Mark III in for repair, basically just needing new power tubes. Also had 2 broken push pull pots and a broken fuse holder. Used by such famous rockers as Today is the Day, Weezer, and NOFX, and more.

High tech amp. Has a simul-class power section which biases two power tubes in class A and two tubes in class AB through the same output transformer. SO, at idle two tubes bias at about 70mA and drop to 30-40mA when cranked (class A), while the other two idle around 30-40mA and rise to about 120-130mA when cranked (class AB). Also has half power option which, instead of limiting the power in the 4 tube simul-class output section, switches you over to another 2 power tubes. This amp had 6L6s for the simul-class section and EL34s for the half power option, although you could use 6L6s for the half power mode as well, from what I've read. A total of 6 power tubes in this amp

High tech amp. Has a simul-class power section which biases two EL34s in class A and four 6L6s tubes in class AB through the same output transformer. SO, at idle the EL34s when selected bias at about 70mA and drop to 30-40mA when cranked (class A), while the 6L6s idle around 30-40mA and rise to about 120-130mA when cranked (class AB).
