Wow, that is superb both on quality of construction and beauty. Nicely done. What case is that?

Hi orthoefer,

thanks for your comment. The case was built by a member of another forum who tried to mimic the classic Naim cases to provide better visual integration of DIY efforts. ;-) At one point he sold them on eBay.

The inner chassis is made of alloy, the outer case is made of perspex. I added the separators for the toroid and the passive pre, heat sink, plugs, etc.

Actually, this is my 3rd GC, and I wanted to build something more ... erm... definitive, if you catch my drift.

Best,
Oliver

Just a quickie before I take some more shots of the innards, but here is my latest "finished" amp built inside of an old SCSI external enclosure. Those babys are GOLDEN for compact chipamps, and you can usually find them surplus for dirt cheap or free. Get busy with the cutting wheel and dremel, slap on a new coat of paint, and you have a great, roomy enclosure.

I still have to add power lights on the front (which is 3/16" aluminum plate) and get some better feet, but the guts are done. I am planning on using this as an office amp for my iPod and computer, so there is no need for volume control since all of the devices I will be using with it will have volume controls built in.

More pictures of the guts of my amp. This thing isn't what I would call "good" with regard to wiring or layout, but hum is non-existant and the sound quality is excellent. It's a dual mono due to a great deal on 80VA transformers at ApexJr that I couldn't pass up (who are great to deal with, btw). Hidden under the torroids are 2X2200uf/rail (250V!!!) caps that were salvaged that I had laying around (4400uf X 4 rails total). They take up a ton of space, but work great with this configuration.
