Default B & O 5000 cartridge source?

JH wrote in message
...
My father-in-law's Beogramm 5000 has just suffered a broken stylus.
This is a type MMC 20E, and seems unoptainable apart from an outragiously
priced remanufactured item in the US.

Does anyone know of a reasonable source?

Functional but not aesthetic replacement

Beocenter 2200 , type 2422, 1984
Missing cartridge and stylus, 120 GBP for a new
one which a pensioner was not going to pay.

Replaced with a standard moving magnet cartridge
with elliptical diamond stylus. The cartridge
did not properly sit in its stowage housing because larger .
Also heavier ,Added 25 gram strip of lead to the existing 65
gram. The weighing mechanism at the centre of
the platter needs about 100 gram to register
as an LP, without it, registers as single.
If more anti-skating force is required then
a light spring attached rearwards to the final
lift activation wire , that also doubles , by
deflection as anti-skating corrector.
The rearmost slide bar is the radial tone-arm
posistioner which needs a bit of spiral cable wrap
around the vertical white pillar to reposition the
initial drop position with added cartridge.
The nearer long steel bar rotates slightly
to operate the arm lift. Switch off at mains in
mid play position if required to work on mechanism.
The cartridge stuck to the small socket housing
on the end of the tone arm. 4 turned pin IC socket
pins bent and fitted in the sockets , wired back to
cartridge pins through a small plastic ring
to take up space above the existing cartridge socket housing.
Bit of double sided tape to assist initial
placement of new cartridge.
One small cable tie around all and tightened
and then when finally angled posistioned correctly
lock in place with some dabs of epoxy glue.
Paint black and stow the signal wires to try
and improve the appearance.
