I'd bet on a 5/64" Allen but it's been 30+ years since I had
my hands on an MLA-2500 so it could just as well have been
1/16"or 3/32" but nothing larger than that.

Mine are regular Allen screws in my MLA2500. Allen and Bristol wrenches not 
the same thing. I just use a regular old set of all sizes in one folding case.
Bristol wrenches are used on old Collins equipment, like the 75A4. I let my set 
go when I parted with A4 years ago.

If they are metric hex wrenches any good hardware or commercial fastening
house will have them and so does Amazon.. Be sure they are to
Bristol wrench.  If they  are also easy to on Amazon or many other sources
including the Bristol Wrench Co. the original manufacture. fing, just
google them.  Allen was the original manufacturer but the common term now
is hex wrenches.  If there a unique Soviet design you are on your own but I
bet they are metric hex.

Has anyone here attempted the tube conversion for the Dentron MLA-2500
from
the 8875 tube to the 3CX800A7?

I have the instructions laid out by LX2KL and I have a filament
transformer
for the tubes.





Thanks
