Thanks for the advice on the speaker.

I have now completed the circuit and am in the process of building the cab. I will post pictures when complete.

My electronics theory is basic. I am very intrigued in the theory behind the circuit, would any one be able to give me a run down of what is going on in the circuit diagram in relation to the resistors and capacitors.

Any help would be much apreciated!

Hi guys,

I got the 'ruby amp' working! I am very pleased with the results. Firstly i would like to say thankyou for your help and advice.

Secondly I was wondering if anyone could advise on a reasonably priced 3 inch speaker. The one i have used is very cheap, and not of great quality!

Once i have a built the cab i shall post some pictures for all to see.

Thanks

Tom

Great, I have been looking at the schematics for the ruby amp and I think i will be Ok with most of it. The only part i think i will struggle with is connecting the 1/4" mono jack socket to the circuit.

Ive tried to attatch the circuit below. My understanding is, there is two connecting prongs on a 1/4" mono jack socket. How do i connect the socket to this circuit.

Many Thanks

Tom

Thanks for the reply. The 'ruby amplifier' looks like an excellent place to start! Sergscar has done an excellent job of making one. I will have a go at making one myself. Il post any pictures of progress or problems i have.

Also could you recommend any jack sockets to use on the project, am i right in saying i require a stereo socket?

The help is very much appreciated. Thankyou.

Hi,
I'm totally new to building guitar amps, and i've challenged myself to building a small portable guitar amp. I have a basic knowledge of electronics, but i was wondering if anybody could direct me on where to start. I would ideally like to design the schematic my self, does anybody know of any usefull books or schematics to have a look at to get an idea of how to approach this project and how to get started.

Any help would be much appreciated.
