*RCA 621TS owners: need CRT input*

[John Folsom]

A while back, a large quantity of General Electric type GL4592 7" alumimized CRTs was discovered at Fair Radio Sales (50 or more). These turned out to be good mechanical and electrical replacements for the 7DP4. Fair Radio was selling them cheap, and word spread quickly, and the collecting community snapped them up. The event my suppress the demand for a 7DP4 replacement.

I think you may be right.

If I didn't have one of the GL tubes already I'd be very excited about the possibility of getting a new tube, as it is I'm kind of in the position of saying if you need one more to make a viable order and the price is right I'll take one for possible future use.
Who knows, I may get another 621 some day and need one.
