Re: Leslie 330 - theoretical question
Thank you Chris and Christoph for your responses.? It sounds like it's probably worth taking a chance and plugging the 330 into the B3000 again.
As a matter of interest I think we can rule out any issue with the 28 VDC.? That was actually my first thought as well, but then I realized I had used an 11-pin cable with only 9 conductors, i.e. in a pinch one day I had converted a 9-conductor cable for use in 11-pin systems by changing out the terminal hardware, but just omitting the connections for pins 9 and 11.
Looking at the schematic I think I can understand why a faulty C1 would cause the "no motors" symptom without blowing a fuse.? But I don't see the connection in terms of how it could cause the "no audio" state, since the amplifier is powered through T1 and not T2 - ?
In any case I'll take the plunge and try the B3000-to-330 hookup again; will report back.? Thanks again.

Re: Leslie 330 - theoretical question
The only thing that comes to mind us the fact that B+ (28V) is supplied from the Leslie to pin 11 and goes to the Organ. The organ in turn connects pins 5 and 6.
I don‘t have the circuit diagram of the 330 at hand right now, so I cannot say whether T2 or C1 are involved in the 28V generation circuitry.
OTOH I‘d judge the risc of damage by connecting the B3000 as low.

So my question: assuming everything on the organ is stock, is there any way the B3000 connection could have caused C1 to give up the ghost?? Or was that fault most likely a coincidence?
Am I asking for trouble if I try the Leslie on the B3000 again?
Thanks in advance for any guidance.

Re: Leslie 330 - theoretical question
I've just had a look at the schematic, I can't see any way that a fault in the connected organ could cause C1 to go short circuit. From experience, failure of such power supply capacitors is rare, but when the do fail, they go short circuit. I've known FZ1
in 240 volt 11 pin Leslies to go open, causing much the same no power symptoms.

Hi?Matthias
M series motors are different from the L and T
series motors unfortunately. I think an H or E might work
depending on rpm - basically one from a tonewheel organ with a
single on/off switch as opposed to separate start/run switches.
All the best
Stevie

Thanks to all. I already arranged it with Christoph, since he first messaged me and lives near to me. This is a world wide group!

Hi Marin,
I should have an M-3 start motor in my storage here close to Vienna. If you want me to I could go there and take a look if it is still there.
Best regards, Matthias

Hi Marin,
the L-100 tone generator is powered by a self starting synchronous motor, isn't it? Hence, I'd expect that a motor of any other self starting organ would fit, even that of a T series organ. Have some search at perhaps you will find one.
Best regards!

I have a Leslie 720 and an 822.
When I hook up my 720 to my B200 and choose the rotor from the lilac leslie buttons, some sound still comes from the small main speakers. Has anyone any ideas why that is happening please? Also the ensemble button is not depressed. Thank you.

Yes, a T-series motor will fit. Motors for organs without belt driven vibrato scanners (L, E, R, and early T-series organs) have a shorter shaft, only extending from the end of the motor nearest the generator. Motors for later T-series with the belt driven
vibrato scanner have the motor shaft extended at the both ends to carry the scanner drive pulley. The latter type of motor will fit in any type of self starting organ, but only motors with the shaft extended from both ends will work in organs with a belt driven
vibrato scanner.

Would you possibly like to sell it? How much would it be with porto to Cologne, Germany?

I thought it was, a friend replaced it, but after couple weeks the motor completely stopped working. Then I brought it to a serviceman and he told me that motor is dead

Are you sure it‘s not just the capacitor?

Thank you very much, Chris.? I'll admit I had gotten confused because I remembered a 5-to-6 pin connection between a C-3 and PR-40, from years ago.? I had forgotten the 5-pin end was done that way precisely because the -3 series preamps no longer required
the B+ voltage.? So I had originally been thinking the 5-pin pigtail output on this BCV was "Main," and the 6-pin was "Echo" - when of course it was precisely the other way round.
So then I did some continuity testing on the A/C wiring (with the organ unplugged, of course, as advised!)? But there didn't seem to be any problem with the mains connection on the 6-pin ("Main") output.? So I was puzzled again... until I remembered the advice
I had read on this very forum, years ago: *don't forget to check the cable*.? (Was that from "Organ Freak"?? Whoever it was, that advice has pulled my chestnuts out of the fire more than once!)
Long story short, swapped in a new cable and... glorious sound!? Incredibly, everything still works on this old girl, after it had sat for decades in a filthy storage room.? I particularly like the chorus generator - a similar sound to the scanner vibrato/chorus,
but more complex and pleasant to my ear.
Anyway thanks again, the wealth of knowledge and advice on here is very much appreciated.

I found a company near me in West Wales that would rewind them for me. Not cheap at ?200 at time, but the chapels that owned the organs were happy not having to buy a new organ. I think I've still got one of the rewound motors in the house. I've also got some
modern versions of the run capacitor to go with it.
