 FS: Yaesu FL-7000 HF amplifier  
I have for sale a nice working condition Yaesu FL-7000 amplifier
Amp puts out rated power on all bands. Physically I would say its a 8 out of 10. Wired for 115v service. Tested good. Not too sure about the tuner because it was alway bypassed due to the fact that most of these amps fail due to the ATU going bad. Price is $1100 OBO. Can ship for cost or deliver to Xenia.

 Alpha 9500  

This is a legendary Alpha 9500 HF amplifier. It exceeds legal limit on all bands. Has some cosmetic blemishes per the photo, but I was getting peaks of 1800W, 2100W and 2600W out during the course of my testing (see photos). As Han Solo once said to Obi Wan, “She’s fast enough for you, old man.” Unit will be shipped UPS insured in two double boxes (original Alpha packaging) with transformer removed, bolted to plywood, and surrounded in expandable foam.
The last 9500 to sell was earlier this month on EBay for close to 5K.
$3800 plus shipping.
