 FOR SALE ALPHA 87A   
Amp is in perfect condition. It does have the ALPHAMAX firmware. Also, I have the original manuals and CD. I installed a matched set of tubes from PENTA Labs (1600.00) 11/2022. (I have the receipt) I haven't used it much. I would prefer pickup as it is very heavy and I would like you to try it first. I also have a spare set of IMAC tubes that could be included in a deal. The gain was the same as the new ones. I'm asking 3100.00 for Amp and 600.00 for the tubes. I will not sell the tubes separate unless the buyer for the amp doesn't want them. I will entertain offers for both. Don't hesitate to make an offer. There can be a very good deal here. I appreciate any offers!!

 For Sale Icom IC-PWI   
I have an IC-PWI Icom linear amplifier I have no need or room for that came as part of another transaction. I have tested this and it works perfectly. On a scale of 1 to 10 with 10 being new out of the box and 1 being a parts donor this is a solid 8.5. Cosmetically it's in excellent shape with a scratch as pictured on the one side. It is missing the name plate you would install if remoting the head unit. The rear fan has the bottom of it's plastic frame broken, but that too works perfectly. It's set up for 220, and will come without an adapter as pictured. If you need more pictures please let me know. $2000 plus shipping Jim McGregor W9WL 1-360-708-0830 majormed at sos.net
