Title: WANTED: ~90-150w watt class hi-fi modulation transformer Post by: K1JJ on May 17, 2020, 04:55:18 PM I am in the planning stage of possibly a pair of 4D32s plate modulated by a pair of triode connected 4D32s. Something in the 600V to 700V plate voltage, 150 watt carrier area. I want to know if there is any mod iron available that will help me zero in on my choice of tubes and power level. I have seen some nice multi-match 125 watt transformers out there in the past. I am open to suggestions. I prefer 50 Hz to 8 Khz iron or better. Ability to handle current without a reactor is a plus. We are talking about 400 mA at 600 volts on the plate. About 20-30 pounds-ish I wud guess. 2:1 step down ratio a plus. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
I am also looking at the Antek line of toroidal transformers for tube to tube modulation. Do you have any iron to put to good use? Tom, K1JJ Please contact me via PM on this BB. |
