Relay Supply

[Structo]

Why do you suppose HAD ran two B+ wires (red) to the relays instead of just one then jumpering to the other relay?

There has to be a reason.

Ya always wondered that too.

I jumper (parallel) the V+ to the second relay.

Why 2 wires to the footswitch jack too?

Every late gen ODS amp I've seen pics of (including #155), has had one +12V lead going to the channel relay where a jumper, as you've suggested, connects to the PAB relay.

#124 is the only one I've seen running two 12V wires to power the relays.

Tom,

Since you are talking switching, have you got your footswitch yet? I have been using those Marshall knockoffs from AES but the wire and resistors in them is junk. If you are going to get one of those, I recommend replacing the wire.

[Structo]

Yeah I used one of those AES two button footswitches with my D'lite.

I'll get the generic three switch one for the 100w that I'm building now.

I have some six conductor shielded cable that works well for the pedal cable.

[Structo]

I decided against the 150ma transformer, just too small.

I picked up an Allied Electronics 6K212HF
Pri: 117v, Sec: 12v @ 1.2 Amps

It's a bit larger than what is normally used so I'll have to shoe horn it in but I will have peace of mind about the current.

I used a MIDI cable on one of mine because I have a bunch lying around. Worked well.

I use this to run a solid state reverb and my channel switching (8 volts and 5 V relays in series with LED's) on my mods...and never had one die..Warm to the touch, and cheap. 1.2 -A ?!?!? If you are adding DC filaments, sure. For relays....extreme.

[Structo]

Wow $2?

That is cheap!

The only reason I will use this one is because of the availability of it.
Who knows I may end up using something else by the time I get to installing it.

[FUCHSAUDIO]

I bought a butt-load....easier than trying to adapt every different mod platform to drive relays etc.... small, cheap, and effective. Watch, H&R will sell out, and I'll lose out..

[Structo]

I got that three button footswitch from AES today.

I must have been asleep when I looked at the diagram before.

It only has a four conductor cable.......
Oh well, I'll have to get more of the cable I used on my other one.

[dimitris]

No need to do that Tom.You can operate three switches and their leds with a four conductor cable.Check Mdroberts BM Schematic:

[Structo]

Cool, thanks I had not seen that before.

I'll have to give it a try. Looks like I still need to redo the wiring to the switches as it doesn't look like it is hooked up like the Dumble.
