Hi,

My proposed new home for my SB2 arrived yesterday.

Some pictures here:

It's a dead Cambridge Audio DACMagic 1!

I've not powered it up yet but it apparently blows fuses when switched on.

I've not finalised my plans yet, but I'll probably do some or all of the
following:

- replace front panel and mount SB2 VFD in centre
- power the SB2 from one or more of the existing power supplies
- replace the SB2 digital supply with a Super Regulator
- Bypass the SB2 output stage (drive direct from DAC)
- Use the DACMagic output stage, including balanced outputs
- upgrade the DACmagic analogue stage (caps, opamps, etc.)
- Power which ever analogue stage I use with a SuperReg
- connect up the digital inputs to the SB2 DAC for use with other sources.
- connect the pretty lights to the SB2 DAC some how :)

I'm waiting for a Service Manual for the DACMagic so I can work out how
to hack the circuit but I've drawn a blank so far. If anyone's got one
I'd appreciate a copy.

What do you think? Maybe slimdevices should consider making something in
a box like this?

Cheers,

R.

Hi Robin,
this is a very good idea to re-cycle some of my DACMagic II !
I suggest you to replace all three transformer, they are not very reliable.
If you remove the tape around the tranfo you fill a little fuse or thermistor, you may try to replace them but in my case I prefer to replace them all.
One two of my unit I replace the all the 10 filtering capacitors.
Some of them was starting to leak.
I got the service manual if that help.
I'm leaving in Montreal,Canada.
I guess I could scan it.

Hi,

If you can find time, I would very much appreciate a copy of the service
manual - a scan would be great!

Thanks,

R.

Hi Robin,
I scanned the service manual for the DacMagic but I'm unable to upload the pdf to this forum.
(the size of the zip. file is about 12M)

Please provide a location where I could put the file.
PS: I got accces to my company FTP site, send me a private e-mail if you to use this option.
