So a few weeks ago a guy had a TS-50 for sale. I have always wanted one of these.
He told me it did not work and he thought the regulator was bad from what he has read on the net.
So I bought the radio for the asking price.
A few days later I decided to check it out. no TX or RX. The s-meter slowly pegs when powered up. Really sounds like the regulator issue I have seen before.
Not a bad looking rig,

So took the top cover off to have a peep at the TX-RX board.

Hmmm, something just does not look right about this board. Different than any I have seen before. Guess I will pull it and get a better look.

Strange, all the TS-50's boards I seen were all SMD but I am seeing standard through hole caps on the board.
Lets get a close look.

OMG! it gets worse!!
But hey, at least the voltage regulator is original.

I have repaired a lot of ham equipment over the years. Even some that were dogs......
So, I am not even sure if I can repair this board or not. There is one capacitor mounted upside down that has the positive lead touching the base of a To-126 transistor heat sink tab, then the wire runs down to the base of same transistor. I really wished I had a macro lens so I can show better detail of this.
This will be a fun hair pulling project. And to think I gave 50 bucks for it :p

I wonder what it is going to cost you in tranquilizers?
