Not Sure Where All the Wires Go...

Hello All, This may not be a CBG for this group, but I didn't get much from the other appropriate group. I came across a circuit board and speaker from a Fender Mini Amp. I thought I could just wire…Continue

Rattle and Less Hum

Started by Gordon Cooper. Last reply by Wayfinder Jun 2. 16 Replies

There's a lot of 60 Hz hum in my acoustic/electric dulcitar. The amp runs on a battery, so there's no wall-wart leakage, at least not directly. Besides wearing a wrist-mount grounding strap that…Continue

Pete, to post pics use the little blue box, upper left corner, right next to the LINK.

Ok. Not sure how to post the pics here. I can email them to you

Simon I've had some success with a variant of this circuit. Based on the Little Gem. I use a witchcraft input jack. So when you plug in the guitar the circuit is complete. Un plug and it shuts down. No battery drain and no switch required. Although adding a switch can increase the cool factor. I'll post some pics of my circuit and wiring lay out.

Thanks guys, from the sounds of it I've wired it up right, my SW1 is a dpdt on-on so I've ordered an on-off-on off eBay. (I haven't got a day off to go and get a replacement this week and there's no electronics shop in town) I've ordered a new LM386 too just in case there's a fault in mine so I think I'm going to strip it all down and try again. If there's no mistakes in the schematic I can't imagine what the problem could be.

The down pointing larger triangles should be connected together, this is the "common" or ground.

The up pointing smaller triangles should be connected together, this is the "power" or +9v to the circuit.

The switch SW1 should be a double pole double throw center off switch (also called a on-off-on switch). As drawn when in the up position, power is turned on and the audio output is connected to the earphone jack. When in the down position, power is turned on and the audio output is connected to the speaker. In the center or off position, power is turned off and the audio output is not connected.

The 10k pot R2 is the volume control.

Give it a try like that and let us know if it works.

That bottom right of the schematic shows a switch for what looks like choice of battery or walwart and should have a middle leg diverting power to the circuit at the top going to led, caps and pin 6. 

We need to see what Simon has done on the board though to troubleshoot his board.

Comment by Graham on May 28, 2016 at 3:41pm

OK looking at that circuit, the LED will always come on. To make it switch off add a simple spst switch from the + on the battery to SW1.

R2 pot is the volume control.

Comment by Paul Craig on May 28, 2016 at 2:42pm

I though it meant up too til I saw the grounded circuits looked the same.

A good pic of the top and bottom would be helpful.

Comment by Simon Cartlidge on May 28, 2016 at 2:40pm
I took the little upwards arrows as matching up so put the positive from the battery to pin 6. My board probably looks even more confusing as I have a lot of things off board, I'll try show my setup.
Comment by Paul Craig on May 28, 2016 at 1:51pm

Looking at the schematic is a little confusing. I t has the battery in part down by the amps output to speaker and show the pin 6 to go to ground(little triangle) when the battery + should be going to that pin. Should be a on off switch right after the battery before the led Circuit.

Can you take a pic of your circuit board?
