John, These switches were made expressly for Hammond and so not replaceable with any new, over-the-counter part. You have to service these from underneath. You will have to lift the entire panel that contains the switches, drawbars, and this knob. There should be instructions for that part widely available on the web.

The box containing all the vibrato switches has a removable bottom underneath, and the method of securing this lid did change over the years, going from screws to, later, clips/clamps.? The screws are VERY easy to lose when you get them out, especially when you're trying to put them back in! Advise you get a small screwdriver with a screw-holding clamp. Also, place a towel underneath the screws in case you drop one--
you will. You will invent new ways of swearing.

Once you get in there, you will see a series of gears and linkages attached to the rotary switch. Toothbrush, WD-40, then OIL. Done.

HI!

The vibrato selector switch on my B3 has become hard to turn. The knob stripped and couldn't hold enough to operate the rotary switch anymore. I tried putting some penetrating oil on the switch
but that did'nt work.

Does anyone know the exact rotary switch to buy? Is it just a 6 position rotary switch? I have looked on all the Hammond sites and cant find it available.?

I was also looking for the rotary knob too, couldn't find it either, have to repair the one I have.

Any help would be appreciated!

OK, got that problem solved and ready to move on.
The console hasn't been powered up for several years, so want to bring it up slowly and try and reform the caps.? Do I need to disconnect the -12V terminal and resistor bank plug??
Please advise.

I am in Boise, Idaho and J have a X-66 and matching cabinet. IT is a project but is at least partly working. I need more space and it is time for me to move this out. Anyone interested? Free to an interested person. I am out of space and running out of energy!

thanks

Isn't it the non-drawbar model similar to the Cougar - the Maverick (possibly the 5222 - a model sold outside the US)?
As it states in the description of the Cougar, that model has drawbars and tabs; the Maverick?had all tabs.

I went to the church today, I shocked the 6th harmonic after disconnecting the wire from the drawbar both B and Bb ,?
still had the problem even after beating on the key,, so then I shifted the busbar about 1/2 turn and that seemed to correct the problem. I can only hope it remains problem free.? I would have expected the shocking would have been sufficient.
I left scratching my head...

thanks to all...…? 顿颈...…..

Thanks for the info, I will try this next week. I really cant think of anything else that could cause this to happen. ?
Maybe do both suggestions.? Thanks again...

You would need to unsolder the wire from the end of the drawbar, and connect your batteries between this wire and ground, if you connect the batteries directly to the drawbar, the battery's power will simply be shorted straight to ground through the primary of the matching transformer. I don't know whether or not this would harm the transformer or not, but probably best avoided. In any case the current wouldn't be going to the dendrite, where you want it to go with the wire still attached to the drawbar. Make sure as well, that you have the appropriate preset key selected. It would be no good zapping a drawbar in the Bb group if the B preset was selected.

It does sound like dendrites might be the culprit I think I might try to hook a couple of 9 volt batteries up
pull out the drawbar and try shocking it.? I don't want to damage anything else.? Would this be a solution
without doing any damage to the note or organ?

I got a call from a Church with a problem on an A 100 with a note playing with no keys down, this how it is described to me.
?Lower manual with the 6th harmonic? drawbar pulled out, the 2nd B on the lower manual plays part time without? the note being played, this is on presets Bb and B tabs used, of course one at a time. If you play the first B same manual it stops for a while and then comes back on. If you push the drawbar in it don't play. The organ was moved from one Church to another 2 weeks ago about 20 miles carefully. Original owner said he never noticed any problems like that, but wasn't sure.
My thought maybe a broken wire in the manual, but after looking at the way they are constructed it seems unlikely. Any thoughts on this would be appreciated, something like shifting the busbars, beating on the note, or ???

Thanks for any info..... 顿颈...…..

That's the one. I'd incorrectly described it as the Cougar (a model of the same vintage using similar technology). Got the correct model series number though, 5***. The Cougar series was 7***.

Quite possibly the organ offered by the original poster is a UK (or maybe Europe) only model. I recall Hammond UK doing a big promotion on the Cougar and Maverick as a fortieth anniversary range in 1973.

Sorry to everybody! It seems that all my edits got sent out.I was trying to edit my reply, after adding the photo - trying to add the attribution that Wikipedia requested.

Hi all,

Poking around, I see

(I have no idea how reliable this wiki info is)
it says,
"Cougar
1973–1976
Transistor spinet organ with drawbars, in some extent, corresponded to
a kind of successor of L-100 series tonewheel spinet organ, although
its new drawbars arrangement is slightly exotic; its upper manual has
normal nine drawbars; on the other hand, lower manual has only two 8'
drawbars with sawtooth. This anomalous design was only followed by a
few models (8000 series, 8100 series, and 8200 Aurora series)"
