Odd... I've not yet had a valve failure....
There are not many companies making valves for the 4AG.... that's why I asked you if you were talking about Supertech. Do you have a company in mind??

but more will be required...
I wasn't sure how much... after all... the clients valves were not going to be used, I had picked through my old valves for a decent set. So "new" valves, and had them ground, along with the 3 angle grind.... after all of that....
Chamber volumes were....
35cc, 35.2cc, 35.2cc, 35.1cc (based on beginning meniscus levels)
All in all not too bad, well within acceptable tolerance... but I worked #1 a bit more then the other three, I'll have finished chamber volumes by Monday...
Now here is the progression of chamber #2....
More to come..........
