Hi,

I have just received Jeff's parts, couldn't wait! Thanks Jeff!

Anyway, the PPM now works, as well as the output/rec amp, courtesy of the new MC1437P (actually a double uA709). The spool motor, however, wasn't much better than mine, lubrication being close to zero!

I had a hard time figuring how to put the lid spring back. You have to have the deck in service position because you need to pull the right holder out completely (part n°43, page 4.2) to be able to fit it correctly. It is otherwise impossible.

Now playing Never For Ever on my main system. Superb! Now I just need one in mint condition...

Oh, by the way...

Hi!

The question is: where do the wiring loom sit on the left?

Does my photo show the correct path?

As you can see, my wires are slightly different. There were also physical differences in my broken board from the replacement Jeff sent me.

I think I understand the question. Will check this evening and post a picture.

Jacques, my deck is still open (hoping to go home tonight and find Jeff's board). What exactly is the question?

Well, my pictures were taken when I put the machine back together so the cables etc. may be a bit out of place, I can't remember which cable runs I adjusted before or after each picture..

Actually, on this one I think it was tied up with the two other cables on the left (to clear it out of the way perhaps ??) ? Does this sound reasonable ?

Oh dear, I just dont want to open the beast up again to look where I've put it [:'(]

Hi Jari!

Are you sure the loom linking PC1 to PC2 actually goes where you have it pictured? Doesn't it fool the phones volume wheel?

Silly me, I don't remember where it was!

Hi,

Glad to know Martin's kit has arrived!

I'll probably get them tomorrow then.

My biggest problem is the spool motor. It yells and nothing will do. I'll need a new one. I can hear fine music, no tape eating, but the PPM doesn't light on one channel. All lights are functional.

Oh and the caps need to be changed (the usual red ROE).

By the way, I'd never seen such huge flywheels, even on Revox machines, let alone on Nakamichis!

Going to bed.

Thanks to Martin, my belts are in! Going off to celebrate my wife's birthday tonight, but tomorrow she has to work, and the kids will be going to day care. Looks like tomorrow I'll begin work on my BC 5000 Type 4716!

@jrantala: thx a lot for your post, it is very interesting to see this complicated piece without his wear :-)

Since 2 months i have also one BC5000 and he needs also new belts. But unfortunately i don't have time for do this now with you...

I've received an original service manual, in French language, brand new. It is fantastically precise!

I have the necessary (nay, compulsory) dynamometres, an oscilloscope and the belts should arrive soon. I will try to find an alternative method to Jari's but I doubt it will be feasible that easily...

Got my deck today. Waiting on belts.

Indeed! It's about the size of a contemporary Beogram!

Good to see it got safely to your place... Let the game begin!

Merry Christmas!

Good!

But first, we need belts...

How about sharing our progress when we both start this common project?

Since Jari is well ahead of us, this thread will be very interesting. This is a real challenge, and I'm sure that Tim Jarman will be glad to help!

Sure, I'm in.
