I haven't posted an update to my leisurely refurbishment & repair of the Drake
T-4X / R-4A that I bought at the Shelby Hamfest in September.
I picked up a few likely replacement tubes at the Benson, NC hamfest last
weekend and replaced the one known-bad 12BA6 (V4) that was in the receiver.
The receiver is now re-capped and all tubes were checked - replaced the
aforementioned V4. Hooked it up to an antenna and am happy to say that I get
good signals on 80 - 10 now (well, I can peak the noise on 10, anyway :) ).
I've lost ambition for the day, so the alignment will proceed at a later time.
It looks great and definitely receives on all bands, which was my goal for
today.
The T-4X has emerged from its bath & bake but still has some issues. I can
hear the sidetone again, but CW is definitely working now since I replaced the
two caps-in-a-can with new caps mounted under the chassis - out of sight. This
rig, although much newer than the receiver, is not in as good shape
cosmetically, as cleaning it revealed lots of discoloration to the copper plate
on the chassis, so I'm not going to be a real stickler with this one and will
go more for getting it working. The meter seems to be working alright (thought
it was sticking before). I can't get the receiver to work with the switch set
to "Transmitter", so I may have to go in and check the master oscillator or the
VFO to make sure they've got output. I've got strong plate current when using
the receiver.
Anyway, I'm definitely taking my time with these: yardwork and other
interests/responsibilities keep me from rushing here. I'm doing it for the
fun, so no worries!
