Hey Tom this site may help, haven't done it myself (yet) but appears straight forward
Here's a question to illustrate how electronically inept I am...
On schematics like the ones you linked to the "input" is shown as a single line but obviously inputs to an amp ( e.g. outputsfrom a guitar) have 2 wires. What does that single line represent and what does that mean in terms of that second wire. Is the line shown representing positive only or something like that?
Having said all of that, is there a resource for those of us who are that electronically virginal
By this I mean some REALLY basic, entry level, electronics guidance...for idiots?
Hey Tom, 2 wire one active and one ground. The ground is usually the shaft (tehe) of the plug and the active the tip (tehe again). the input of the TC to the tip and out put to the in(put) of the ruby the shaft to ground. Are yoou flying that plane?
Thanks for that.
Is wiring the tone set up for the Ruby amp the same as for the guitar (as those links seem to cater to)? By that I mean can it just be put "in line" before the amp circuitry itself as a kind-of "stand alone" assembly.
Sorry for being so dense it's just that the maker of the amp suggested putting it between one of the capacitors and the volume control and I have no idea why putting it there is the sugestion as opposed to "in-line".... or am I making it too simplistic or muddling things up? I thought putting it before the amp was like having a guitar tone control off-board of the guitar and simply mounted in the amp.
Told you I was an electronics newbie!
You are not being dense I often find it hard to find answers to electronics questions - from my limited knowledge wiring a tone pot like a guitar will give a passive cut of the higher frequencies as you turn the pot control. This can be added to the circuit at the input jack stage and would act in exactly the same way as a control mounted on a guitar.
I suspect if it is suggested to add it in a particular point in the circuit then others have found this to give the best sounding results. Looking on the www the ruby amp with a tone added is called the noisy cricket http://www.beavisaudio.com/projects/NoisyCricket/#NoisyCricketMarkI note the pot value is lower (100k B pot) compared to the typical passive guitar tone control (because it is in an active circuit).
Is this a one off project or are you thinking of building more? The reason I ask is you can probably buy the components cheaper in the UK from Bob at Bits box http://bitsbox.co.uk/
Here is a link to the Data Sheet for the LM386, it may help...
This is a one-off as a practice amp.
I think I'll build it into the amp for the best results. I'll post how I get on.
Oh yes, I was a passenger in the helicopter I am sitting in in my avatar photo.
I WISH I was flying it!!
