 For Sale AL-811H  
AL-811H linear Amplifier. I have been the sole owner for 15-20 years. The Ameritron factory replaced a capacitor one time, and also replaced the meter lamps with LEDs. A few years after that, a local highly qualified technician repaired a minor problem.
It has always been capable of about 800 watts output, but always run at about 500 watts with about 50 watts of drive.
The amp now blows both main power fuses when turned on. I suspect a bad tube and a bad resistor.
I will sell “as is” for $300 cash. I am 81 years old, and can’t lift it any more. At this price, I feel that there is enough margin for a VERY nice profit, if repaired and resold, or a real bargain if repaired for personal use. I’ll just go barefoot. Local pickup only in Evans, GA.

 MFJ ALS-500m w/ remote, 10/12m $1050 OBO  
I have a ALS-500m amp with remote for sale. This amplifier has been slightly modified from factory. It no longer has the cinch jones plu feeding the amplifier. It’s has 1 gauge wire with an Anderson SB-175 connector that feeds the back. Those connectors are good for 175 amp which is was more than it could use. It’s also had the power wires inside upgraded to larger gauge high temp silicon wire to reduce voltage drops to the transistors. Even though it’s a late model amplifier, the PA board was swapped with an older one with 4 actual Toshiba 2879’s and it has the 5w resistors in it, not the 3 watt that were used in the later ones. It comes with a brand new remote and cables for remote operation. The fan has been adjusted to come on sooner and the air passages blocked to force all air into the heatsink. This has only been run after the PA board was swapped and tested into a dummy load. This amplifier is mint. Feel free to call if you have any questions. 757-343-1201. Mike KO4YAO
