Hello Guys,
I am currently restoring a Realistic model STA-240 Receiver for a friend of mine.
Its two main filter capacitors were low in value and had leakage.
So, I pulled a few more Electrolytics and decided to make list of ones to order.
So, between cold solder joints and scratch controls I started replacing the capacitors so far, I replaced about 30 and I decided to stop while my luck was good there about a dozen of the original ones in the whole set like 6 of them are on the Phono preamp board.
A little side note is this unit was built by Matsushita for radio shahack and was only built for one year 99 % of the electroytics were Chem-Con .
Anyway Here is some photos of my handy work and you will see a few spots where traces lofted and I had to do some minor repairs .
The one thing I dread is to clean all the controls and switches I already did the speaker relay .
Sincerely Richard
