The first set of caps lasted 30-40 years. Would the new caps last
less than that?
I think it is more likely that the cinch connector would become loose
and the pin that carries the bias would become disconnected. That
happened to me. Not a red glow, bright orange plates. I probably
could not duplicate that (and the angle of the connector) if I tried.
This is after I did the AC-4R upgrade to help preserve my (now fried)
finals. I did have a spare set.
A locking connector would be nice.

Gosh..
I thought about that, but here's no way to crowbar the bias circuit.
in the old supplies, the damage is caused by a "lack" of bias. So, if
there is a failure of the bias supply, i.e. it quits, how can you fix
that?
the only way I could come up with would have been a system that
deprives the transformer of it's primary voltage, shutting down the
supply. It would have to default in the off position too, as you
would not want the supply to cycle on, find the missing bias, then
shut down, the power up, find the missing bias supply, shut down and
on and on.

Is there a provision in the kit for a crowbar circuit to safeguard
the rig if the bias (or other) supply fails?
