Panasonic TR-904R help

[Dave A]

Brian,

That info did the trick! Pin 5 for the G1 to be exact. The odd thing is that it indicated as a 12v tube. Nothing below that and went up to 15v. I went with that and did no damage and the filaments looked ok. The old pix was grey mush.

I could not get to the sphere website without a computer lockup. I pressed on in the dark.

I cooked it at 15v for a bit and got about a 15% indication on the meter. Very dead. Shorts removal did nothing.

A long stay on the rejuvanation plug with the Beltron cut-and-repower format got it up to about 40% on the rejuv meter which got it back to useable condition. The life test showed very good with a 17 second hold before drop-off. 10 seconds is the Beltron standard. Fairly bright and no blooming with good contrast and focus. Not 1984 standards, but ok for me.

Some tuner cleaning and some vertical adjustments will follow along with pix when I get a good signal.

Beltron rules! Regards,

Dave A
