I'm not sure what first attracted me to the Eico 723. It's a simple 3 tube, cw only transmitter. It covers 80-10 meters, and no WARC bands. I runs about 60 watts output.  I purchased one on EBay in February 2006. The cabinet needed repainting, the front panel was in pretty good condition. The chassis was okay, but I did have it re-copper plated. I wish I had taken pictures of the unit when received. The wiring was good, but the lead lengths on the components was rather long. I did not even turn it on. I went to work disassembling the unit right away. I used my Hakko 808 desoldering tool, which is the best investment I've ever made. I purchased it at Kiesub Electronics. I removed every component from the 723, unscrewed all the tube sockets, variable capacitors and transformers. Cleaned the solder off all components with the Hakko and solder wick. I ordered new capacitors and resistors from Mouser. It was just like building the original kit (although I never had an original kit). I have also restored the knobs, the outside rings were pretty worn. The cabinet and trim ring paint is not the original color, I used camouflage colors from Krylon.
