Frihed is correct that you will get better answers on the BottleHead forum under "Legacy Products" from the designers. There were a couple of variations...what is your driver tube?
It is direct-coupled with a strong turn-on. Not all my old stock tubes liked it, but coil spring Sylvania did well. New production tube didn't seem to have a problem. EML tubes weren't recommended. Again, BottleHead is the best place for accurate answers.
OPTs were EXO-035 or 036...one is 8 ohm, the other 16 ohm(I forget which are which, but they are nickel )
Good amps worth using!
