D'Lite Relay Question

[doveman]

Currently I have a D'Lite 22/33 (loaded with 6L6s) that I loaded TWO relays in a few years ago. One relay switches on the OD/CLEAN while the other initiates the PAB. At the same time, this 2nd relay switches 1/2 of the BASS MOD. In other words, when PAB is on = NO BASS MOD and when PAB is off a 100k resistor is engaged off the right lug of the bass pot. I like everything about the amp but the cleans are better with the bright switch on when the OD is off. I don't want to change anything else.

I still have the third relay that I did not install. So my question ... Can I install this third relay and connect it so that the BRIGHT switch turns on when the OD is switched off ... using the single footswitch button?

The short answer is yes, but you will have to be mindful of your lead dress. The wiper is quite a sensitive part of the amp.

Would it be better to have a three button footswitch and wire it up that way? Bright switch on it's own relay?

Hey Ken, what you want is called the Bright on Clean mod.

It will take another relay to do it.

You don't need a footswitch for it you just use a On-Off-On toggle and install it in your bright switch hole.

Down position is bright off, middle is bright on for OD and clean and up is bright on clean only.

I have this on my D'lite and 100w ODS clone, I like it a lot because it really adds some snap to the clean channel.

I believe I have a 120pf silver mica on mine.

That looks like exactly what I was asking for ... thanks. I need to get some time to do it. Not critical but nice to know what the option is.

Thanks for chiming in Tom. I had a look at his relay wiring and it does look different to various circuits layouts here.

Mine's a D'Lite rather than an Dumble as shown. There are a few wiring options that are available as discussed here and on the Brown Note site. But what I'm considering is the option to switch the BRIGHT/OFF switch at the same time the CLEAN/OD is switched.

I'm thinking that if I reconcile the two this is a solution. Sounds like Tom has done it on both his ODS and BN amps. I'm pretty sure my 1/2 BASS MOD is the one Tom used, as well.

Hey Tom ... do you already have a drawing for this on the Brown Note switches BRIGHT - OD - PAB rather than ODS version?

All helpful ... thanks.

[Structo]

No but all you need to see is how the bright switch is wired.

Take a wire from the negative side of the OD relay power, run that to the bottom of the three way bright switch.

Take another wire from the negative of the Bright on Clean relay and run that to the middle lug on the bright switch.

Run a wire from the top lug of the bright switch to the ground buss wire.

Connect the positive on the Bright on Clean relay to the other + on the other relays.

Now anytime the OD relay is powered on and the bright switch is in the middle or up position, the bright relay will power on connecting the bright cap.

I have a 120pf silver mica, anything above that was too bright for me.
Experiment.

I like it because when I play my neck humbucker in clean, that bright cap adds just the right amount of snap and chime to the tone.

If you don't have room to have another relay board in line you can stack the relay board on top of the OD relay.

Just use the appropriate height spacers and longer screws.

When the bright switch is down, bright is off.

When in middle position bright is on for both OD and clean.

When the switch is up, it is bright on clean only.

[Structo]

This is how I have mine.

[doveman]

I would have never thought to stack them ... but that's simple and effective. Thanks. I think I'll be able to figure this out now.

[doveman]

OK - I checked and i have enough room to stack the remaining relay on top of the existing relays:

1 - First connection (light black lines) shows the connection to the ON-OFF-ON switch allowing BRIGHT (on clean only) - BRIGHT (all the time) - BRIGHT (off)

2 - Second connection (light colored wide lines) show hooking in the existing bright cap ( I like the existing value - 270pf I believe)and volume control

3 - Third connections (black wide lines) show connections to the B+ and ground - there are several options.

don't have the front panel lights or that whole scheme to the right. But this is what my relays look like.

What do you guys think?

Ken,
You need the bright cap to connect to the common and the NC, normally closed.

It will work the opposite of want you want if you connect it to the NO, normally open.

OK so ... COM<---cap--->NC at the top or the relay instead of COM<---cap--->NO (the way I have it drawn). Everything else looks ok?

Thanks!

[Structo]

Yep, common - cap - wiper of volume pot.

wire from normally closed NC - to right lug of volume pot.

You da man! I might be able to try this sometime this week.
