Bias Master™ - TAD, tube tester, with 4 probes

Question:
do you set the bias master up on a mesa boogie mark iii simul class the same as you would on a regular 4 tube amp? thanks. David.

Answer:
The Bias Master simply installs into the tube sockets of the amp and then the tubes are inserted into the probe sockets for any amp. It reads the current flowing from the cathode of the compatible tube types. If your amp disables certain tubes on different settings the meter will show no bias current for the disabled tube.
