Kevin,
Swap the 6EJ7's one at a time to see if it fixes it.
73,

Subject: [Drakelist] Noise In R4-C
Hi All,
I would like to draw on the wisdom of the group here. My R4-C seems to
be developing a sort of frying noise when I am listening. It is really
apparent on SSB but also now is getting worse on AM as well. It does
not seem to effect audio quality but is running competition at times
with the received signal. Does anyone have an idea what this might
be? Someone mentioned that there is a particular tube, perhaps a 6EJ7,
that gets gassy and can cause this. Any thoughts?
Thanks all and very 73.
Kevin :)
