 Dentron Clipperton QRO amplifier $700  
We have a Dentron Clipperton QRO amplifier for sale today. It has full output and covers 160-10M with 4x 572B tubes. Currently wired for 120VAC, but can be switched to 240VAC, if so desired. The breaker for the outlet is the limiting factor. On a 120V outlet, you can see upwards of 900W on a 20A breaker. On my test bench with a 30A breaker, output was roughly 1240W into a dummy load. It’s a small footprint desktop amp with a 3 second warm up time, tunes easily and has a tuned input for each band built in. A very nice amp that is very simple but effective. Currently do not want to ship the amp, but willing to drive to meet if needed. I’m asking $700 or best offer for this amp. Can test at my QTH if you’d like. Only selling to make room as I have an Alpha 77Dx two tuber I use as a daily. Any questions or concerns, feel free to email, call or text me at 757-343-120 (one).

 ALS-500M mobile HF amplifier -$900 OBO  
Hello, today we have an ALS-500M mobile HF amplifier for sale. It’s a late version with the actual Toshiba 2878’s in it.

Provides full power on all bands and has the 10/12M board installed. Also included is a brand new remote control head for the amplifier. I’m asking $900 plus shipping, but am open to reasonable to offers. Feel free to email or text me 757-343-120 (one) with any questions. Shipping is from Norfolk, VA, or local pickup available.
73,
