Premium CMOY amplifier kits

stevovee · 10th April 2013, 01:25 AM

I am putting together some CMOY kits with premium parts. High precision metal film resistors, poly film capacitors, alps japanese volume controls and quality pcbs. The kits will include include a detailed instructional video with building instructions. I am using a Tindie Fundraiser to manage the logistics of it. If you are interested please check it out.

Also the kits will include 20, 30 and 50 ohm resistors for the impedance matching on the output allowing for a wide range of headphone impedance values.

With 20ohm output resistors this sounds phenomenal on sennheiser HD600's and HD590 headphones. Volume all the way up still no hissing or noise.

Anyway here is the link to the group buy

Please feel free to ask any questions you may have. I'm usually easiest to reach on twitter at @diyourfaceoff but will also be checking this thread regularly.

is this a group buy?

stevovee · 10th April 2013, 05:20 AM

should I post this somewhere else... It kind of is, Its a tindie fundraiser which only sells if a group of people buy the item. So ten people have to buy it or it doesn't go through. Let me know if i posted this in the wrong place.

No ground plane, ground pours or vias ?

stevovee · 10th April 2013, 08:07 PM

As of now no, but i would like to make these kits as good as possible so I will definitely consider adding this feature to the boards.

I've been looking over these threads on ground planes

PCB Ground planes

Groundside Electrons

and it seems like this is an application where one can get away without using a ground plane. I would like to hear your recommendations on one...do i ground to the signal ground or the power ground?

What would your recommendation be, to add ground pours connected to the signal ground or the power ground?

I've upgraded the kits and reduced the prices. Kits now have ground planes, a TLE2426 rail splitter virtual ground and come pre-assembled in a tin of your choice for $29.99 https://www.tindie.com/products/diyo...amplifier-kit/
