Use headphones to monitor the recording process and if initially the file isn't faithful to what you hear off the phono to the headphone amp for either set of coupling caps don't even bother to compare those via recordings.
There will be. Make sure to sign up.
I am trying to accumulate parts and kits for several of the group buys and then roll it out once I have more than 50 percent of the kits currently on demand ready to deliver. I also like to see decent demand to most sets of boards, otherwise we have to adjust pricing of boards.
Parts costs will change between group buys as well as Covid has made getting them more difficult, and more parts become New Old Stock.
Shipping will also be adjusted to best accomodate at the times. As americans know if I send out something around late october or so, it will probably disappear - but that is looking like a reasonable timeframe at this point to have my stuff together.
The Group buy for salas boards is now open and will close on October 4th 2020 at 9PM ESTI am starting to send out invoices to previous group buy purchasers.
I will be sending out private messages as well with instructions as well in the next few days.Please be sure that your spreadsheet cell meets your requirements, then read the instructions in the group buy FAQ.

Mouser project basket
For everyone who ordered Ultra FSP boards, JFETs and a Minikit, here is a mouser project for most of the other bits.
Access ID: 3180e14ed4
Please make sure to log in and save it as your "own project" first before you start to edit the project.
Includes:
- R5, R6 Beyschlag alternatives as per Salas BOM
- C3, C4 Cornell Dubilier 940 Series (a cheap underdog coupling cap, feel free to delete them out oft your shopping cart)
- all other parts for phono board and bib section except minikit parts
Does NOT include:
- R2, R3, R8, R11 as their values depend on your JFET's Idss
- Minikit parts (see original BOM table for reference )
- JFETs
I double checked and updated this cart today. Some parts are not available but i left everything according to the original BOM. It is easy to find alternatives for all the resistors and capacitors.
Did i mention that minikit parts are not included in my mouser basket?

Greetings, I am just building my Ultra FSP and have a question.
It appears the C7 and C9 are reversed on the BOM:
The BOM indicates that C7 is 100mfd/50 but the schematic shows it to 470/50
and
The BOM indicates C9 is 470mfd/50v but the schematic shows 100/50
From looking at the photos it appears the BOM has C7 and C9 transposed.
Naturally I didn't notice this till C7 was soldered but that's what my Hakko is good for.
It's also very possible that I'm confused in some way.

This is some old issue that I never corrected. The schematic is correct. I have updated the BOM. The size of the caps should give some guidance too.
Hopefully all the planets align now.
