Well that's no good. Let me take a look.

Fine, you win... It's back.

Yep, that one was already on my list. It was used in the Swiss Things and something else but I can't recall what it was off the top of my head...

No. It's temporary.

I had to purchase the (USA manufactured) components from the USA, then ship them to China to have them soldered to PCBs. When the final PCBs were shipped to me they were considered a "Made in China" assembly and tariffs were charged for the entire value, including all USA sourced components...

Correct. The footprints are 1206 for the 1uF and 1210 for the 10uF.

I've used J201. I didn't side-by-side A/B it with a 2SK so I can't compare how they performed, but it seemed to work fine. I can't comment on the opamps.

They both use the same microcontroller so they behave identically. You can wire up the DPDT switch to do the same job as the Bypass module (more technically, since you aren't bound to the true-bypass wiring scheme).

Which ones specifically?

If it's the through-hole version I'll have some in a few days.

You'll need JRE (Java Runtime Environment) installed if you don't already have it on your computer. Aside from that, there's nothing more to it than downloading the appropriate SpinCAD .JAR file and double-clicking it. No installation necessary, it just (usually) works. :ROFLMAO:

I verified a few new prototypes this week and have three or four more on the bench to go. Totally forgot to order parts so I'm scrounging things from my salvage boxes to make it happen... Traced a Mizuki... Wrapping up an EEPROM programmer utility...

1) Yes. 2) The FV-1 Development PCB only accesses the first three programs on the EEPROM (like the Pythagoras PCB). It'll write all eight, but due to the toggle switch it only runs the first three. 3) You can use any CH341A compatible programmer. SpinASM files are plain text files that can...

Catalinbread does this on some of their new designs. If you do include the cap you'll need to omit it if you use a 1044 or 7660, I had oscillation issues leaving the cap installed with anything other than an LT1054.

Correct, it's a Klone, it's buffered bypass.
