Hurray, another project is finally done
I've had this set running for about 10 hrs this week during the very hot & humid weather. I did not experience any high voltage sag
The CRT that came with this set was a little weak and I could hear and smell some ozone coming from the base somewhere. That reminded me that I had picked up a 7JP4 from one of you guys last year with a known grid short. I stashed it away with the thought that someday I could fix it.
Now that I have a Sencore CR70, that day has come. It took four blasts from the "remove shorts" button to clear it out and leave me with a strong RCA 7JP4 in this set
The "white gunk" has
not returned to the knobs
Someone had added an external audio jack and switch. I removed them which left those two holes in the upper-right.
