What happens when you take that resister and cap out of the loop. I am like you mcinku, I had some electronics training but I have to start over, it's all good though, I enjoy everything about music including this.
As far as I know that resistor and cap will do nothing if that jumper wire is there. It is the same as you would have a patch cable plugged in the loop.  |

So is the current layout incorrect? I'd like to know before i get to that stage.
Thanks

Correct is a relative term... ...if you are after #124 than it's wrong, if you're after D'Lite style amp or many other D style amps I've seen than it's OK, except lose that resistor and cap, it's not needed. the rest of the layout is fine |

mcinku What exactly does that jumper wire do. I am trying to learn all I can but I really feel ignorant sometimes. The other thing is how much change is there from #124, which is 100 watts. And how do I optimize this amp to run el34's..man I have a long way to go in understanding all of this. How is it going for you. Burnie   About the jumper wire some info here... http://ceriatoneforum.com/index.php?topic=207.0...basically it takes out that loop network (resistor and cap), so why put those in, if the jumper wire is there  I'm learning as well. Most of the stuff about ODS style amps, I learned at Amp Garage forum. Those guys there are quite intimidating, so some electrical knowledge is almost a must. I at least have some... but a lot is lost since high school.  |

Nice review. Great playing
I wish you had posted some clips with a guitar with single coils though.
How clean is the clean channel? There';s some break up in your tone there. I realise that's what you want but for me it's importanmt that the clean channel remains clean at "high" volume.
As you can see his master volume is at 10, that's why his clean tone is breaking up. |

As far as I can see Nik has changed the OD level pot to 100K and pre OD resistor from 150K to 220K. Exactly what I'm planing to do with mine OT  . That jumper wire on the loop is still there. Everything else looks the same as far as I can tell. |

This sounds like a bad relay coil to me .... or maybe there is no power to the relay... Does your PAB switch work? If not, it could be that your 7812 went bad or even something with the relay power circuit. A good tech should have this fixed in a few minutes. |

Can you hear a relay click when you switch the amp off? 1. Power the amp 2. Select Clean ch 3. Power off the amp (leave the standby switch on) 4. While the big caps discharge you should hear the relay click That would prove that relay is still alive but it doesn't mean relay is OK, the inside connectors could be bad. Like I said just thinking here |

mcinku, Off topic: I must fess up and say that I am the one who hath smite you. It was a total accident. My sincerest apologies.  Really , man I don't even remember that. Are you sure you have the right man. |

Can you maybe change the V1 tube... maybe swap it with the OD (V2) If your clean ch would be dead I think your OD ch would not work either. Do you know how to measure your plate voltage on the V1 tube? ...or maybe there's something wrong with your OD relay . I'm not a tech, just thinking what I would check first.  |
