6BK11 NOS Ampeg Tube, N/A See 6C10

Sorry no more stock. Printed with the Ampeg logo on them. You can use the 6C10 in it's place. The 6BK11 was used in early Ampeg Jet J12D some Rockets and Reverberockets. The most critical stage for these was the tremelo, first tube in J12D, so you can get away with buying one of these and using a 6C10 for the other. Note: it will help your tremelo if you change out the capacitors in that circuit with fresh ones. Make sure to hold on to your old ones too.
