I wish I could use a meter, but I don't have jacks.
Tube Biasing Tools
Anyone have experience with TAD BiasMaster? Is there something else comparable to the TAD? My amp uses LEDs to set tube bias, one per tube. And there are not jacks to check bias with a meter. I'm looking for a way to track tube bias readings.
