Hi there Is anyone has modification to Alpha 76 PI-EL and Plate choke to put it on 30, 17 and 12 Meters. It tune on 30 using 20 position, on 17 using 20 position and it tune on 12 using 10 position b
Be very careful using the Alpha 76 series amplifiers on 12 meters. ETO used a plate choke that was intentionally resonant around 26 MHz to prevent use of the amplifiers on 11 Meters. The amplifier h
The only person that I know who has a good mod for what you are talking about is Dick Bryd. His mod works. All the others don't. I know because I had a mod in my Alpha 76 that was supposed to work. I
Use a B&W 802 or an Ameritron. Carl KM1H _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps
I would recommend a home made choke wound on a teflon former with a length of ferite rod inside. It is quite easy to obtain some 500 microhenries of inductance with resonance around 700 kHz (really,
I just measured a choke sent to me by some ham that used a ferrite or iron core and it was terrible. Came from some KK5 or K5 design on the web. It had a ton of inductance, far more than needed, but
