I finally set aside my pb-7534 after doing a bunch of work to it and getting it to turn on. I could not figure out the issue with contrast it was having, neither subcontrast or contrast pots do anything. I got a picture that only shows some of the colors. I decided to set it aside and install a 2933 a friend of mines brought me from Japan last year. I had to rebuild it cause it was labeled junk and had the horizontal yoke connector traces burnt. After a full recap and repair of the horizontal yoke connector traces it seems to be working. I had it raised of a box of M&Ms, I did not want to cut and splice wires. A buddy that works construction will build me a platform this coming week for me to permanently mount the 2933 chassis. I was able to test both 15 and 31khz and both looked great.
