The GZ34 rectifier draws under 2A.
maybe, but one gz34 will cost as much as a nice filament transformer....the NOS 5u4s are 5$...now i think i know why
...i haven't given up, there are still quite a few hammond organ donors that used 5u4s i think. i just bid on one, 3 bucks. i think i may just win the "worst power-to-weight ratio" contest with this thing....power tranny, 10h choke, overkill OPT, and now a 3 amp filament transformer, all for what, about 1 watt....?
