I'd never used one of these and just wanted to post that this is an easy way to bias your amp. Granted it's nothing like the ease of an MTS or Eggie but sure beats the heck outta probing the pins and doing the math. Swapped the 34's in my Carvin T100 for 34L's and KT77's and this thing worked great. The guys from Eurotubes were very helpful too.
