Were you ever able to locate a replacement toggle switch for the ST-140? I am seeking to replace one where the lamp has gone out - if you know of a rocker switch replacement please let me know. (this particular ST-140 has a rocker switch and not the older-style push button switch).

As far as grounding - I added an IEC connector to an ST-140 and used only the black and white wires (no ground).

Toggle switch found! I measured the hole in the B&K amp last night against the posted dimensions.... it's ordered and I'll post pictures after it is [hopefully installed].

Update:

Received the purchased rocker switch and installed yesterday. Covers the hole in the front panel perfectly. Slightly shorter than the OEM switch - but still covers the opening just fine. Works perfectly!

The light in the rocker switch is not too bright - which I find distracting if your power light is glaring at you while listening to music.
