Where can I find the bias testing post mount thing?

Hi All,

I have searched and like talking to "Alexa", you have to phrase it correctly. I am sure I am calling the item the wrong name. I want to put digital volt display where the bias checking sockets are in the front of my ST-120. Then like I have seen others and also it looks like on the M-125 having bias meter testing posts mounted up top or in front. I don't know which ones to get. Can someone please point me in the right direction?

Thanks Scott

Great Idea!. If you get a source for meters that fit the holes in the front of the St-120, and some alternative bias test points, I would like this also. Would be nice to be able to look over and just see the bias.

It looks like they will work. I will let you know how it works out, but they feel nice and heavy compared to the all plastic ones.

I've seen people buy mini DVMs and mount in those holes, or these simple test points . . .
