G'evenng...  Using 4CX type tubes.. I've had a short in the and its built in
bypass cap/ screen ring to chassis in a Eimac socket.

While waiting for a replacement in this HF amp, is there  any problem using
the  socket WITHOUT the ring  but using an external bypass capacitor  from
the  screen pin#1 to chassis?

I appreciate optimum bypassing of  screen in VHf and UHF use but is it
strictly necessary in HF. I am aware of reverse screen current but that's a
different  animal.
