Squeezebox SB3

Posted 10th October 2010 at 01:00 AM by audi0

After much deliberation I've decided to 'jump in' and modify my Squeezebox SB3.
I have read many threads on this and other sites gaining lots of ideas of what I want to try to achieve, basically as follows:

improved power supply, dump the wall wart and build a linear supply 5V @~ 3amps
improve the analogue section, initially trying different op amps and upgrading capacitors
remove the inductors from the digital out, add 75 coax and BNC connector (maybe add a transformer?)
upgrade to the 3.3V supply to the clock
build a new enclosure similar to a Peter Daniel amp, chunky aluminium back and front with timber sides (copying is the greatest form of flattery!)

I have made a start, opened it up and discarded the old plastic box. De-soldered the connection board and set aside, then soldered temporary wires for power L & R out and ground back to the connection board (temporary connection)

To get the board into the proposed enclosure, I had planned to remove the display screen completely and install it remotely via ribbon cable. On closer examination I found that all the connections are along one edge of the display so that if I could free it I could turn it through 90 degrees.
If you are attempting this, be very careful cutting the D/S tape holding the screen in place! I used a very sharp scalpel blade and carefully worked through the centre of the tape, the tape has a very aggressive adhesive on it and is near impossible to remove, so I left it on there.
The connection pins are very fragile, so one bend is all that I would attempt, I held the display in place with 5 minute epoxy
I nervously plugged it in, hey presto it still works (for now at least!)

I am now getting parts together for the power supply and analogue upgrade, I'll update when something starts to happen.
