The Amp Garage

Thanks for reply.... I know of those, but aren't they rather flimsy for a pedal? Anyone really used those for pedals?

I'm looking for a sloped blank box that could house 4-5 switches.... without buying a original Fender or Marshal pedal....
Any tips??

I'm working on a ODS clone, - but on a more general basis, - what's your opinions on HV fuses?

Well, thanks guys.. I know of all those gizmos.... Somehow I thought about a dtachable subpanel from the inside, fixed to the main front with carriage bolts, but probably making it unnecessearly complicated... Grill cloth directly on the front panel or on a separate frame??

Maybe a silly question, - but not for me.... 8) Over the years I've built several hifi and PA speakers, and in most cases bolting the speakers to the cab is easy-peasy... Now I'm about to start amp and speaker cab for a project I'm doing, and came to thing of how to attach the speaker to the front p...

That "stripper" seems like a copy of the Ideal Stripmaster that has been around for ages..... What was the price?

Aah.. thanks a lot!!

I may have been dreaming this up, but I'm (quite) sure that I have seen a table ( of sorts) covering variations of component values between versions...
FOr the better of me, I cannot find it..... have I really just been dreaming this up???

Off the top of my head, - try another opamp... try to scope the supply to see where the noise starts... supply, buffer/driver, input driver...
You seem to have very high gain on the neg input to the input buffer....?? How clean is the raw 30V??

Unless you already have som background in electrics or electronics I would strongly suggest that you start with some quick basics in components and simpler circuits. There's plenty of info on the net. from basic texts to online training courses......

Hi Aaron - if you're still around..... and BTW - Happy New Year... I'm working on a copy of the Sonorus, but at the same time I'm working on a schematic that will present the amp as a complete circuit for later use ( when I'm not available... no one in this region has ever seen or heard a Dumble amp...

I bought a chassis from him earlier this year. Very good service and quality, - face- and rear plates included. While I made my own CAD drawings, they needed som correction, - also included.....

In the actual drawing, that diode is only to protect the LED from reverse voltage it cannot handle by itself... At 10-15 mA for a LED any diode can be used, - also 4007....

I'm working on a appx 80W amp....On some occations, I've seen references to a sort of output "safety"resistor, - a 60-70 ohms resistor across the output, as a sort of safeguard against no load situations... what's your thouhgts on this??

That may be a point, but the whole idea of single point ground, otherwise also advocated in pro audio, does not exist in the guitar amps I've seen....
