 Heath SB-220 HF , 1.5 kw amplifier  
This SB-220 is an outstanding amplifier. Tubes easily run a cool 1.5 KW (cw) into a 50 ohm dummy load, 1.5 kw+ SSB. Harbach power supply/ metering board and soft key conversions have been done. This amp has seen limited use over the past 14 months but is routinely used each month. Faceplate is original and clean. Cabinet has no dents, dings or flaky paint. No dust inside and no arcing on the variables. Always in a non smoking environment. Asking $1100 shipped to lower 48. Payment by Paypal (buyer pays 3.0% service fee), Cashier's Check, Postal Money Order, or Cash. No Venmo or Zelle. Willing to travel up to 2 hours in central Michigan to meet and exchange. Unfortunately, due to scammers and part swappers sale is final, no returns, no exceptions. Cabinet is left off i attached photo so the interior may be inspected.

 “AmpKeyer” — keying buffer - rig to amp  
.
I purchased this “AmpKeyer” buffer NEW. A quality USA build! It is no longer in production and are a highly sought after amp accessory. It protects your rig from a high voltage spike from your amp.
.
I used it in my Collins station with a 30L-1 amp - seamless integration. I no longer have my Collins equipment so it is now surplus to my needs. It is in excellent condition.
.
It ships with rig to amp relay cable and DC power supply with cable.
Additionally, there is an instruction document to include instructions for various older rigs.
.
Price is $65.00 shipped and insured USA.
Zelle, PayPal and check are accepted payment options.
.
Additional picture's are available to interested buyer.
