Henry 3K Classic Mk ll: I have a fully tested & 100% operating Henry 3K Classic.
This is the Mk ll model which runs one Eimac 3cx1200a7 tube.
This amp was documented by Henry as being first put into service
in November of 1987. From all indications, it has had little use.
The cabinet is in excellent condition with a few very minor surface
scratches. There are no dings or dents at all. The front panel
does have a small rub in the black paint above the tune control.
All controls operate smoothly & all lights are very bright.
This amp is clean as a hospital inside. No corrosion anywhere.
HV runs around 4,000V (SSB) & 3200V (CW) Legal limit is easily
accomplished with 100 watts drive.
I have 14 digital pics available for you to view.
I can take this amp to a packing company to crate it for
shipping if necessary. Would prefer local pickup. I can
also drive it part way for a fee of $1.00 per mile round trip.
Asking $3200.00
trade in Icom 756 pro lll (late model)considered.

SWAP - SB-230 excellent: I recently bought thinking that I could get by with running an amp at this QTH but that wasn't to be. Beautiful linear - puts out 560 watts (thats 85% of full power) with 100 watts drive. Wired for 220V but can be changed to 110 V. No manual. Looking for an even up swap for a Corsair (with no pto problems) or will kick in cash difference for FT-102 ( with no relay problems or any other issues)
