VHT Tube Tester + Amp Bias Meter

About This Item

Set your amp's bias the right way
Tubes don't have a predictable life, but you can measure how they are performing in your amp. The VHT Tube Tester lets you see how current (measured in milliamps or mA) is affecting your tubes and where to set the bias on your amp. Setting the bias correctly is essential for achieving optimal tone and performance, and keeping your amp running safely.

Swap power tubes without fear
VHT sells this as a "tube tester"; we find its best used as a tool to find and set your amp's bias. The bias is the current flowing through the amp when idle. Once you know how your tubes are working you can find the perfect bias setting for your amp, maximizing the amp's performance and the life of the power tubes. The tester works for all popular octal-base output tubes (6V6, 6L6, EL34, KT66, KT77, KT88, 6550, and more).

This is one of the most affordable tools to measure an amp's bias, and see how two tubes perform at the same time. There is no need to modify the amp or tube sockets. You also have the option to plug in your favorite analog or digital multimeter for calibration or more precise measurements. The two foot long cables allow you to reach into any head or combo.

Get the right tool for servicing your amp and changing tubes!

    VHT Tube Tester includes:
  • Two standard 8-pin octal-base adapters with dual banana plugs, cloth covered, two feet in length
  • Adapters accept all popular octal-base output tube types (6V6, 6L6, EL34, KT66, KT77, KT88, 6550, etc.)
  • Two high-quality 3" diameter metal and glass analog milliamp meters (100mA max)
  • Additional test-pin jacks for external digital multimeter connection
  • Durable vinyl-covered wood cabinet
  • Requires no external power

I bought the bias meter. Had little problem and they sorted it out with no problem, very helpful. I could not recommend their service higher. An example of how it should be.

Needed to fix my own amps. Tech service is expensive and slow. I have military training in tube amp systems. This is the tool I needed for bias setup. Well made and professionally shipped. Will help with other band members tube replacements.

Bias system

Great quality and price I have 9 tube amps so this really makes it easy for me to bias and maintain my gear, and does not require me to be a electrical engineer...

Tube Tester

Been wanting one of these for awhile now. Had a bad experience with local amp repair shop, now I can do my own maintenance repairs on my Fender Deluxe Reverb amp. I have a good understanding of electronics so why not save some money when time comes to replace tubes etc. And set amp up the way I want it to sound, not the way someone else thinks it should sound. Lots of good reviews out there on this tube tester. Stew Mac is my Number One when it comes working on guitars and amps!

Great tool for insight into an amp!

The dynamic monitoring feature (watch the meters while playing through the amp) is very interesting. I can have the bias set well for two tubes but watch those tube behave very differently from each other while playing. Changing the phase inverter tube then can make even bigger differences. Will have to spend some time figuring out what it all means, though:)

Correct, simple and easy way to check the bias current in your PA tubes. Well worth the purchase price, especially if you use high dollar PA tubes, in your amps.
