[ARC5] Why "Noodling" About Sweep Tubes

[Ian Wilson]

I have had some trouble taming an HF rig with a pair of 5894A's
in parallel. Had the usual plate parasitic suppressors, but it loved
to take off at some frequency too high for my 30MHz at the time
to see.

I have not had any similar trouble with the 4D32 (a majestic tube)
or the 4-125A.

I would imagine that someone more experienced in isolating stages
and VHF practices in general would have no trouble with the 5894A,
though. And they do have impressive ICAS ratings.
