Look at this. Bastard tant! The 47uf tant on the primary input to the HV oscillator. Shorted and took out the fuse. Always change this cap!
Then he opens up an older 465 and it shows the 2 - 22uf tants in parallel. Get rid of them too.
My favorite quote from the video,
"I just wonder if 'e bought these and didn't have a clue as to what 'e was talkin' about."And good thing, too. If it weren't for folks like that, I wouldn't be able to afford the test gear I have.
Working on the first of the TM plug-ins, the DM502. Only one tantalum to worry over; will check it before I go through the calibration procedure. I love this Tek gear. Useful simple test instruments, complete with elegant circuit design, first rate components, and useful documentation. What could be better than that?
The only kludge is the player piano selection switch, though it is still working after forty years, so who am I to judge?
