Can anyone tell me where relay pins 3 / 7 / 8 would go in a 2203 Marshall? Or ...where is my signal coming in / out of that relay ?

See post #2. pin 3 goes to C27 in that dwg.

Thanks! how about 7 and 8 ? There are no 220k's or 47k in the early stages of 2203 preamp

7,8 & 10 are not used.

Hi , that pic your looking at shows how to do the foot switch but its talking about a different amp ( marshall 2550 ) I guess.

your 2203 will be different best to try what nickb showed early in the thread for your circuit.

Me too.

Ok , i gotcha ...so what about pin 12? my relay has 8 pins? assuming i just need to find the coil +/-

Seriously? It's right there in the drawing. There's nothing I can add.

I'm trying to catch up on this one, but the attachment link in post #37 above is busted, and I think you guys are each talking about different diagrams anyway?

yes...and i built the pcb last night. It puts out 4.95 vdc. Havent done the relay or jack yet

[Valvehead]

Ok..i have the pcb done and it puts out 5 vdc.

Can someone Please help--i have a few questions ?

#1. the circuit is in post #24 .. amp is a 2203 , do i need to remove the Lo gain jack from the amp?

#2 the relay is this one - http://www.mouser.com/ds/2/307/en-g5v_2-536510.pdf

What pins do i need to use on my relay -- related to the one in post 24? They are different numbers--i believe on mine the coil is pin 1 /16 --im just lost as to which 3 i need on my relay. Do i need a ground for this circuit or relay ?

i am not using a toggle switch or LED's

Yes, remove the lo jack.

Ignore the pin numbering in the pdf datasheet. Use the drawing in post 41

[Valvehead]

thats why im lost , there are no pins labeled 3 or 5 on my relay

it has 1 - 16 - 4-6-8 9-11-13
