hey butter, you are a man of my heart, don't you just love those turrets for wiring?
old school hv rect stack, caps and resistors across each diode,
this is kind of scary, but hey, its only a heater supply,
"just do it!" grab and build high current rectn stack from 1n4001's,
we need more rosin,

this is a nice compromise between the ham radio guitar amp job up at the top of this thread, and the hp mess i kludged up,
this is the Western Electric 121a preamp with the 618b and 197a xfmr's:
OT:
this new mercedes is coming out in about 6 months.
this car here will be chopped up, as it is a proto, and has no legal VIN.
wtf, over? ??? let me drive it first!
dig the retro chicks,

Whoa... is that a giant amp prototyping board with some kind of built-in variac?
Yes it is. In addition to the variac, it has built in 6.3 & 12.6 VAC transformers too so I can leave the filaments up when swapping out partz.
>Don't know it; your experience?
I've just started messing with 6DZ7's. Kind of a unicorn tube. Too cool not to build something with. If you got them, smoke them.

In all honesty, It hasn't been turned on in a few years. I found out what they're worth and weighed that against my crapmanship and knowledge. Decided to put them safely away, out of the reach of children such as myself.
