 King Conversions 6m Amp
Have a King Conversions 6m Amp built on a SB-220 that has not been run since Lou W1QJ at King Conversions built it for me.

By the time the amp was done I had an solid state amp that covered 6m, so it never has been used.

$1000 plus shipping from 54220

 Icom PW2  
Clean works 100%. All cables. The amp works like it should. I’ve decided to go a different direction. ( back to an ole Henry 3k Ultra) anyway nothing wrong w it. Clean all papers and cables. The other box is going to have to be taped well and I’ll put it in a good new box. $4750 plus shipping. That’s gonna save you about $1k tax and shipping kills you. I also have 2 Icom 7610 radios. One is about 6 months old $2500. the other a couple years old $2250 plus shipping on those. Thx. Any questions call 918-810-6767. Thx
