The outputs idle at ~3ma, so you can actually lay your finger on the side of the output tubes. That's why the big power supply ( about 3000uf at 500v), it has to have the electrons very handy to go from zero to 60 in a nano second.  The 6LR6 seems interesting. http://www.duncanamps.com/tdsl/show.php?des=6LR6
You'd probably want regulated screens though, which is no big deal if you don't mind a little sand. |
You are way above my level of knowledge with this stuff.
I play with "Black Market" sweep tube RF amps. I'm getting out of them and have deceided to build a huge graphite tubed beast.
Now I will have no use for all of these sweeps. I've always been intrigued by those 6LQ6 powered Mac's built in 68-70 or so.
