I thought it strange too. Also a Celestion V30, as opposed to these 'Tru Sonic V30s', is rated at 60-70W, not 30W. It might be possible that they went for a V30 type voicing in a greenback power-rated speaker, but having the cab rated at 120W and then making it THE cabinet for a 120W tube head does seem very odd.
Here's the specs on the 3120:
Four EL34s and four 12AX7s
- Power amp switchable to use EL34s or 6L6GCs (ships with EL34s)
- 120 watts into 16, 8, or 4 ohms (switchable)
Here's the specs on the 6134+ (for which they apparently - although this is nowhere confirmed except on Guitar World to my knowledge, but supposedly that's what they were told by Peavey):
- Six 12AX7 preamp tubes and four EL34 power amp tubes
- 120 watts RMS into 16, 8 or 4 ohms
By all accounts the output of the EL34 equipped 6134+ is comparable to the 6L6 equipped 6505+, which is notoriously loud.
Here are the specs of the 430A & 430B cabinets:
- Four 12" Stephens™ Tru-Sonic 30 watt speakers
- 16 ohms
- Stereo or Mono operation
- 120 Watts power handling (2 x 60W in stereo mode)
It is listed as the speaker box for the
3120 series and the
Butcher series (4xEL34 100W power section & 5x12AX7 preamp tubes). Apparently it was developed for the Butcher but they seem to be recommending it for all of their 'British' (i.e., EL34 equipped) amps.
I'm tempted to go for a 240W V30 non-Peavey cab with V30s such as an Engl Pro, Krank, Orange, or Marshall 1960AV if I can find one under $1000 (second-hand cabs here are a little scarce with new prices depressed, people seem to be holding on to them until prices rise again).
