There is big thread on the baby huey amp by Marc (bandol83) .
EL34 Baby Huey Amplifier
He has posted bom and schematic , which was improved / changed upon by other members.
The following post has certain helpful links from which to take it forward.
GB for Baby Huey PCB

Hopefully those who already built it , chip in with answers to any questions that you may have .

hey all, I asked some questions over at the other BH thread but haven't gotten an answer in a few days, perhaps this thread is more active:

1) The BH Mk2 boards are fixed bias, correct? (at first I thought this was cathode bias amp, but seems not)
2) Is Hammond 159V choke suitable for PSU ?
3) What are people using for regulated filament DC?
a. If using a DC/DC converted from the 15VDC, what are you using?
b. This could also be an option: Regulated DC filament supply, but I am concerned there wouldnt be sufficient voltage overhead from the 6.3VAC tap

Thanks!

In this case I'd like to double my order.

That makes 4x el34 and 2x psu

All the items of earlier GB that were shipped are delivered. Few items are yet to be shipped, which i will do so once international shipping reopens.

i will then start with the mini -GB subscriptions.

Prasi,
You are amazing! Thanks for all your effort and followup. Be well and be healthy, my friend.

[prasi]

Thanks Francois for the kind words.
Yes, i had to make sure everyone got their boards they paid for during this uncertain time.

i still have about 4 packets all done up and labelled waiting for shipping to resume.

hey all, I have an almost full kit of parts for an EL34 that is for sale in the swap meet section. I have too many projects on my hand for now so selling with nice discounts. Thought I'd mention here if anyone is interested:

[ckwong99]

Can anyone tell me the BH EL34 Ver.2 board, how the bias measurement at which points while I am adjusting VR41 an VR42 moment ?
What is the optimal bias voltage should be got when my B+ is 400V and OPT 5K@40W deploying.
