UPDATE!! Turns out what I need is a 21DEP4. NOT a 21ESP4. I think the ES is a 90 degree gun and the DE is a 110 degree.



I'm looking for a very good/NOS/rebuilt 21DEP4 CRT. Any one have one out there? Any equivelants? It is for a GE console. Thanks, Julian

I don't see any subs listed..

I checked the old Radioshack catalogue website and they showed three tubes that subbed the 21ESP4. 21CEP4, 21DEP4 and 21DAP4. 1964 price $26.95 .
