Lots of people seem to worry about running the 32v3 on high voltage. I wonder why. The only typical problem was the low voltage transformer, which is why it's a good idea to remove all that filament power off it by solid stating the rectifiers.
I used to use the 32v3 as an exciter and had a variac on the high voltage. The 32v was rack mounted, the variac was mounted in a panel in the bottom of the rack. When I got around to measuring the high voltage with the variac all the way up, it was over 1000 volts, it ran that way with no problem for years. With the home brew 4d32 rf deck, the tubes seem to like 1200 volts without problems. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Mike > Dorworth, K4XM > Sent: Thursday, January 12, 2006 6:44 PM > To: Discussion of AM Radio > Subject: Re: [AMRadio] Good solid state/hybrid rigs for AM use > > > My 32V3 gets 107 (exactly) watts out in HV position with 121 > volts AC input > and using the original tube rectifiers.
