Einstein Channel 1 Modes - instructions, schem and a board

Inside the Einstein you need to install a stereo jack (insulated preferred) and run three wires from the manual switch on the frontplate to the jack. Middle of toggle = ground on jack.

Keep the old wires on the toggle !!!!

Every now and then I get a request for a schem/instructions to do this mod . . . well:

here's a zip with Eagle (you can download a free version) schematic, board and PDF.
Feel free to create your own PCB or use the schem to PTP it.


you need 8 diodes 1N4007
3 LEDs
a 9V supply (jack)
2 Resistors (1k Ohm)
3 switches (not latching, momentary switches)
a Hammond BB enclosure
and two Takamisawa relays, type see schem. DS2Y SL2 . . . 5V or 6V.
Those are bistabil (no idea about the english word) and each has 10 contacts.

MJ1 and MJ5 hooked to 9V supply
MJ2, MJ3 and (ground) MJ5 via stereo jack into the amp.

Hello, I'm looking for the switching modes mod on my Einstein.

Doing it like you said, the switching would enable mode 1 or 3, but 2 wouldn't be selectable.

Am I right?
 
Bumping this.

I just got an Einstein 100 and I'm thinking of trying to do a mod similar to the Kruse with separate gain and volume controls for each mod.

I'm having trouble figuring out how I'd implement the wiring for the mod. Anyone have any ideas on it?
 
I ended up having some PCBs made based off of duesen’s layout - thanks!

Works great though I found an issue only later that the cathode on the CR led needing the pad run to ground as it looks like it wasn’t connected on the PCB layout.

Works just as it should though on the Einstein.
