[Elecraft] KPA1500 Repai turn-around

[Hank Blackwood]

I’m not sure if it’s solid state amps or what. My AL-1200 tube amp is 12 years old and has had a fair amount of use - especially RTTY. The only issue it has ever had is the meter lamps burning out. Ameritron/MFJ sent an LED upgrade kit 6 years ago and they have been fine ever since. 

KPA500 and ALS-600 have both been sent back to their respective motherships for transistor finals.  About 4 years old for each.
