 Looking for recent SPE Expert 1.5 FA amp
Looking for recent manufacture SPE Expert 1.5 FA amp with tuner. Prefer one manufactured within the past two or three years. No scratches or scuffs, must work as new, original box and manual. Cable for Yaesu FTdx101dx would be a plus. Scammers quickly detected and rejected. De KK8ZZ

 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. $875. Will ship at your cost, prefer pick-up in St. Louis, MO. US only. Lou, W0FK

 Heathkit Warrior w/updates $ 300.00
Plug and play Warrior. Four US made 572Bs. Now has T/R relay for modern radios. Also has the cut off bias mod done. Ready to go. Works perfect. About 800 watts out on 80-40-20 with slightly less on 15 and 10 as expected. Also tunes up nicely on 17 and 12 with no issues. Too many amps and this heavy monster is not getting used. Cabinet redone and powder coated. All work was done by previous owner. I have all the documentation with schematics somewhere. This is a heavy beast, around 105 pounds so pick up is a must. Will not ship. Also, I want to demo for you when you get here. Solid state rectifiers in place now also. Hate to see her go but the shack is small. Come pick her up for $ 300.00 and bring a team of young men for the heavy lifting. Lane ku7i Las Cruces, NM 50 miles west of El Paso. I am good on QRZ. Text msg is much preferred over email. BTW this amp only runs on 120 vac, there is no 240 vac option on this amp.
