Bias Master™ - TAD, tube tester, with 4 probes
Bias Master™ system BM4 Measures Bias current of the vacuum tubes in your amp. Includes 4 probes and english/german operation manual.
The Bias Master™ allows you to monitor the bias current safely and easily. While adjusting the Bias control pot of your amp, the Bias Master™ shows the actual result. This lets you set and evaluate the full reasonable biasing range your amp and tubes offer to find and set your personal perfect choice.
The Bias setting has a dramatic impact on the amp's response, break-up and dynamic character.

Product Reviews
One of the Novel biased probes had a continuity issue, I called and they provided me a return label for exchange. I was not willing to wait for the return process and new one to arrive. I took it apart and did the repair myself using a solder iron, they failed to pre inspect before shipment
