Relay switching?

[Tdale]

basically what I'm wondernig about is if th relay should be wired like the dpdt switch in the schematics?

The way bob explained it, it looked like only one half of the switch was used...

No, the other half is used for grounding.

[Tdale]

Ok..sounds reasonable.. The way most schematics are wired, the od doesn't get grounded when it's not used..

How is the other side connected to make the grounding?

Every relay is different as far as which leads are connected when the switch is open and closed. The schematic Illustrates 2 poles and 2 "throws" you have to figure out the way your mechanism is wired.

[Tdale]

Looks like the switching is done in several ways...

this is how I concidered doing it...but that's maybe not the best way to do it...

On the NTE relays the Poles are the lower tabs, so what you have there won't work. There is no "Blanket" way you have to look at it as what connects to what in each mode and not as a "Paint by numbers" that's why I said get your relay, test clips (Alligator leads) DMM, and a battery and see how your relay works.

[Tdale]

I understand that, and I'm able to connect the relay correctly, as long as I know how it's configured.

The link I posted is to a standard dtdp switch, with the middle lugs as commons.

I'm wondering if that would work fine as it's shown there? If it does, it should work on a relay too, as long as the right lugs are connected, so it works the same way as the switch in my link..

first of all, are you going to have a separate master and post OD stack or are you going to have a global master? that will make a difference in how you wire the relay.

[Tdale]

The plan was to have a global master, and no post OD stack.

But I checked the skyline schematics, and I kind of like the clean master, and might want to go for that.

Could it work with both the clean master and a global master? I suppose I'd end up with two masters in the clean mode....

The OD input [b][i][u]MUST [/b]be grounded. Hope the drawing helps.

OK, Let's talk about a NON HRM amp.


You have 2 "Poles" on your Relay, we'll call them L and R

You have 4 "Throws" on your relay, we'll call them L1,L2,R1, and R2

L1 and R1 are the "Default" un-powered mode of the relay

L connects to the outside lug of the master, L1 connects to the output of the .047 coupling cap as well as R2. L2 connects to the output of the overdrive circuit which is the center wiper of the 100K OD Volume pot(Ratio).

R connects to the input of the overdrive circuit. R1 is grounded, R2 is connected to L1.

[Tdale]

Looks fine... But where is the input to the PI tube connected? Or is the master volume connected between the relay and the PI tube?`

I don't understand what HRM is..maybe that's the reason?

Yes it does. I made the exact same drawing, looking at the skyliner schematic... I guess that's the way to do it, either you use a switch or a relay.

Why does the switching need to be different if it's a HRM amp?
