I know someone that used a test rig color CRT in place of the problematic 15gp with good results.

John has done some awesome work to preserve TV history many thanks on trying. I recently got rid of a TV project because that too was fritted CRTs and the cost to ship back and forth to France was too great.

It's a shame these tubes are so tempermental given their complex structure that provides many complications. If someone would experiment making an all glass crt 15g w/ old phosphor face? Very involved but a cleaner and simpler design.

That CRT patch works good ONLY if not a purists. Thompson or others @ RCA trashed critical engineering data needed probaly years ago to rebuild this complicated tube.The efforts here are great, remember RCA spent years developing Color CRTs.

I'm interested in a ct-100 if anyone has one kicking around.
