FS: Maxed Out CMoy with Modified Linkwitz Crossfeed

post #1 of 36
Thread Starter 
I'm selling my best looking amp that I own to upgrade in the portable area. I need new parts, but anyway, the amp is a CMoy design, gain of 11.
Other specs:
Opamp installed currently is the OPA2227PA, but I can also send you an OPA2132 for no charge as I got it through the TI sample program. The audio jacks are the nice ones on Tangent's page, which have a much better build quality than the regular Switchcraft ones. There is no humming or buzzing, and I have been using this amp for almost a year now with no troubles. The battery life is fairly long, and I'm actually about 3 weeks into the latest battery, using it for maybe 1 hour a day. Enough description and I'll show you some pictures.






These pictures were taken in May, but there has been no physical change to the amp since then except for a minor scuff on the battery compartment door.
As for the pricing, I'm asking for $65 plus whatever shipping comes out to be, as the build quality is very good, and because of the extra crossfeed filter added on. I've spent a long time on the casework of this amp, making the appearance as clean as possible. If you have any other questions about function, or if you'd like me to take more pictures, just PM and I'd be happy to oblige. I'd much rather sell to my Head-Fi brethren than on EBay, and I know that this amp will possibly help someone break into the world of Head-Fi.

Thanks,
bperboy

Hmm. random musing probably isn't wished on this forum, so go ahead and delete if needed.
Thanks for the comment, and I hope you very much enjoy your own DIY adventures! For me, even through all the troubleshooting, it has been very rewarding.

Is this a portable amp? I mean, is it small?

This CMoy is designed as a portable amp, although the case is a little on the large size. It is a just a little longer, wider, and taller than my iPod. The actual dimensions of the case are: 5.310 in. long x 1.500 in. tall x 3.350 in. wide. It is hard to fit in your pocket, unless you have a cargo pocket.

Some interest so far, but nothing solid. This great amp is still up for sale!

Had a potential sale, but buyer backed out. This amp is still up on the market, and you know you want to give yourself an early Xmas present!

Could you put up a pic of it comparing its size to something?
