 ALPHA 9500 Amplifier
This is a beautiful amp. A single 3CX1500A7 8877 high power triode is what powers ths amp. It is wired for 220V and ready to go. Selling because I bought a smaller LDMOS amp that isn't quite so heavy to move around. It weighs 95 lbs. with the transformer is installed. Amp works great. It is serial number 950010130187 and was built in 2010 (13th week).
Would be best to have local pickup so you can see it in action, or I can meet within 200 miles of Sacramento. Asking $3,800 cash or Paypal. Really hesitant to ship because of the weight and cost. Contact Jeff AK6OK at 916-205-2200 or ak6ok at arrl.net

 Ameritron ALS-600 Amplifier  

Ameritron ALS-600 Amplifier. Rated 160-15M, 600 watts PEP, 400 watts CW. I do not believe this one has the 12-10M modification, but have not opened it to check (the AUX position is silent on receive, indicating that the mod has not been installed). Amp works and and appears to be operational, but sold as is. $925 net to me. Will ship at your cost, or pick-up in St. Louis, MO. US only. Lou, W0FK
