Hello,
As I was sitting and swapping lc chambers and anode leads from a set of old burnt tubes from a Marquee 9500LC to a set of mint bare tubes I accidentally slipped with the razor while removing one of the anode leads which resulted in the boot being damaged.
I was going to use this old hv lead on the new tube since they are bare but because of this I'm wondering if I can still use an anode lead with a damaged boot or is it important that the boot is smooth and even if you are going to use it again?
Or can you just use more silicon and make the boot sealed like that instead?
I find this especially hard on the Barco tubes since the boot or cap or whatever you call it is so small there. Once you've removed it you can't get it to suck to the glass unless applying alot of pressure on it which poses a problem while siliconing it since it's hard to keep that same pressure on it for the week that the silicon should sit and cure. It's alot harder to put back in when you've removed it too since the boot isn't really that flexible and the pins are tiny.
I had an very unpleasant experience with a tube I used an old anode lead on but that was because the silicon i used didn't cure at all. What happened was that when you hooked all three tubes up to the HV-splitter you would hear a very loud arcing sound which sounded more like an exloding capacitator or something and it was continous
I think what happened was that when the high voltage built up it would leak right through the wet silicon and spill out of the boot.
I'm using high temperature silicon for this procedure
Also, once the silicon has cured and the anode lead is attached t tube. Can you then apply more silicon afterwards to make sure it will stay attached or will this pose a problem?
Would be nice if someone with experience in this area would share their opinions in this thread.
