Great sets! I have a very clean 621TS with all original tubes, and only one changed part ever (a power resistor) and it still plays very well. That said, I'd like to see your technique for restuffing the caps and getting the tubulars to look original with the colored wax and hot glue.

Thanks. My technique is similar to what others do. I just fill the ends of the tube with hot glue. Then I dip in hot beeswax to give it the proper amber color.

Alas, I tried the speaker this morning and it is indeed blown. Bah!

BTW, what is your serial number and date codes on your tubes?

I've been running the 621 a few hours each nite on a test pattern, and I've noticed the resolution has pickup up nicely. Looks to be climbing past 3.75 mhz, and the horizontal tics are gone.

I measured the 2nd anode, and the voltage is 9kv. Is that too high for the crt?

I'm guessing the CRT and the flyback are burning in. Any guesses out there as to why the picture quality is improving?
