Nice job Linuxworks!

I think a Beta 22 is going to be my next project

Do you have pics of it cased up?

 

[johnwmclean]

Linuxworks, very nice build mate. Good to hear there are no noise problems, nice neat wiring. Congrats!

from the buffalo build on works:

It's a 30VA fully shielded and encapsulated. Very well build. Have to go this way due to close proximity with the rest of the TP modules.

Nice work! But no volume control? If that is the case I'd suggest that you be EXTREMELY careful plugging and unplugging your headphones.

 

[linuxworks]

no *local* volume control.

I have another box that does that. for now. (later on, I might have something inside the b22 box but for now, its purely an amp).

not having a volume pot means I also get better performance (the amp will test better since there's no pot to smear the channel separation, which is typical of what a pot does on the rmaa graph).

as for plugging phones in, I have that a/b switch up front and so if I did want to plug phones in, I'd switch to spkrs, then plug the phones in, then switch one more time. that ensures safety.

I was thinking of grabbing two of exactly those transformers for when I re-case my Buffalo, and a third one for my MMM. Could you possibly tell me the physical size of those, and how much they cost you?

Also, what configuration did you get for the primaries? And the rated supply frequency?

Cheers!

I would also be interested to know the same about those transformers. I've seen these before here but can't seem to find them online.

SumR - Richard Sumner Technology:: Custom

I am trying to arm myself with as much info as possible before contacting Richard, just so that I'm not bugging him

 

[TeraHz]

To answer the thread: I will be building a b22+y1 dac in it all powered by sigma22. Will try to add some lcd/led monitors on the front panels as well. I am still debating over which configuration to make though.

I guess balanced b22 +y1 doesn't work?

Will most likely start in July so I will need all the help I can get. Hopefully it will not be very hard to do. Good thing I have this community to help.

Regards!

γ1 has only unbalanced output, if your β22 is built to accept balanced and unbalanced sources, then it could work.

 

[DoYouRight]

I have started collecting parts for my B22 I would like it to have BALANCED and SINGLEENDED.

How many boards do I need. So far I have 3.

I am going to use AMBs FPD files from the KRMATHIS build for mine with minor changes. Any help modifying those files is GREATLY appreciated.

[DoYouRight]

If I follow FallenAngels/KRMATHIS's do I just need a adapter for the SINGLEENDED cable like the K1K to 1/4?

 

[DoYouRight]

I want this to be upgrade proof. So in case I get K1Ks, Balanced Phones, or 1/4 SE will all work without mods. Thanks!


EDIT: Also since the B22 balanced wont work with the Y1 as it is not, what is the good DIY DAC for this besides a Buffalo32 which is impossible to get parts for? Or is it easier now?

You need 4 B22 boards and you'll likely want at least 2 S22 boards.

Read this whole page like 5 times over so you don't miss anything and it answers most questions you'll have.
