[Amps] Parts question.

[Will Matney]

Well,
Does anyone know if they still make ceramic disc capacitors with built 
in spark gaps? They used to use these a lot in tube type color tv sets. 
These were made to arc if the capacitor voltage was somewhat exceeded. 
On the top of the disc, there was molded in a small spark gap. It had a 
little cut in the ceramic separating the two electrodes. I was thinking 
these would be handy in tetrode and triode circuits if they're still 
being made. I've not seen any in years anywhere but haven't looked 
either that much until now. If they do still make them, who is and where 
is a possible supplier? Thanks all in advance.
