[Elecraft] FS: solid state 400/500W amp with PS

[Ignacy]

For sale: RF Power Labs A1000 solid state amplifier. Uses 4 x TRW PT9780 28V
transistors (by Motorola; similar to MRF422)). Self contained with power
supply wired for 110V. Total weight about 40lb. Oversize components. High
SWR protection.  Output filters for 160-10m with provisions for electronic
band switching. Main electrolytic capacitor replaced with a newer one with
twice the capacitance.

 It has a large sink and can operated be operated silently without any fan
although the fan connection is included for heavy duty contesting. Requires
about 15W for full power on 160m and about 60W on 10m. With input components
modified, driving requirements may be lowered. May be perfect as a companion
for K2 or K3 QRP. 

I used it for 10 years with TS-850 and K2/QRP. Worked very well through
normal QSOs and many contests.  Two big advantages were no tune and silence.
Also no detectable heat when idle. Very reliable. 

$600 OBO + shipping. Please contact off list.
