A couple of things. I purchased a K7000 chassis, and along with it a replacement flyback and a cap kit (twisted quarter). Nothing dangerous there, I hope.
In truth I didn't check the board out all that closely before I replaced the flyback beyond cleaning up the flux on the solder side, but when I did the cap kit I noticed the board was stamped with P538. Does this automatically mean it is the Zenith version of the K7000? Everything seems to be working fine with the new flyback, but I thought that particular model's flyback was obsolete and could not be replaced.
I also noticed that the B+ adjustment was not factory sealed. After reading a few threads on the subject of how dangerous it is to adjust this, should I be worried about x-rays? I don't know if it has been played with/moved before it got to me. B+ voltage is reading 154 vdc, but again, everything appears to be fine. I will replace IC4 when the parts come in to hopefully get the voltage down under 135.
Any input appreciated. If I am setting myself up for something down the road I would rather ask now than after I sterilize myself....
