Matched Balanced Pre-Amp Valves How Are Pre-Amp Valves Matched/Balanced? You might not be aware but no valve manufacturer will test for matched balanced pre-amp valves. So quality valve sellers invest in good quality test and characterisation equipment so that matched balanced pre-amp valves can be identified.

All of us that have a valve / tube amplifier at sometime find our lovely favourite all valve amplifier suddenly starts blowing fuses. Sounds like a disaster has happened and out wallet is about to take severe damage. Has the amp gone to the great gig in the sky ? A Vox AC30 CC1 blowing fuses was what was presented to me.
