Metal Film or Carbon comp Help...!

[jordana@nucleus.com]

Hi.. I have had several replies to the affirmative, but I am not wondering
about DC effects... I am wondering about RF effects the Metal FIlm
Flameproof resistor might have in the grid ckt of the 8873 tube...it is
cathode driven, and gets biasing Voltage on the grid through the
resistor.... there is a coil and resistor network just before the 33 ohm 1
watt C-C resistor... Thats what I would like inout on... Thanks though to
those who have replied so far... 73 de Jordan...
