 For Sale: Alpha 8410  
I am changing my station over to a solid state amplifier so my trusty 8410 has no room on my desk. This amp will do legal limit all day long without the slightest effort. Amp has 2 4cx1500b that are full output and have zero grid current. I have the original double boxes but not the transformer box. I WILL NOT SHIP THIS AMP, so please do not ask. It is too nice to trust UPS or FEDEX to not drop it because it weighs almost 90lbs. I will gladly meet within 200 miles of my QTH or you can stop by and pick it up. The selling price is 3800.00 and there will be no returns. I accept Apple Pay , Zelle or cash. My QRZ email is good. I might consider a trade for a higher end over/under trap 2nd amendment item
If ad is still listed, amp is still available

 FOR SALE Tokyo Hy-Power HL 2.5Kfx  
"new condition" Tokyo Hy-Power HL 2.5 Kfx solid state linear amplifier. I am the original owner of the best linear amplifier ever made. Hand selected by then president Nobuki Wakabayashi, JA1DJW, this quiet desktop amplifier will deliver legal limit with just 65W in. At 100W, the amp delivers a clean 2500W. That's an extra 1000W of distortion free headroom. At 55 lbs., this compact amplifier has a massive linear power supply. In today's dollars, the amp would cost over $7,600. $4,200 plus shipping. Local pick up in Atlanta area. Sold by a charity, the amount paid is tax deductible. This amplifier is for seasoned operators who utilize high quality resonate antenna. This amp is wired for 240V 15A outlet. Can operate 200-250VAC. For broadcast quality AM, 500W carrier is recommended. I have other top notch equipment for sale as well.
