[Heathkit] SELL: 1 KW+ Heath 6M Retrofitted SB220

[w2cqm@juno.com]

Offering a near mint Heath SB220 retrofitted and dedicated for 6m
operation. Develops 1000W+ output with 100w of drive  with a brand new
pair of RF Parts 3-500 tubes. Rectifier board filters have been replaced
with new  330mFd@ 450VDC Nichicons. From an exterior view, the amplifier 
appears stock Heath except that the bandswitch and tank circuit have been
replaced with a front panel  adjustable exciter input  T-Match . There is
a 1:1 SWR with the input circuit excitation  to the amplifier.   Unit's
antenna relay  is fully compatible with the new solid state (DC) 
switching parameters and requires no intermediate controls. Broad banded
tank circuit allows for   full 1 mHz excursion without tuning. Perfect
for contesting and DX'ing. Redesigned HV plate choke, parasitic
suppressors, mica blocking capacitors,  and shielded T-Match have
eliminated all troublesome  spurious signals. With 240 VAC primaries
(ONLY) , the output buries the 1KW Bird 4410 slug.  A unique opportunity
for the serious 6m operator to get a big signal on the air for a
reasonable cost. Sorry, unit will not be shipped. I learned that the hard
way.  Can be picked up in the Scranton, PA area, New York City, New
Jersey (GSP exit 117 area), Timonium, or at Dayton. $875 Ron W2CQM/3
