Hi, I'm looking for plans for a 1 or 2 tube low voltage amplifier to
go with a regenerative radio. Does not have to be the best, but needs
to drive at least 250 mW speaker, preferably 1 watt or more.

Going off topic a bit here, concerning the regen radio previously
mentioned, that I've yet to build, there are some connections I'm not
sure of, first is the A connection, this doesn't appear to be the
antenna connection, second is the B+ 1 1/5 v connection. Do they mean
A+ 1 1/5, even though it's not connected to the + filament pin?
