As a new-comer to this list (which surprisingly seems to be as much a
battleground for amp ideas), I would like to know more about the
"Glitch" resistor... I have heard various responses (read seen),... from
10 ohm Glass encased r's to Nichchrome wire to 1 amp 250v 3AG fuses...
In my single 4cx250 432 amp I have a 500ma 250V 3ag type fuse in line
with the 2200V HV supply and also a 100ma 250V Fast Blow type for the
screen supply these have prevented destruction of the tube, the meters
and possibly myself... I use an un-modified SB-220 which has 1970's
vintage 3-500's and do occasionally get an arc... I have heard this
described as anything from VHF parasitics to arc from the HV choke to
the plate tune cap.... Please could someone point me in the RIGHT
direction before I lose the tubes which are priced at 375.00$ each
Cdn....
P.S. The fuses in the 432 amp are in standard holders which have
prevented chassis contamination... 73 de Jordan VE2SWL/VE6...
