Nanotube: the newest electrostatic amp by Kevin Gilmore!
Nov 20, 2019 at 2:07 AM Post #32 of 36
I'm not clear on all the details, Kevin if you could help me

The Nanotube is a SiC Circlotron from what I understand.


  1. Is this the latest known working PS board?
    circlotronhvpowerdualnewer2.ZIP




  1. Is this the latest known working output board?
    kgsshvcarboncirclotron.ZIP



  1. And latest known working driver board?
    kgsshvcarboncirclotrondriver.ZIP




  1. Are these ready for experienced DIY?
  2. Who supplied your trafos? Any special notes
  3. Any special build notes other than
    1. single chassis as we're near kV
    2. mil-spec teflon wire
    3. HV DMM probe
    4. ceramic heatsink standoffs where needed
    5. lift resistors
    6. any special component notes - resistor/cap specs?

Thanks so much, as always I look forward to the build

Edit: For reference Kevin's notes
Hello,
I constructed many electrostatic headphones of various sizes and shapes and now i am interested in a Electrostatic Headphones Amplifier like this. Where can i find the boards and circuit diagrams in order to construct one ?

For those interested, a few sets of Circlotron boards from the Group Buy at 'the other place' is available here

All PCBs are from PCBNet: 3oz copper (ALL boards to build the Circlotron is included)

4 x HV900 Golden Reference High Voltage Power Supply boards
2 x Driver Boards
2 x Output Boards
1 x Split Golden Reference High Voltage Power Supply includes BIAS supply (580V)
1 x Split Golden Reference High Voltage Power Supply includes low voltage supply

16x 470uF/550V, for the HV900 batteries
4x 680uF/550V for the HV PSU

(This is excess from a recent Group Buys, so not a whole lot in stock)


The kit can be used for building a KGSShv Carbon, as the driver board is almost similar to the Carbon v5 amp board although it takes a few tweaks in rgrds to servo and feedback loop.

Hello,
Do you know where can we find the circuit diagram and pcb boards ?

I wonder if anyone is interested in a board set of the Circlotron “Nanotube”? I’m planning for a new build for this year. I could help with hard-to-source power caps, transformers or even enclosures.
