Hi everyone:
I'm a vintage audio enthusiast who has enjoyed many happy years with my American made B&K ST-140 power amp.
Although I can't repair this myself, a friend of mine is willing to replace the lighted toggle power switch.
One user found this one: Snap In" Lighted Rocker Switch SPST 20Amp 250VAC
Anyone have an idea where I can find one of these???

HI everyone: I believe I found the part on Amazon. A prior ST-140 owner reported success. it's :
You need to be sure.
That switch is a SPST (single pole single throw) which means it can only switch one wire such as the live one. Many switches have two rows of contacts (DPST) or two rows of three contacts (DPDT). DPDT = double pole double throw.
You should visually check whether yours switches just the live or whether it switches live and neutral. Switching both live and neutral is better practice although either work as an on/off. You can easily tell just by looking.

That is a simple single pole type and presumably with a third wire for the illumination. The one in your picture earlier (post #4) show the centre and right hand pins as the switch and the pin on the left being the neon and built in resistor. Those details are moulded into the body. The neon symbol is that circle with two lines in it and the resistor is the rectangular symbol.
It looks that way based on what I see. It is a single pole (it only switches the live side) and it has the illumination.
Success!! I was able to confirm that the current Carling Technologies switch, available via an Amazon seller, is the correct replacement for the
classic B&K ST-140 amp. It took all of 2 minutes to install!!!
