The reception is much better and less garbled. It figures.
PS. I failed to neutralize the RF.
It is possible it was due to bad decoupling caps. Tomorrow will try again.
Also 120Hz hum is still there, not dependent on the vo!ume.
A note: for neutralizing I use a bad 26 tube, which has no shorts but has open filament. The Rider's book recommends pretty much the same: a 26 with a filament pin bitten off. I found one such tube in my possession. I think it is ok, instead of constructing a transition socket.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
