Hi,

I solved the flutter issue by re-positionning the REC-PB head. It was not perfectly aligned with the cassette bodies!

Alas no. These seem to be as rare as hens' teeth!

I forgot to mention that my Beocord 2200 (BTW, remember that switch, Martin?) makes tapes that are fully compatible with the BC 9000 both ways! Ditto with my BC 8000.

Is it a problem with the Naks (I've got two, similarly aligned to factory specs)?

I suppose you don't have the tape originally supplied with the Beocord ?

Thanks Martin.

It is indeed flutter. I have no wow at all. I have just noticed the rec/replay head is not perfectly at right angles to the cassette. Is this normal on this deck? The erase head is. Also a tape recorded on the BC 9000 sounds identical to the original when replayed (I am impressed by the hiss level of the BC 9000, it is so silent!).It sounds overbright on my Nakamichis, but azimuth is correct. Reversely, the tapes made on the Naks sound dull on the BC but of course fine on the Naks.

Pre-recordeds sound dull on the BC but correct on the Naks.

Jacques, just to prevent misunderstandings:

Flutter is variations in amplitude (usually tape/tapehead contact related).
Wow is variations in frequency (usually tape speed related).

Sounds like you have wow rather than flutter since you suspect the motor etc.

Beocord 9000 flutter [solved]

Hello everyone!

I have a very good condition Beocord 9000 with fine electronics. It calibrates fine too.
My problem is in the transport.
The belt is new. There's some flutter left, noticeable on piano notes mainly, I can't get rid of. Wow seems in good order. The felt brakes are clean. Motor lubrication? It is not very noisy though!
Is it possible to lubricate the motor inside? I successfully did it on my Beocord 2200, but the motor was designed to be dismantled easily.
The mechanism is not very silent when playing, you can hear some friction. Hardened idler tyres?
Do you know of any sources for these? The smaller one in the idler hub seems impossible to source especially.
What do you think?
Thanks in advance for your advice!

Jacques
