One handed, do what the guy says... ONE HANDED one in your pocket.

It can’t be clearer? Where to hook what, where. One has two pots one has 4 pots. He says that at the start. Type II or Type III.

there are four large black resistors, two on each of the vertically mounted pc boards holding 4 power tubes, on each side of the amp, so two resistors are at the top edge of each circuit board, can't miss 'em

each resistor controlling bias for a pair of power tubes is centered between the two corresponding power tubes - hook your multimeter j-hook probes there, while adjusting the relevant bias pot, set for 65 mv across the resistor read on the m-meter

you can also download the manual from arc.db.ws if you don't have it
