GB for Baby Huey PCB

[zintolo]

Start at 40 mA, then raise up to no more than 50 mA.
In between you should find the right spot sonically.

Thanks Zintolo.
However, which two measurement points on the board should for 40-50mA?

 

[zintolo]

Take a look at the attachments of this first post:
EL34 Baby Huey Amplifier

Specifically this:
https://www.diyaudio.com/forums/att...amplifier-adjusting-amplifier-27-jan-2018-pdf

It's TP1 and TP2.

 

[ckwong99]

Thanks again Zintolo.

I understand and downloaded all file.

So when i measure between TP1 and TP3 , i need to get 0.5V for 50mA in R43 (10 ohm)

And I measure between TP2 and TP3, i also need to get 0.5V for 50mA in R44 (10 ohm)

Is it correct ?

Hi Prasi,

If, by any chance, you have any el34 pcbs left, I would be happy to buy them.

Cheers,

Just a FYI on the EL84 BH board ...
The positioning of the driver tube is 1mm off centre wrt to the power tubes, so that means if you make a template from one side of the board, make the holes, and then flip the board when fitting, there will be an annoying offset with the socket and hole for the driver. Don't ask me how I know :-/
I'm not sure if it is even an issue, but I'll raise it anyway.

 

[zintolo]

Thank you OldHector.

Anyone has an autocad file of the needed holes?
I'm going to make it and I would like to do it with CNC/lasercut.

Thanks.

 

[prasi]

Hi zintolo,
i will share the dxf file tomorrow for all tube holes looking from component side (resistor and cap side).

hello xbitwise,
i have about 6 el34, let me if you need a pair or more. i will mark it up.

To others,
shipping has not yet started. i have lost hope on when it will start, there were too many promises broken by postal dept.
edit: attached autocad file for el84 pcb

 

[itsikhefez]

Thanks alot prasi.

Due to the uncertainty around COVID, do you think it is possible to provide the Gerber files and I can attempt to get some fabricated locally ? I have never ordered PCB's before but hopefully with the forum guidance it should be relatively straightforward?

 

[xbitwise]

Hi prasi,

Thanks! Please put me on a pair of el34 + psu.

Hi zintolo,

[prasi]

ok, done..

 

[zintolo]

Thank you Prasi, well receipt, it's socket side, so I just drop it on the top view of the upper side of the chassis to drill holes.

 

[anystereo]

Hi Prasi,
Is there any (2) el84 & (1) PSU boards left?


Thanks
David

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.


BABY HUEY EL34MK2+ EL84+PSU GROUP BUY - Google Sheets

Hi all,
I have now shipped the remaining 4 shipments of earlier main GB as shipping service has begun though there is heavy rush (see google link above with tracking nos updated).
thanks bfpca, eldervanyar, bloozestringer and titano. Shipped your packets finally. Thanks for hanging in there.

For the mini GB subscribers , it will be few more days wait as I have begun shipping for the LT4320 GB.

Regards
prasi

 

[Toaster79]

Prasi will you be able to ship the rest of the orders any time soon? I still haven't received your email with payment details regarding my order.

Thanks you for your effort.

 

[bloozestringer]

Thanks Prasi. These have the Mk2 PS board that would benefit from the mod proposed by Ian correct?

 

[prasi]

These are the MK1 PS boards , hence mods by Ian have to implemented manually.

Hello Toaster,
Like I said, mini GB people have to wait a bit more (may be 10 days) as I have to fulfil my commitments in the other GB (LT4320 rectifier and PSU).

regards
prasi

 

[dch53]

Thanks for the updates Prasi. I hope international shipping being on again is a good sign for your area.
