[JMS] Fw: PS for Millen 90881 HF Amplifier

[georgew1lsb at verizon.net]

 Hi Paul:If you can find one, a potential solution is to acquire the power supply/modulator deck from a Clegg Zeus transmitter. The PS would only put out about 1,000V with silicon rectifiers, so it would limit your input to around 200W, but it includes an audio section ending up with a pair of 811A's for modulation.  I had one here, but it was too doggone heavy for me to deal with so I sold it locally. 

Meanwhile, I found a power transformer from a Heathkit SB-200, which is almost ideal if you build a full wave doubler around it. The filament and bias windings are also totally useable for the Millen amp. 

Good luck & 73,George - W1LSB

 I'm looking for a power supply to operate a Millen 90881 HF power amp. Apart from building my own supply from the ground up, suggestions appreciated.
