Damien -
We're glad to have you join us.! It's a good group, and they all love Drake
gear :-)
Unfortunately, no. The problem is almost certainly that at one point the

voltages on the PA were 'up
Thinking about it a little more, since it may or may not have
transitioned to TX, the driver or any of the other tubes that are bias
controlled can do the same at reduced voltages.
Hope there was no long term damage.
I once worked on a FT101E that had a defective socket on the grid of

Hi Damien:
Doesn't change my thoughts really. Even tho the relay for Tx would
not be engaged, and this keeps the cathodes
Hi all,
Still waiting for better weather to put up an antenna but then ready to go with
my TR4/AC4 which are fine into a dummy load, or at least they were!
Bought a, supposedly good, AC4 as a spare. Decided to power it up gradually
with the TR4 as a load. Two hours at 50v, two at 80v, two
I may get disagreement on this but I would NEVER bring up a PS like this
attached to a transmitter.
When you do that, the bias is minimal, and ven at low plate voltage, the
finals are going to be conducting I suspect. Really hard to tell what
is going to be happening. If you want to bring
