RE: P329 WG6100 HV box difference

Just speculation here, but looking at the pic Andy posted, I wonder if it's
just a safety/redundant component? It would appear to simply be in parallel
with R929 and the HV trip pot, so maybe it's there just in case the pot (or
R929) failed or someone tried to turn the pot too far one way... (Or maybe
they're trying to fine-tune the adjustment range for the HV trip a bit
more.)

I wonder why it was there too, but cleary there are two types of P329 pcb,
the one described in the manual without, and this one, with... there don't
appear to be any other differences that i can see. I have had to populate
the entire pcb with components so far, and after powering it up this evening
after a day of filling it has blown both fuses on the deflection. I'm done
for the day, i'll look tomorrow, but i can;t think that even if it wasn't
in-circuit it'd cause the fuse blow.. the hv and t901 are unknowns, and
everything else is brand new, could be an error on my part however. I have 4
others to sort out too.. joy.
 
Maybe someone might want to make a note of this for the FAQ? i havn't seen
it referenced.
