When you say wiring diagram, do you mean schematic diagram?

I have two PR 40 tone cabinets.? These are both UK 240 volt models and the wiring is slightly different in each. One has stopped working, (only a very feint organ signal can be heard from the cabinet) and as I am not proficient electronically, a friend who is a retired electronics engineer has taken a look at it and compared it to the working model.? The problem is that they are not exactly the same wiring, so he requires a wiring diagram and I have taken copies of the two wiring diagram varients shown on the captain foldback site to give to him. ? I was going to say to him that of course these would be 115 volt USA versions, and in my ignorance I suspect that will be enough for him to work with, but is there a diagram for a UK 240 volt model available anywhere and am I correct in thinking that there are two wiring varients on the PR 40?
Thanks\

Re: X-66 Trouble shooting Help
Video and/or soundfile(s), or it didn't happen! ;-)
But seriously, I've never heard an X-66.? I would love to see and/or hear one.

Re: X-66 Trouble shooting Help
Hey Jim -
Good news is the X-66 is up and working to my satisfaction.? Everything is great with exception of two keys missing the 16' stop.? I added a pre-amp in line with the tone cabinet so I could tweek? base and treble for the 4 channels to my liking.? It really sings great!!!!
?
The good news is? I won't be bothering you for a while.? The bad news is that in the near future I'm gonna start working on my other X-66.? I've learned a lot on this one so hopefully I won't be as needy next time around.
?
Mega thanks to you and others who have offered advise and support along the way.? I owe you one.

Re: Second Drawbar problem?
8' pitch is unison pitch, the same pitch as a piano. 16 is an octave below, 5 1/3 a fifth above, and 4 an octave above. Playing the middle C key with the first four drawbars out, you should hear.? C below middle C, Middle C, G above middle C, and C above middle C. The remaining drawbars should sound, 2 2/3; G in the second octave above middle C,? 2; C two octaves above middle C, 1 3/5; E in the third octave, 1 1/3; G? in the third octave,? and 1; C three octaves above middle C. Highly unlikely that any one drawbar would be playing the wrong pitch, this is determined by the internal wiring of the manual keyboard. Two drawbars could be swapped in pitch if the wires to the back of the drawbars were not in the right order. Correct order is, brown, red, orange,? yellow, green, blue, purple, grey, white,? from 16 foot to 1 foot.
I don¡¯t claim to be an expert but I do believe the 5 1/3 should be an octave plus higher. 16ft- one octave higher 8ft- one octave higher 4ft, etc. ? Rich Reid 208-861-9263 ? ? Hi, Since a few weeks I think something is missing in the upper manual second Drawbar. The sound seems werker.? I just listened to some YouTube videos. First drawbar should be 16'. Second should be 5 1/3'. Does that mean when I press a C I should hear the G above that C? I think I hear that G one octave higher which means a lesser fat tone when I open the first 4 drawbars. Is a wire loose at the back? How ever do I get that wire back in the right place?? Every drawbar works, top and second manual. It's only the second from the top manual that sounds week. (yes I oiled the organ some weeks ago).

Re: Hammond PR 40 Reverb Issues
I realize that you complained only of the sound when using the
Reverb, but caps last only 20-30 years normally, and this should
make your unit sound good for many years to come, unless something
else unusual is wrong. IOW, good preventive maintenance. Pay close
attention to variations in the filter cap design. If you get lost
in that respect, be sure to call Rick Prevallet.

Gentlemen,
I am hoping someone can shed some light on my issues,
the primary one being distortion and some "frying egg"
noise. The distortion is more pronounced on lower notes
especially with multiple notes played together. This
occurs only when reverb is on. All tubes are fine as
tested in another PR 40 and I replaced the RCA cable
from necklace to amp. Two other minor issues, the reverb
is switchable using the chorale/tremolo switch. The
console is outfitted with the Trek II SS1 preamp if I
remember the model correctly, the Trek folks asked me
some questions then said it was a very early model, and
lastly, the bass isn't as strong as on my other PR 40.
Tomorrow, with assistance I will try to confirm both
15"s are working. In summary the unit plays clean with
reverb off but gets ugly when the reverb is on.
Thank You one and all,

Hi,
Since a few weeks I think something is missing in the upper manual second Drawbar. The sound seems werker.? I just listened to some YouTube videos. First drawbar should be 16'. Second should be 5 1/3'. Does that mean when I press a C I should hear the G above that C? I think I hear that G one octave higher which means a lesser fat tone when I open the first 4 drawbars.
Is a wire loose at the back? How ever do I get that wire back in the right place??

Any suggestions?? (yes I oiled the organ some weeks ago).

Re: X-66 Trouble shooting Help
Yeah I've had a few parts knocked off me over the years also.? Shot in 7cc of oil so we're good to go.? Thx.

Re: X-66 Trouble shooting Help
Sounds as though the plastic cup may have got knocked off the top
of the TG at sometime. In the absence of the cup adding oil
through the hole, slowly,? should be fine.
