TAD (Tube Amp Doctor) BIAS Master 2020 - White
Our users rate Reverb
TAD BiasMaster, purchased from Thomann and used only once to set the bias on my ENGL 840/50 power amp.
The unit is in excellent cosmetic and working condition.
I originally bought it specifically for maintaining this power amp, which has recently been sold. Since I do not plan to use any 6L6-based tube power amplifiers for the foreseeable future, I no longer have any need for this device.
✅ Purchased from Thomann
✅ Used only once
✅ Like-new condition
✅ Fully tested and working
A great tool for quick and accurate bias adjustment on compatible tube amplifiers.
