You have to calculate the plate load impedance of the tube(s) that you plan to use. plate voltage/(1.8 * plate amps). You then take the PLI and in the ARRL Handbook they list what C1,L1,C2 you need f

If you are using a 0-1ma FS meter it is typically 1000 ohms per volt. This means that if you wanted a 2500V FS reading you would need 2500 * 1000 = 2,500,000 ohm in the meter multiplier string. I wou

I gave you the answer in my previous. Read about measuring voltage using a ammeter, which is what you are really doing. Find a 1ma full scale AMMETER and use 5 megohms in the meter multiplier string.

It is a grounded cathode design, not G-G. 3500VDC @ 300ma = 1 kilowatt input, 600W out. It would be a fun project. Looks like the Q was set to ±12. Bob W6TR -- Original Message -- From: "Bill Fuqua"
