Are you speaking possibly of the Eimac YC-156? These are fairly easy to find on E-Bay and elsewhere. Medical pulls are available, and this tube requires no socket. This is c. 3CX15000 with 5000 watt

For ham use and not pushing ratings, "home-made" chimneys are fine. Just bear in mind that the Eimac chimneys are specially shaped to divert air to the anode cap to keep air moving through the fins.

A 2:1 unun transformer will work fine here; just like the ones Alpha supplied with their 77DX to SX conversion kit. That is an understatement! Under-sized wire compounded by small winding diameter.

I strongly disagree with that advice. Harris had a large contract with the Navy to build an amp that was to be mounted deep into the bowels of ships and operated in a no-time-limit, 1000 watts outpu

Can we say "NO-TUNE" boys and girls? There is nothing to tune on this amp except the input coils. Efficiency only matters if you are pushing max. dissipation limits. You won't notice your electric m

Sorry for the error; 8660 is the Harris designator for the 8122. Also, the tank circuit should be designed for a Q of 10-12 at the voltage and current drawn at 1.5 kw, not 20 kw. 73 Phil ___________
