Works as it should!
Dual tester worked great, biasing a new set of 6L6GC tubes. You will still need to manually obtain cathode-plate voltage and calculate conversion formula (included); Unit AB switch allows single multimeter use providing mV conversion of current draw, so you can determine your optimal bias point. Overall, it's a quality product. Delivery was quick as well. Reliable vendor.Verified purchase: YesCondition: New

You NEED this tool!
This tool is indispensable in getting your bias settings right, fast and easy. Make sure to measure plate voltage and then look up the recomemnded bias for the voltage against the Jim Jones Bias Bible.Verified purchase: YesCondition: New

Good bias tool
This tool is easy to use and is very accurate. It measures the voltage-mv- across 1 ohm in series with pin 8 of an octal socket. That measurement is directly converted to ma.Verified purchase: Yes

Seems like it’s well built. I ran my multimeter with ac voltage selected ( I was exhausted and shouldn’t have been messing with the amp at that time. Anyway, blew a resistor on the 6l6 socket in the amp and the meter stopped working. Dc only. Dumb mistake. Meter now doesn’t workVerified purchase: YesCondition: New

Bias Tool
Didn't quite give me what I was looking for. Seems to work fine but unless you are well versed in reading and adjusting bias, leave it to the guys at the shop!Verified purchase: YesCondition: New

This Dual Bias Probe Rocks!
The Dual Bias testing probe is a great tool for biasing the power tubes that I have on hand. Being able to bias both tubes at a time really saves time. It works as advertised.Verified purchase: YesCondition: New
