Re: [TCML] Odd VTTC Streamer Behavior

[futuret@xxxxxxx]

Since you have a plate lead choke/resistor, the arcs will
appear subtle.  Without the choke, the arcs would be
spectacular and possibly instantly destructive.  You
can easily miss the arcs.  They may cause a sound like little pops
in the spark streamer sound too  I think.   The tube will appear
to work fine for the most part, but it may be subtly damaged
if the arcing continues.  Even using the plate lead chokes,
a spectactular destructive arc can destroy the tube in
an instant as happened in my (4) 833A tube coil .  This
is more likely to occur if the plate is red, it seems.  Yes,
you may want to try the other tube.  Possibly the other
tube may work slightly differently if they are not a matched set.
But yes, it may be a good test.  In general running these tubes
at such high voltages and spark lengths is somewhat risky for
the tubes.  I blew up a few of them when I first starting pushing
them to high powers.

Would the tube still continue to work after this?  Are these tube arcs
subtle or is it pretty apparent when it's occuring?

I suppose I could try the spare 833A I have, if it behaves the same
past 105V then I can assume something else is wrong.
