Many just wind their own and experiment until they get the correct voltage.
Most overvoltage is due to amps designed in the 60's and 70's when the AC
line was
117/234; now it is often as high as 125/250 and even more at times.

One of the things I wonder about is how you add a resistor to
the filament lead since it seems it is going to have to be about
0.2/0.4 ohms or so at high current. Maybe a wire but that can add
inductance so I was never clear on that. I suspect my Dentron could
use that mod but I haven't done it yet.

REPLY:
mouser.com has many such resistors available.
