Refurbishing BC221
 

I'm trying to get a hold of a tool that will undo grub screws
securing the front panel knobs on my venerable BC221, can anyone suggest
where I can get a hold of one, a modern equivalent and/or something that
can be modified to do the job ??
Although all BC221s were provided with the tool (stored in a
clip beside the spare valves) I've never seen one and can only guess
that it must be something like a very small Phillips screwdriver head
but with a parallel rather than tapered tip. It must also be less than
3/32" dia 'cos I've just tried to make one by hand out of 3/32" dia
steel rod and that was too big, don't think my eyesight is up to hand
filing the cruciform tip in any smaller dia rod, hence a request for
help !!
My BC221 is still furkling along after 63+ years (& only c/s -
There, I've said it !!) out of calibration) but I think I should at
least try & smarten up the case with a good clean and a bit of fresh
paint. Who knows, it's probably got more chance of making the century
than I have.
Thanks
