In the world of recycling and being green an all that, could you:

 Get an old avant that somebody will pay you just to take it away 'coz it ain't full hd (yawn) get it home, extract the active pair of loudspeakers (that are apparantly a cross of Beolab 2500/ BeoLab4000), make a nice little box for them, then solder a powerlink connection & mains power and bob's your uncle use them as 2 reasonably powerful B&O surround speakers that would work great with my BV3?!

 Or is it impossible? :(

Or do I stick to my original plan which is even more difficult....

I have no idea but I like the way your thinking, very innovative - good luck anyway as you keep coming across these 'uneconomical to repair' Avants now.

I have wondered about this too.

Any older Avant that has a blown tube is probably headed toward a skip as the tube would cost so much more than the TV would be worth, but the Audio system must be worth saving.

 Hopefully someone more expert than me will be along in a minute!

Great idea.

And following on from this, can someone please confirm whether the speakers in the 32" varient is the same as those in the 28"?

Thanks

I would say this would be a viable project provided you have the 32" VCR version (28" is a little different)

Below is a block diagram and as you can see it only uses +/- 20 volts, so you could use a seperate power supply, using the AVANT power supply maybe somewhat difficult. But module 10 & 11 are the key parts and they would be easy to remove an use.

I did it but was unable to start up the original power supply PCB from the Avant. That's why I made my own +/-20V power supply which is switched on and off by a MOSfet (low current drain) and some other components. I implemented this speaker system in my BV5/Beosystem 3 combination as the center speaker.

Works great but slightly lower ouput then my BL3/BL8000 surround speakers. This could be tuned in the sound menu.

Would it be possible to use the Dolby Digital card from Avant with 3rd. party TV.

I think it would be possible with a few small modifications..

More interesting project: Leave the Avant with the blown tube intact below the shoulders and take the tube out. Replace it with the appropriate size LCD monitor. I'd really be interested in seeing this!

I'm also waiting for someone to empty out the gorgeous BeoVision 5 and give it proper HD guts! It seems fairly easy considering how the plasma is mounted inside.
