I believe the DIYAudio store can do the panel customizations using the FPD files. No need to engage a separate vendor. In addition, the DIYAudio store offers re-anodization after milling, which FPE here in the USA does not offer.

Olsond3, yep as others have noted trying to secure kit via Signal Transfer isn't easy. I am one of those who has tried and failed. Pity as it's good kit, if you can get it.

Why is Carl Huff's pre-amp implementation not sufficient for you needs?
There was also the Elektor Pre-amplifier 2012.

Thanks DM55.
I'll try to get some of my inbox freed up

I did not know that the store did machining and Infill. They use .FPD's. Are they just sending on to Front Panel. How about costs?

Finally about to start this! Couple questions-



1) Digikey is out of the Amgis L01-6354 until December. Alternatives? Antek AN-0218 - 25VA?


2) Input - I only need one input (RCA for phono). Could I remove the IO and wire directly to the main PCB? That seems to leave out the 3 second delay on the IO board. Not a big deal to leave the IO board in.



3)Another idea is to include a phono (Bugle2) in the case and run it directly to the main PCB. I will primarily be using this with an Aleph J, so it would be nice to have phono-preamp-amp connection with the ability to bypass the tone controls. Might be unnecessarily restrictive, but I can always change it later.


Please feel free to PM me on questions 2&3 since they are specific to my build and I don't want to clutter up the thread. Any general insight or considerations would be extremely helpful. Still learning on this.

Yep - its in the Chassis section under Customization Services. Prices are listed there. It's competitive with FPE, if not better. I believe they do the work themselves. The FPD files are a form of CAD files as far as I know, so they can use these.

Talema 70054K

You can wire the phonostage directly to it

Would it be possible to get the I/O board separately? I've been struggling with seemingly differing dimensions, and have now lifted some pads.
