all. Here is an ameritron QSK-5PC board which is a PIN diode QSK circuit board for many of ameritron amplifiers including the AL-80 series, AL-82, AL-1500 and AL-1200. Also works with AL-800 and AL-572. I believe this also works with the AL-811 series amps too. Lots of info online. Designed by W8JI Rated at 2.5KW This is the printed circuit board version (pc model) that mounts entirely inside the amplifier. This is good to over 60 WPM per reviews and also silenced the relay so you have a true whisper quiet shack. Looks like item was never used /never installed. Estate item, no history but manual, board, accessories all there so should be good to go. I'll price it at a bargain - half price- given I have no way to test the unit/ sold as found. New from DXE and HRO is $279.99 My price: $140 + $10 for shipping USA only. PayPal or MO ok. Please email me. *Would also be interested in a swap for a begali signature magnetic.
