    Stokes,

    I couldn't find a 120-volt LED at Radio Shack. I found a number of different LEDs, some requiring a few volts, some 12 and others 30 volts, but nothing as high as 120.

    Olddawg, there's plenty of room next to the switch to install the LED. I don't want to remove the phono pot because it would affect the amp aesthetically. It just wouldn't look right without the middle pot, given that it has a dial indicator there and such.

    I'm debating trying to use the middle knob area as an FX mix. Any reason why I can't install a 1/4-inch jack in place of where the RCA jacks used to be? And if I wanted to create a 1/4-inch line out, where would I grab line level audio output?

    Thanks!

      The light I'm talking about isnt an LED it is a small 120vac pilot light.If you cant find it,drop me an email,I'm pretty sure I've got a couple in one of my drawers,I'll send it to you.You can make a "line out" from the output jack with a couple of resistors and a seperate 1/4" output jack,but you have to keep the speaker hooked up when using it.If that works for you,let me know,I'll look in my notes and find the values for the resistors,and explain the hook-up.

        I'll go back to Radio Shack and look for a 120-volt pilot light. If I strike out, I'll let you know.

        About the line out, yes, I always plan to have the speaker hooked up. I run an active DI box at live gigs that has a 4x12 speaker enclosure emulation. It's very realistic and allows me to really get a big sound out of many of my low-wattage tube amps. I've done gigs in very large venues with just my 5-watt modded Valve Junior

        My on-stage speaker is a UK-made Laney, sealed-back 1X12 with a Vintage 30.

          Making the line out is easy.Just get a 1/4" jack and mount it next to the speaker out jack.Take a 22k 2 watt resistor and connect from the hot of the speaker jack to the hot of the line out jack.Then wire a 2k to 3k resistor from the hot of the line out to ground.Those values dont have to be exact,but you want about a 10:1 voltage divider,I would keep the value of the larger resistor under 100k.Dont use a shorting jack for the line out.
