threshold 800A

np
I love my 800a but what happened was when I pulled he face plate off,the static cling kind of bent the one needle but I straightened it out but with a slight kink..It does work but I wish I could change that needle..
Anyway no big deal but what is involved in installing the stasis circuit in the 800a.?.It works well and I put in new filter caps but I may do the caps on the driver board next..Do you have a stasis board for sale?

That would be a total rebuild. The major hardware is there, but you
would have to replace all the circuit boards with new (and you would have
to design them) and all the output devices.

A lot easier to find a replacement meter. These were of a a Modutec series
called "Mustang".

Thanks Nelson
Are there any mods I can do other than capacitor changes? As far as the meter goes,its only the one needle and its just a slight kink so it does work fine and lines up.
