Re: Tektronix 145 PAL test signal generator - repair (oven control circuit and maybe more)


 

Hi

I'm still looking for why my 3.6V supply has issues.

The current draw of the boards doesn't seem excessive (though I don't know what's their normal power consumption - Bar Timing board draws almost half an Amp). Q850 gets scorching hot.

Any ideas?

I do get a picture, though sometimes I loose the colors and the crosshatch pattern's vertical lines aren't perfect
