Ooohh!! That looks great! (I haven’t received my blue one yet.)

 

[flamethrower1]

Received mine as well, looking forward to this build

That stereo/mono balanced board looks great! Something for me to order in the future (for a balanced build of course).

Special thanks to 6L6 for sending me the pink boards for my Wayne BA2018/MOFO build.

Best,
Anand.

I received my board today too, along with keratherm for making my Aleph J and M2 1/2 and 1/2 monoblocks.

Was there a Bill of Materials for Wayne's preamp? I can't seem to find one and I thought I remembered having one. Maybe 6L6 provided all the parts for the BA boards and we didn't need one???

Here's a good photo of the stereo PCB from the store.

6L6 did kits back then.

Just ordered parts from Digi-Key (Mouser Is out of stock on the NPN transistors). Here's my BOM:

Note: part numbers are one channel but quantities are both channels

You sir are a gentleman! Thanks!

@avdesignguru - change the KSA992 to this one to match the KSC1845 in shape (bent legs) as well as hFE (C-grade)

Good catch. Thank you. Done.

Image for the store....Glorious!

 

[6L6]

Ooohhhhh!!!! Very nice!!

Just out of curiosity ... is the shadow real or 'added'? The bottom left corner looks sharp but the other 2 corners look rounded. In any case, beautiful indeed!

Will it drive an F4? (don't need to answer that)

 

[6L6]

To clipping? No. This has gain of about 4. (12db)

Thanks!

Shadow is real—you are seeing the dimensional thickness of the board....bottom right and top left corners...

I got the PSU boards today from the fab house but it looks like one of their machines malfunctioned while silkscreening the caps. The boards themselves look absolutely fine but I've raised a complaint with them.
