    Hi Eric: Thanks for the heads-up re: Waveform records!
    I’m a big fan of fusion, progressive, ambient &c., as well as classical/chamber music/chorale and, and— It’s “all good”!
    I ordered a couple disc today.
    Hope things are well with you.
    Best, Don

    Hey Eric,
    Have been talking to Don re the GG Pre LDR mod, wondering whether you can assist me in doing this to my GG, I am in Australia so it’s a little difficult to transport.
    Can you please advise whether you can assist, can’t see the point in reinventing the wheel.
    Will be stickybeaking at the site above as well!
    Thanks for the heads up!
    Regards,
    Drew.

  3. Hi Drew,

    Did you get my email? The schematic for the Luddite 2 10 shows what can be done with optocouplers to replace the pot (or stepped attenuator) in the Transcendent Grounded Grid preamp. Really it will work to replace the volume control in any preamp that has a dc voltage to tap from.

    Let me know if you get stumped 😉

    Hey Eric,

    Am a little stumped here, it appears that you have bypassed the first two tubes and gone straight to the grid on the third? Can you send a couple of hi-res photo’s or a drawing please?

    I guess it is about understanding the circuit, but it has me a little bamboozle’d, this means you have the gg essentially running on one tube?

    Thanks,

    Drew.

    • No Drew,

      Don’t worry about any other resistors but those on the input tube and the volume pot. I replaced the grid stopper resistors on the input tube with optocouplers because it is a convenient place on the board to put them. The volume pot is then used to control the voltage to the LEDs in the optocouplers. Hope that clarifies it!
