Help with relay board

Post by mat »

I just went back to my unfinished 'EF-86 Special' build after over a year and cannot find a part layout (or from whom I bought the board) for the relay board.

I was hoping to power the board from heater taps (the trafo has heater centertap that connects to the cathodes of the EL84 pair)

Does this pic ring any bells?

Hi again Jeff :D

Been lurking and building a pair of EF86 overdrive pedals. Now I'm back to: http://www.flickr.com/photos/fuzzface19 ... 976903558/

Feels like have to learn everything from the beginning :lol:

Clips asap (if) the build will (ever) be ready :roll:

I might have to power the pedal leds with a 9V battery. Any errors/suggestions for my schem ? http://www.flickr.com/photos/fuzzface1966/9030339723/

On Brown Note schem at http://www.brownnote.net/forum/download ... &mode=view I see no regulator.

Thanks for any advice,
mat

Mat,

Your drawing looks fine to me.

We figured out how to light the LED's on the foot switching on the Hoffman forum.

There may be something useful about the relays in this thread which has multiple pics, drawings etc about installing relays & ft switching etc...

They look so pretty without a mess of wires don't they? :wink:

Here is my 9V regulated supply for a dumbleator (designed to fit in a ceriatone rack case). Powered by a Xicon TX
