I have a nice little CMOY built on a 'Joshatdot' PCB with a larger Panasonic FM cap, ALPS pot, etc. Your choice of 2227, 2132, or 2134 opamp. I apologize for the crappy cell phone pics, but they're all I have right now. $31 shipped if paying via Paypal or $SOLD shipped if paying by USPS money order, in the continental US.




I've managed to track down my camera, so I can take better pics if anybody is interested.

Let me explain the cap placement before anybody asks. The Joshatdot PCB is designed to use a 220uF cap with (I believe) 6mm spacing. I wanted to use a 470uF cap with 10mm spacing, so I had to improvise a bit.

The legs of the cap are each sleeved with a piece of heatshrink then another larger piece of heatshrink is slit for the TLE2426 and then slipped over both legs. So the virtual ground goes through the outer heatshrink, and between the individually wrapped legs of the cap.

The dab of hot glue is just to insulate the legs of the cap where they exit the heatshrink. Probably unnecessary, but better safe than sorry.

This is a great little amp with your choice of opamp; 2227, 2132, or 2134.

Perfect starter amp.

It's built following THIS parts list, for the most part. The output cap has been upgraded to a 470uF 25V Panasonic FM model, LED color changed to orange, and the opamp is decoupled with a pair of Vishay .1uF 50V ceramic caps on the bottom side of the PCB. Not really necessary with the current 2227, but it may be helpful with other opamps.

Gain of 5.54

Need any other info?
