Re: Loud clicking noise

Darrin when you send the preamp of the bad amp to the power amp of the good amp,insert another cable or just a 1/4 plug to the return jack of the bad amp.That way you will break the connection between the preamp and the power amp of the bad amp and you should have sound only from the good amp.

Re: Input jack, new idea ?

You can also use a push pull pot for the treble and use it's switch for the mid boost.

Re: Bluesmaster CLEAN optimized for STRAT (Blackface cap values)

You have a capacitor paralleled with the 100k NFB resistor.What's that for?

Re: Brown Note D'lite owner's help 22/33 or just 22?

I have the 22/33 OT with dual primaries.I believe that it is exact the same size as yours.Mine's code is 8k VIBRO-1 HTS-8815-1 9960750.
I think you can safely use 6l6 tubes,just take care of the speaker impedance mismatch as llemtt has already pointed out.

Re: ODS Footswitch

David this is how i have wired the din jack in my amp for the same footswitch. That way the green wire of the footswitch cable becomes the common ground.Red wire is positive for relay1,white for relay 2 and yellow for the third one. I have wired the switches like heisthl showed in his second diagram...

Re: Relay Supply

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

Thanks Shad for all that info.
Sometime ago it was posted at ceriatone forum that RF's amp has no V2A snubber and V2B coupling cap is 0.01uf .Can anyone confirm if that's really the case?

Re: Preamp out Power amp in OD Special

Tony I never said that your layout was wrong.Original poster was confused with the different schematics and layouts that are floating around and i suggested to look at the actual photos of 124 so he wouldn't have any doubts about the correct wiring of the loop network. I hope that you didn't take th...

Re: Preamp out Power amp in OD Special

Hi Jack
Don't know what Dogears would build but if you study the photos of 124
you will find that with no loop insert the signal bypasses the 220k/250pf pair.
