pictures?

RH84 is good for doing a decent sounding amp with small OPTs.

yup..lying around
forgot which amplifier i salvaged them from a long time ago
so was just wondering if there could be anything i could be making out of it

i think their last application was with a 2A3
 
oops sorry for omitting the details,

single ended, 60-65ma is rated

it sounds quite limited as to what this can be used for.. no? :(

Obviously you'll need to buy some GU50 tubes and sockets.
2 if you want a traditional SE, 4 if you want to get funky and make an SRPP/SEPP parafeed on. Yves has a good circuit you could base it on!

Those OPTs are not limited at all, you luck, lucky man!
