This is the fabled pre amp accessory for Beomaster 6500/7000 receivers. Part Number 8001245

Removed from a working installation.

Will enable you to connect your existing Beogram 3000, 3300, 5005, 5500 or 9000 to a the newer 6500/7000 Beomasters without requiring a stand alone pre amp with all the associated problem cabling.

These devices are as rare as rocking horse droppings! I have never seen one before.

Requires soldering to existing holes in the pre amp board and two links cutting.

Currently for sale on ebay at a silly price but available from me to Beoworld members at £90 plus postage at cost.

Please send me a message or email if you are  interested.


Regards Graham

Wouahh it does exist!

Can we use it for the Beomaster 3500/4500?

Does someone heard the same good story for Beomaster 3500/4500 equipment, I would, as many others I guess, be very interested.

The board for this has a known part reference 800 29 56.

The circuit diagram and the layout can be found in the BM 4500 service documentation.

 

Thank you for the feedback

Great so it does exist fror BM 3500 as well!

"Silly" question: can you source more than one RIAA?

An other one: did you ever think of duplicating this board?

There was one for sale on ebay.co.uk quite recently. It didn't sell, as far as I recall.

Technically speaking this would be a rather easy one.

Legally speaking, that's another story. I think that you are allowed to publish schematics after 30 years but copying - I frankly don't know.

And the BM6500 isn't 30 yet.

But for myself I was thinking about it until I got a used defective RIAA for fitting directly into my BG3300 turntablewhere there was enough space (and as it's the same chassis as others with the built-in RIAA).

I once thought about building this one for myself as well but didn't have a readable layout.

Yes - but the one for the 3500/4500 is not the same as the one on those Pictures.

The RIAA amp for the 4500 is a module with 3 DIN sockets. (PH+2 PowerLinks). 
My dealer mounted a module in my BM 4500 back in the 90's. Cost: 500 DKKr (approx. 70€)

Finally I was lucky enough to find a RIAA module which I installed in the 3500. 

It 's a matter of swap with an already installed. The preamp is very good and now I may link to any TT.
