[silencer eleven]

hey i have all new tubes for the z 28, i know that i need to bias the power tubes but do i have to bias both the pre amp tubes and recitifier tube. can i just throw these babies in till i can get the new power tubes biased?

thanks evan

To my knowledge you do not have to bias a rectifier tube. It is just converting voltage from AC to DC. As far as preamp tubes they should be plug and play operation.

what about pre-amp tubes

Sorry ..... Ya preamp tubes are just a plug and play deal. No biasing needed.
