Hi. As discussed on the EL34 Baby Huey Amplifier thread, I'm starting a new GB for the amplifier PCB and separate supply, Mk2.

The AMP PCB is designed to install the tube from the back, version of this pcb is MK2 Rev 1.5-2, bottom, dated 14-07-2019, see schematic. The MK2 version has no power supplies built-in, you need the separate Power Supply PCB. As suggested I corrected R14/R15 to 1K/2W, the correct value for the EL34 tube.
You need One (1) AMP PCB per channel, Two (2) for a stereo amplifier.

The Separate Power Supply PCB is version MK2, Rev 1.5-1, dated 23-07-2019
You need one One (1) PSU for two channels...

Check the PCB images for dimensions.

Add your name to the list and send me a private email. Then I will contact you to get your full name, full shipping address and private email to reach you.
Once we have an idea how many members we have we can have an idea of the pcb price. Prices should be similar to previous GB...

We will see how it goes...Thanks
SB

March 19th, 2021 UPDATE

March 20th, one kit still available, one buyer changed his mind...


July 12th, Will place a small pcb order this week for a few extra kits. Already sent email to the few that were interested so far. If interested let me know.

Interest is slow, but we can probably reach 20 AMP and 10 PSU. Will wait maybe an other month to have an idea of the quantity to order, and then I will decide to place the pcb order or wait a little longer.
Thanks
