[Moon-net] FS: 2m GS-35B 1.5kw amp (plus HV power supply parts)

[Bill Dzurilla]

2m GS-35B amp minus the HV power supply for sale.
Parts for the HV p/s also available for sale.

RF deck can be seen at
http://www.pa7ta.nl/144mhz_gs-35b.html. Does not
include the power supply and control circuitry shown
on PA7TA's site. It is the same RF deck and a homebrew
control assembly w/filament, bias, & 24v p/s and
metering plus coax relays. A complete amplifier minus
the HV power supply. Used with great results by K4XR
on both weak signal and WSJT moonbounce for about a
year. Easily puts out 1500W with 90W of drive, and
4000V on the plate. Blower is quite loud at full
speed.

K4XR bought the RF deck alone, without tube or blower,
for $900 from PA7TA. He sold me the amp but kept his
HV supply. I bought the parts for an HV supply but
have not assembled them. Will sell amp for $750 and
power supply parts for $250, or both for $950.
Shipping extra, local pickup welcome. Photos
available.

Here is a complete list of the power supply parts:
* Triad Utrad PR-21 AL plate transformer, 3300v, 500ma
(weighs 27 lbs., NOT big enough to run amp at full
power)
* Completed rectifier board with 40 diodes, each in
parallel with a 1 megohm resistor.
* filter board w/ 12 Mallory 800 mfd
450v filter caps, 12 15,000 ohm bleeder resistors, and
a 100 ohm 100w glitching resistor.
* Harbach SS-100 current inrush protection module
(new)
* Potter & Brumfield W68-X2Q12-20 20 amp DPDT Magnetic
Hydraulic circuit breaker
* Douglas Randall solid state relay, 30 vdc, 24v, 10
amp
* Meter, 0-500 microamps
* 2 switches, On/Off and Power/Standby
