OK I started the thread early The scope of the project is to physically remove the ridiculously heavy transformer from the Heathkit SB-220 and mount it on a separate chassis about 6 feet away. This will involve routing the High Voltage over that distance, along with the AC wiring and other wires required. A 3rd unit will be mounted at the operating level to remotely turn on power, standby and key the amp. This will be a 6 Meter only amp and it will sit on a HIGH SHELF a long ways from the rest of the station, as there is no room nearby for the amp to be placed. The only parts in the amp will be the Tuned circuits, tubes/sockets and the filament transformer. This should make it only 10 pounds or less. ( I don't know how heavy the filament transformer is) Since this is 6 meters only and the primary operation will be SSB (maybe some CW) in the 50.125 portion of the band, no retuning should be neccesary for short QSY excursions. The input and Pi Network will be set and forget. I wont need to switch the meters as I will have a Dual needle wattmeter on the output externally, so maybe I will just leave it on Grid Current. I will drive it with a solid state amp as my FT-736R is only 10W and I need 100 W or drive. So I am in the collecting data stage at this point. I will be picking up a SB-221 Saturday to begin the mods on. I had hoped to find a CHICKENBANDERIZED Amp brutalized, but this one is in excellent condition. I will save all the HF circuitry for restoration someday for HF if neccessay. Since a completely new power supply will be built, the only HEATHKIT PS component to be kept is the Transformer. One of the first items that needs to be acquired is the materials for the HV cable. I need atleast 6 feet of 10KV cable and the Millen High Voltage connectors. Here is a place that has them, but they are MIGHTY PROUD of them!!! https://www.surplussales.com/wire-cable/hvwire-2.html YIKES!!! $40 for 2 pair of connectors!! this is going to be an EXPENSIVE project!!! I will be CAREFULLY COMBING the TRW Swapmeet for these , looking in boxes of junk. Somewhere I have some of these, not that I can ever find them. they are buried in a 1000 pounds of debris. Need to score the HV cable too. Spark plug cable probably won't do. Of course the amp will all QSK'd andwith a soft start (though I am not sure if that is for the filament or HV transfomer) investigation to follow. Maybe its for both. OK this is just the Openning post, much more follow. STAY TUNED!!!
