Chip Amp Photo Gallery

Here's a link to a MyRef Fremen Edition compact build. Had constructed a wooden frame for shipping that disintegrated and this is the recovery.

One of my creations

A few photo's of one of my Gainclones, based on the very nice boards from Peter Daniel.

The PSU has his own enclosure, is very standard and not ineresting to show.

I build this one about a year ago and its very often in use. The performance is great.

The VU-meters are not working. Don't ask me why, but i quit working on them. Only for the show.......

The goal was to make the amp as small as possible. The enclosure is 10 cm wide, 6 cm high and the depth is 167,5 cm.

The heatsink is a plate off aluminium and is big enough.

STK-402 aka The StackAmp

I needed a small amplifier for desktop/workspace use so I decided to build one using only salvaged parts. The STK 402-040 hybrid module came from a junked stereoset, heavily trashed but the main board was intact. The rest is a gathering of junkbox items, Intel stock cooler, transformer and volume pot from a cassettedeck, powercaps from a blown dynacord 19 inch rack amp and a nice piece of old mahogany plywood.
I used the standard application note schematic which performs excellent, this little thing rocks with good, clean and undistorted sound. I really like it and this amp is now in daily use.

Kudos doctorzorro. Very unique and interesting design. Clever re-purposing of used parts. I like the tower concept.

Thanks davy, it has been a fun process. The small power supply you observed is an amb switch driver for the lighted momentary switch. I would highly recommend this setup for anyone having any "switch bounce" issues. This also separates the mains power from the power switch via a relay. Also you get to use a cool looking lighted switch; I went with an amber switch to go with the copper. Plus the amber was cheaper.....my guess not as popular as the other colors.:D
 
Thanks Will, I was wondering why you had another PSU in there.

No hum issues here now, even using my CDP and with the FE's PGND to chassis links disconnected. Worth trying with yours if you get no hum. Rewiring my amps, using a heavier mains earth wire and using the DCB1 as a proper pre/controller did for most of it and a new transformer finished the job.
