I polished some stock knobs with stainless handles. The face plate is silkscreened in a silver similar to stainless. I will try some black push buttons at some point although the stock one look good as is.

Just put my black face plate on Stainless steel covered back plate. Still need to polish some knobs to match.
I have three or four black face plates for sale. Just like the gold ones I had but in black with silver white silk screen. Pm if interested. I listed on eBay but Ebay's extra costs has to make me put to high a price there.

I have being playing around with the Khorns with this amp. I have a small ground loop noise out of the speakers. With inputs disconnected It goes down in volume when I turn the volume pots down. The noise varies as I turn up the pots with most noise at about 1/2 volume. It it not loud at all but just noticeable between tracks.

Before it get to excited any ideas anyone?

It is full WOPL with everything. It has proper star ground setup.

I guess I need to look at the RCA plugs, although they are new switchcraft one

AC input is 2 lines only Glenn??? No chassis ground from AC cord?

No ground connected Joe on AC. It's a very low level lower frequency hiss from both the woofer and mid horn. Now these are very sensitive speakers but it just is a louder than I want. I guess I will put in on the bench later. It works fine otherwise. I will first remove the input pots and RCA and see what happens there. I have been looking for 12-24 position fixed resistor volume control as the variable ones can give some inductance. Here is what I am look for in a smaller size
