Hi, I have a Hammond B200 with Leslie 415. When turned on the B200 is very soft and takes a few minutes to begin operating at full volume. This is usually preceded by a pop sound. Does anyone have any ideas please and also should I fix this does anyone know how reliable this instrument is likely to be. Thank you Lynne

All. Not a Hammond question. Anyone on this email list in keyboard Repair in general? Looking for parts, system board for a Rhapsody 3 Digital Piano made by Williams, once sold by Guitar Center. Any ideas where to locate one? Thanks in advance. Norm Erwin

I have a bad hum in my reverb only when dialing it from off to on. The more you turn it on the louder it gets. I removed all tubes and checked them and all checked good, then I removed the rca plugs and twisted them to get a good ground , still had the hum. My next step is to remove the spring box and put a meter on it, however I don't know what the reading should be. I always thought a bad ground or open connection should be the problem, I added extra grounding , which did nothing. Any ideas of what to look for would be appreciated. This organ is located in the swimming pool area (inside) and is operating perfectly other then the reverb. Thanks in advance, Di.....

Hello, today I found a torn wick from the oil tub to the run motor front bearing. Well, finally I got it replaced, but I almost broka my fingers during this awkward procedure. I used a dentist's tweezers to wind the new thread around the bushing groove and do the knot. I didn't see by no way how I could have pulled the flywheel from the motor shaft which, of course, would have made the job much more convenient. There's that big thrust bearing ball in the middle of the wheel, but it's stuck, hence I couldn't use a small puller. And there's a small hole from the side, but no set screw within. How can the flywheel be removed from the motor shaft? Best regards!

Hello@all, ...I'm a man of distinctive taste :-). Under another moniker (MenrathU, IIRC) I've been around for a long, long years when Hammondzone was still part of Yahoo groups. And I've been active at the clonewheel board also (btw, where's ths one gone?). Some of my interests are BMW airhead motorcycles, old cars, especially Citroens, electronics, especially tube gear, and I know a thing or two about German Dual turntables that I collect. I'm also active in some American forums that deal with audio electronics and JBL speakers. And, of course, I'm fanatic in music that challenges my brain, e. g. classical, jazz, progressive rock etc. My Hammond passion comminced when I bought a (supposedly) 1961 A-100 and a 147 Leslie (as per it's badge) with 122 amplifier (so actually it was a 122...) twenty years ago. It had the immanent issue with it' wax paper filter capacitors. So I decided to replace them by foil types that I had individually selected for resonance and recalibrated the TWG with the Hammond sound of progressive keyboardists (Keith Emerson, Rick Wakeman...) in mind. Finally, I sold the organ in 2013 to a young musician, keyboardist of www.organ-explosion.de from Munich. According to his wishes I had removed both power amplifiers, all speakers to enlighten the organ a little bit, installed a Trek II reverberation unit and heavily modified the Leslie connector kit that had come with the organ so that he was able to play and control both a 117 Vac 122 and 230 Vac 147 simultaneously. My actual inventory is a TTR-100, a T-200 that is missing it's swell pedal, a T-522 whose generator supposedly never has been oiled (it is horribly loud and the oil pen that had come with the organ was stil sealed) and a beautiful first hand C-2 that I bought last year from a church at Hamburg. I immediatley had fallen in love with this beautiful quatrefoil enclosure when I noticed the ad. It came with two JR-20 tone cabinets that the church had bought together with the C-2, so I assume they were all made in 1951 (but I'm not sure, of course). Last year I also bought the T-200, both the other spinets I hauled some weeks ago. All three spinets were cheap, so who cares? The C-2 is the reason why I returned to hammondzone, 'cause it' got some issues. I'll start one thread or another about these. So long, Uwe

Ive just picked up a C-3 with no speaker. It has a 122 kit installed. Local to me Ive found a 21H that according to the owner is all original and works fine. However he also says its been unplayed in 7 years and he has no way to demo it. Luckily i have a trek II pedal so I can fire it up before I buy it My questions are- Is a 21H a straight plug and play install to a 122 kit or do I need to alter the lit/organ or kit? Are there common issues with a 21H, besides it’s age, that I need to check out? Thanks for any advice!

Hello to all ...and let's hope a happy new year ...although this is yet to be determined. As we are all literally being forced into a different way of life, I, fortunately, have the luxury of having access to musical instruments, one of which is an X77, which I have had for perhaps 20 years, and never really played since I was much younger and played organ almost daily. This X77 has always had problems with contacts, primarily drawbars, hence I was always reluctant to sit down and play for fear of disappointment when adjusting drawbars. Scratching sound, partial loss of notes, full loss of notes ...I think you all know the problem. I just stripped the X77 apart and fully serviced the drawbars ...and they are now better than they have ever been before ...ever. During this 100% disassembly and full cleaning, I noticed three different types of greases (lubrication) used ...inconsistently throughout (contacts, bars, and housing), which leads me to think perhaps some servicing of this organ had been done prior to my ownership. But this is now all cleaned up. Drawbars are 99.99% ( I expect there may be a contact in the 368 that may not function at any one moment in time). Of course, when things get disassembled, changes can occur. I found one change that had be puzzled for about fifteen minutes. Upon full re-assembly, the pedals only, would not feed through the "echo only" channel. The pedals would feed through when both "Main" and "Echo" were operating. I found it was the "dirty contacts problem" in this switching mechanism. This got remedied. Now that the organ was fully operational (sound-wise), I was now able to focus on "sound". The "Main" channel drives the X77 Leslie. The "Echo" channel drives a 147 Leslie. An additional pre-amp is needed to fill the 147's signal requirements. I had always found something lacking from the 147 after I had completed this addition. The pre-amp has gain adjustments for bass and treble and overall output. After this drawbar servicing was just completed, the 147 performance has now in fact improved. It now will shake the room and scream. The pre-amp can be maxed in all three adjustments without any significant detection of sound distortion. However, the power is definitely not needed, so I have backed off all three adjustments to about 85%. So the Leslie 147 is back. I have had this speaker for over 50 years (through my parents). This is what I remember from my youth and playing the A100 and this Leslie ??? Now ...the problem. The sound through the "Main" channel, the X77 Leslie is full of distortion. There never has been distortion before. Even at low volume, the sound is clipping. The volume is fine. Loud is really loud, but all distortion ....and soft is really soft ...but all distortion ....regardless of the channels being used. When I serviced these drawbars, I looked at the first dozen of the contacts on the springs, under a more powerful magnifying glass. They were like snowflakes. No two of the contact surfaces were alike. Each one had varying degrees of scratching, pitting, different surface shapes (none were flat or round/convex), different areas/locations of wear, different shapes/forms of wear pattern, and different oxidized surfaces. Every contact had a fully oxidized contact surface. The only thing I can think of is these drawbar contacts have never ever made proper signal contact ...none of them. One reason why I looked at these contacts closely was due to my viewing of Bob Mann's four videos before I took on this task. Apart from the valuable information on how to disassemble the organ, it was the cleaning part that I needed information and direction on. He points out how "anul" he is, but for an instruction video to be effective, the information should be "anul" to capture all the possibilities. QUESTION 1: is it possible that for all these years, the organ has experience a resistance at these contacts, and now that they are clean, there is too much gain to the Leslie ...from all channels? QUESTION 2: If the above is correct, is there ONE primary adjustment to the Leslie (or
