That HT-18 is working fine Dennis on the gray HT-9 and its currently used
with a SX-42. Im using a prewar Meissner with the black one and the SX-28.
They are sitting stacked with a couple of 2x3's providing some air space so
the lower one is strictly a monobander for now!
I did replace the 866's with their black plug in SS replacements and both
have silent muffin fans moving some air around. I get around 125W on CW and
100 on AM with all selected tubes; the SS rectifiers made a very little
difference in the HV.
