Are there custom build Hi-Fi people out there?
Discussion
Would it be possible/viable to extract the rather lovely sounding amp components from my old Yamaha micro system, and have them turned into a standalone amp?
I know it sounds sacreligious to wreck old, good gear but I don't use the built in twin casette deck, barely ever use the CD player nor the radio. The poor thing is threatened regularly with getting disposed of, for a micro system it's still pretty big and takes up a lot of space, yet I'd love have the useful bits inside turned into something more minimal.
I don't think I'd have a hope of doing it myself, I wonder if there are electronics or hi-fi engineers who do this sort of thing for a living?

Very unlikely I'm afraid. Microsystems made by the 'better' brands ( Yamaha, Denon, TEAC, Yamaha ) are usually well engineered with custom metal bracketry + custom heatsinks and wiring looms. The casing will also have specific ventilation holes to keep everything from overheating.
Isolating the amp section only will involve transplanting the power supply and amplifier stages into another appropriately sized case along with associated on/off switches, remote control receivers, output socketry etc etc. It can be done but many standard cases might not be much smaller than the current Yamaha's.
Here's a typical case https://enclosures4u.com/2u-19-inch-rack-enclosure...
The labour involved ?? I'd be surprised if it was under 3 hours, particularly with the various holes which will need to be cut in the case. Estimate £125-£150 total.........you would also have to satisfy yourself that the modifier understood the safety implications of making these changes too.

Commercial products have to undergo various EMC and safety checks to 'earn' the CE/UL type approvals. Products need these approvals before they can legally be put into put into the public domain.
If the unit is to fit on a bedside table, I presume you're already considered products similar to this http://www.currys.co.uk/gbuk/audio/hi-fi-speaker-d...

Aha, so there's a compliance/safety reasons why not, hadn't thought of that. Although, having a look around "custome hi fi encolsures" after the the link posted above, there appears to be plenty of self building going on, which either means CE certification is simple, or people don't bother on one offs.If the unit is to fit on a bedside table, I presume you're already considered products similar to this http://www.currys.co.uk/gbuk/audio/hi-fi-speaker-d...
Safety is obviously a concern, this is one of the reasons I don't want to attempt it myself as I'm sure I'd inadvertantly solder a live feed to the aluminium chassis.
AlsoI'm not looking for an alternative, I may be sentimental but I'd like to recycle the useful bits of this hi-fi that is currently in working order, albeit somewhat obsolete in its current form.
Get yourself a little t-amp and build a box for it. Or maybe someone already makes a nice box for them? I understand that you'd like to recycle what you has, but I doubt a Yamaha micro system is going to be worth the effort.

Interesting you say that. It's a YST c11, single unit, which is pretty large (c. 30x30x23cm) and about 8 kilos. 24 watts per channel.
It powers active servo speakers, which i guess complicates things further.
Obviously adding a dock is perhaps an unnecessary addition, but i am pretty surprised people din't do this more often. I guess it's too complex and expensive to attempt this sort of thing (plus add the certification element).
One of the reasons I thought of this was that I've also got a Teac surround sound system which the seperate 3 channel power amp is a Tripath with super sound quality and very often tweaked and modded into new boxes. I supposed as it's a seperate, only doing one job, this is much easier to do.

Active speaker tends to suggest the actual amp stage is in the speaker. In turn suggesting that your 'amp' is in fact a pre-amp.
If what you are suggesting is possible, I suspect it still wouldn't work unless paired with the Yamaha speakers
Brilliantly engineered and tragically under rated stuff is Yamaha IMHO. The Honda of the HiFi world.

I don't think it's quite as simple as that - reading about YST, the speaker provides feedback to the amp which then controls output to optimise bass, volume etc. It's certainly proprietary and you can't fit any old speaker to the amp.If what you are suggesting is possible, I suspect it still wouldn't work unless paired with the Yamaha speakers

Certainly given the size of the speaker it does generate a lot of clear, loud sound across the range. This is why I bought it in the first place. The speakers also fire out puffs of air from a forward facing port you can feel from a few feet away, which is nice
To oput this all into new enclosures would be great, buit given the feedback from here, I'm not sure if this is possible now.
