Hi! I have 2x12 cab that I am going to put a two vintage 30s rated at 60 watt each...16ohm wired in parallel to make it 8ohm...I just want to confirm that it’s ok to use it with a 100w tube head impedance matched?
Depends which 100w amp (Plexi, JCM 800, what?) in my experience, and what volume you run it at. Marshalls are rated less than what they put out, typically, so it matters.
And don't forget once you kick on your pedals, the signal increases and the speakers get that bump, too. I say this as I'm reconing an alnico blue to 65w 8 ohm spec that was in a Tweed Deluxe clone, and got killed in short order. Tweed clone is supposed to be 15w, but reality is that it's 22w clean, probably 30w cranked (if not more, depends on the biasing, etc). Then if you kick on an OD pedal, boost or fuzz...well, then you have a warped/fried voice coil and your amp sounds like a buzz saw.
But if you keep your 100w amp below 5, don't go nuts with boosts, then you'll "probably" be ok with two V30's.
Just my .02 based on client's experiences.
