my amp. There is some kind of mettalic sounding buzz when hitting certain low frequencies. I hae no idea whats wrong with it. I will probably take it to an amp tech if I cant figure it out.
 
Re: Amp troubles!!

Could be a microphonic preamp tube b79. The preamp tubes (small) in that C50 are tubes you can just pull straight out and swap around. If you have an extra preamp tube, try it in each position until you find you find the preamp tube that is giving you the issue. If you don't have any extra preamp tubes, try using the preamp tube that is closest to the power (bigger) tubes as a swap tube with the other positions. If you are going to have a tube amp, you will need to have extra tubes on hand for troubleshooting.
