Don't forget to try the 6GH8's first - they'll check fine on a tube tester, but fail as a color burst amp/oscillator. We used to use those RCA's to actually test used 6GH8's - if it worked in an RCA color circuit, it was considered good.

Their use in color circuits was probably a stretch - they were originially designed as horizontal oscillator tubes. There's a big difference in 15,750 Hz and 3.575945 MHZ!

Cheers,
