EL84 Tube Type Review

Review Notes
Tube reviews written by John Templeton.

For these tests I was lucky enough to secure the loan of some classic amps and some modern gear as well. The test amps used in this round included:1961 VOX AC30 – No top boostMid 60’s VOX AC10 – TwinFender Blues JuniorFender Pro JuniorAll of these amps are combos and put maximum stress on power tubes when it comes to physical vibration and heat build up. The VOX AC30 should have a health warning for tubes since I have yet to encounter a harsher environment to operate in. I know that a lot of Boogie fans would like to hear how these tubes fared in the .22 Caliber and other smaller Boogies. Trust me, you can’t handle the truth. On with the show.There has not been a lot of space devoted to this tube in the past. The main reason was that current production provided a limited selection. Let’s forget about New Old Stock for the time being. They’re out there, they are expensive and sometimes represent the dregs of production.
