Tore it down completely and then proceeded to rejuvenated it from its demise.
Added all of Mr. Bill's Mods: Ground Balance, Threshold, SAT
I like the adjustable SAT control..........
Changed out resistors on the main circuit board and inside the meter housing.
Now have a 6" coil coming for it.
Nice save! Sounds like you and I go about things the same way. I love breathing life back into old beat up stuff. Just ask my M6. It wasn't as rough as your project though! Keep up the good work.
