Hi fellow enthusiasts,
Re-capping a 589 Grunow and am a bit confused.
On looking at the electolitics, it appears that there are only 2 of these.
I will be replacing them both with 22's.
Upon looking at the wiring of these 2 cans(which have been replaced before), I notice that one of the cans has 2 leads.
I figured the one that goes to the can leg(twisty type lug to secure can)would be a ground. Upon following the wire, I found that it goes to a terminal strip on the other side of the chassis.
It is not a ground wire. Did a continuity test with my ohm meter to verify this.
Could one of you guy's that is schematic savy take a look at the schematic and enlighten me?
I am not too good on schematics yet, so I am guessing.
I am more of a parts swaping geek. Can do that, but have a hard time with schematics.
That is on my to do list for sure.
Absolute blast working on these old timers. They are all so different.
