Can you post some close-up pics of the actual laser unit and its flexible PCB.

You may have to do some disassembly here.

I'll try and identify the replacement laser for you.

Hi Menahem, here are some pics from the unit (I disasembled the PCB)

Tomorrow, I'll go through my laser database, but in the meantime, you should check the ESR of all those SMD electrolytic capacitors. Perhaps the laser is fine, but it is not getting good power because of bad capacitor(s).

Do NOT touch that variable potentiometer between the capacitors - it has nothing to do with laser power!!!!!

Hi Yachadm.  Did you find someting?  I saw on ebay a VAM1255 laser for sale. I searched on the internet for the difrence between a VAU en a VAM. I didnt find the answer.  Do you know where i can buy the sprockets, i want to replace these as well becuase they look a bit worn

Hi Paul

I didn't forget you. I contacted my supplier in Taiwan for clarifiaction, but as yet, I have not received an answer.

I'll send you a PM if I get something.

Anyone want to hazzard a guess as to why this servo motor was a tiny bit strained when running one way bit when rotating the other was fine?

What is that????

Wonderful photo!

Do I see part of the insulating(?) wrap around the winding flapping about?

Well spotted Mika!

@Menahem this is a naked servo motor out of a 400x series...

Yes, a swiss motor of remarkable quality that equips 4002/4 decks. I restored mine some time ago.

Away from home working on a 40 long tons printing m/c, want to go home a start on my BM 4000, parts from Martin arrived.

Best of luck.  Love my BM4000.

Hi did you find out? I need a vau1255/21 for my beosound 1, it's the same as the one pictured. Been following your updates for an answer!

Sorry, no answer on that one - maybe it's an unnecessary question, but did you try your local B&O dealer?

My local dealer won't sell me parts! 

Finally got to it, here

Hi and a Happy New Year!

As it is my first post in this forum I'd like to share my good mood because of finishing my work on my "found in the rubbish for free" Beocenter 1800.

Turntable motor wasn't running, some small but easy to find broken wireing issues and finally a not working speed selector.

But as of this afternoon everything is fixed and tested. And after a friend of mine told me his parents wanted to get rid of their Penta 3s - it even sounds more than wonderful!

On the first step I thought everything should stay original, but I couldn't help pimping the wiring a bit: Additional to the DIN jack it now has stereo Chinch jacks IN and OUT - even they are working perfect.

Maybe for the next step I'll try to revive my Sony D-99 Discman ;-)

Good job Sidi, and a good looking Beocenter, if someone else contacts you about "getting rid of their Pentas", please contact me, I can help 

My 3rd pair Penta's refurbished with new cloths and a selfmade perspex cover and stainless steel mirror panels (yes, again) for the amps.

For this I had to make something. Why not using a halogen lamp from a copy machine to do the bending of the perspex.

ingenious Leslie. Beats a heat gun

Hi Eugen, long time

Good job Leslie, I use to heat an iron tube, shaft or flat iron, depending on the bend type, but your idea is exelent, must check in the shack, there must be an old copier somewhere.

When you found your copier show us what the result is Soren

Leslie,

"The Cx50's & 100's & now your own creative use of a halogen lamp for The bending of a selfmade perspex for those formiddable looking  blk & red Pentas!*Haay, 'You The Man"

Keep On Doin' your Thang!

You Do it wel!! My Friendl...One of these days soon I hope too learn even if I have too cross the pond & come knocking at your door'
