Review on High-Precision Nobsound 8-Pin Dual Bias Current Probes Tester for EL34 KT88 6L6 πŸ§ͺ 6V6 6550 Vacuum Tube Amp Amplifier - 2 Meter + 2CT1-C - Cathode Current Measurement by Heather Wagner

Revainrating 1 out of 5

Blew 2 resistors in my amplifier

The first one worked for several days. A few days later I went to check the bias and the cathode resistor on one of my EL34s burned to the ground as soon as I turned it on. I exchanged it and the same thing happened the first time I used it. The resistance lit up with a bright flash and a puff of smoke. This item is not worth the risk.

Pros
  • Finally I bought
Cons
  • Infinitely sluggish
