That looks great. I love the clear case.

I've been wanting to build a Cmoy that uses a TLE2426 railsplitter so this seemed like a great place to start. I used the PCB design by guzzler and modified it slightly. I added a diode and an LED on the board. These two items make the powersupply section look like a MINT (my next project). I...

I've been planning to build one just like this and just might use your PCB. I notice that R4 and R5 are jumpered. Why? Also, what are the values on the other resistors? Does this follow the standard CMOY resistors? Thanks for the great post Guzzler.

Thats a pretty tall order if you don't really have a workshop or access to the proper tools. You will most likely have to buy an off the shelf enclosure, Lansing Enclosure model GrayBox style A in black, and then modify it to you specs. It will take a bit of work but it can be done. the link...

You might try a cold cathode tube to light the entire case. They are often used in computer case modding and can be found locally at CompUSA or Bestbuy. However, the DC/DC converter and tube might emit noise that could get in to the audio. They are cheap, $15 US, so it might be worth a try.

Your soldering looks a little rough. It looks like you might have a few solder bridges between traces. Make sure nothing is touching that shouldn,t be.

Thanks guys. They were fun to build and let me get some practice on wiring and panel layouts before I attempt to build a PPA.

How do you test an op-amp for oscillation and what are the symptoms of an op-amp that is oscillating? Also, if it is a two channel op-amp can you get oscillation on just one channel?

We've used their parts at work for years and haven't had any problems. I would recommend them.

I have to second JMT's post. The Unibit is THE way to go. It works great in wood also. They are a little pricey $17-36 US dollars depending on what range you get, but well worth the money.

Here are some pictures of the two Clones that I built. I tried to keep them as close to authentic as I could. I made my own circuit boards and poplulated them with Solen Caps, NJM-4556 op-amp, Vishay resistors, RS-Alps Pot 100k, I also used Neutrik 1/4" jacks. The boxes are old cigar boxes a...

I like the regular jack. It gives a much cleaner and classier look. Not nearly as cluttered.

You gotta love the picture with the glowing LEDs. It makes you want to put a clear top on your PPA.
