Bought my TS430 second hand in 1984. They're bullet proof - it saw 12 
years of 24/7 BBS service and a stint on 30m APRS with just two 
significant faults
1. It took a while to catch all the dry solder joints on the PA PCB
2. The output stability electro on a 78L05 (or 08) regulator went o/c, 
resulting in S9+ noise across the entire HF spectrum.

BTW, in Oz the TS430 was later released as the TS43x which was a 
modified version to prevent transmission outside the amateur bands. This 
was a result of the TS430 appearing in marine band installations. The 
modification comprised a FET and two resistors, which was easily

He is a tech, but is getting a little older, and decided to have it repaired by another ham that does it for regular income.  He is happy with it again.  Anyway, that's my take on it.  If you need contact info, send me a note and I'll learn the fellow's name and send it to you privately.
