Timmy, from my memory I believe that folks have pulled vacuums on these leakers and had them return to being too gassy to use within months. I have NO intentions of throwing this tube out. There is a group (I know Bob Galanter is a part of it) trying to come up with a way to seal the leaks on 15GP22 and 21AXP22 CRTs so that they can be rebuilt by a professional rebuilder in France, and last a long enough time to financially merit the cost of the rebuild process. I would probably not be able to afford to have it rebuilt for several years anyway, even if the process is perfected tomorrow.
I'm not crazy enough, and don't have the equipment to try redneck engineering that tube back to life in the way you purpose. I would like to ask someone who is more knowledgeable than me, how a tube can still have enough vacuum for the heaters not to burn open, but yet have enough gas inside to fail to work....Shouldn't the getther be able to deal with the gas?
I pulled the chassis about an hour ago and brought it upstairs for examination and some work. here are the chassis shots...
The fly looks good with only a pinch of wax dripped.
A fuse was blown and a replacement was slapped in at some point in the past.
And this just looks like a hack job.
The set uses a metal color crystal.
There is minor damage to the IF board where the transformer got busted off.
One of the CRT socket wires is snapped off.
I see there have been more replies while writing this.
Nick, I accidently left some of the controls on my tester up and when I connected it I got lots of purple quickly and the tester made some new sounds.... I quickly dialed everything back and did the test to confirm what the light show told me.
Jr, all the heaters work, but I haven't seen the getthers yet because between about 57 years of grime and the neck hardware they ain't visible right now.
