Chuck,
Nothing you can do short of turning the equipment off would prevent the
final tubes to fully conduct if the bias went positive and the VOX trips the
relay. I have had it happen only once in the 15 years I have been using
Drake equipment and I only noticed it after I keyed my TR-6, very high
idling current. Fortunate the VOX didn't trip while I was out of the room.
Best way to prevent a problem is to, at a minimum, recap the bias supply in
the AC-4. In my case I bought just the bare PC boards from the Heath Kit
Shop and my own parts. My five AC-4's and one AC-3 have been rebuilt with
them.
