The counsel from aniwolfe is the best possible.
By the way, if you do get it fixed, I strongly recommend that you follow my counsel presented here:

Recommendation for Repair Service for Dodd Audio Battery Preamp
My Dodd Audio Battery Preamp has developed static/hiss/vibration which is unlistenable.. Odd, but standard 6922 tubes sound soft while higher quality RAM 6922 sounds louder and worse. I need a service/repair business that is familiar with this unit. I am in Atlanta, and so I'd like service in GA or neighboring states of NC, SC, AL, TN or northern FL, if possible.
Thank you all in advance...
