If black and sticky, probably tar (or similar) oozing from
the sealed chokes. PCB, IIRC, is a clear liquid, and I doubt it was
in common useage back in WWII era boatanchors.

Thanks Uncle peter, that's encouraging news. I'm told the three large
capacitors which are sealed in a single case may contain PCB, but it's not a
problem to substitute them. I'm still undecided as to what to do with the
set really. I may look out for a tatty model which works, and swap my
restored front panel, dials, e.t.c onto it. Otherwise, I may completely
strip the guts out, and re-plate the chassis and really go to town on the
restoration. I'm in the right industry for getting plating done as 'a
favour' e.t.c, so it might be the way to go. I'd have to find someone to
re-align it for me when re-built though, as I have no access to a sweep
generator.
Any offers anyone? !!
Cheers for now.

Yep, the black goo is tar and unless the choke is running WAY hot I'd
not bother awlfully much about replacing it. As far as PCBs in your
dinsaur not moch to worry about UNLESS caps were replaced any time
from the mid-50s to say the early 90s. My thoughts on units
containing PCBs , asbestos etc; are as follows: Unless there is an
obvious problem (PCBs leaking from caps or loose asbestos powder etc;
) leave the stuff alone. There are many MUCH more hazzardous
substances that we all are exposed to on a daily basis.

Just my thoughts.

Note that naptha (paint thinner, NOT paint remover) will do a nice job
of removing leaked tar from chassis with a little elbow grease.
