SELL: Dedicated 6m Heath SB220 ssb/CW linear amplifier in 9++
condition. Amp runs a pair of full output Eimac 3-500's developing
900-1000W
output with 90-100Watts of drive. Outwardly, the unit appears to be
stock Heath in every detail except that the bandswitch now controls the
t-match exciter input tune control for a perfect 1:1 SWR. Interior
changes
include a specifically designed, broad banded tank circuit and
tuning capacitors that alllow for full 1 mHz excursions without any
retuning.Perfect for chasing the elusive DX on band openings or
contesting.
All circuits are stock Heath and all meter positions (HV, grid,rel
output) function normally. Currently wired for 220VAC but can operate
on
110vac. Complete with the Heath schematic with circuit changes, and a
spare
zener diode. $750+ shipping Ron W2CQM New York City
