New (to me) A-100: Noise from edge of TG

[Guest]

</p>

Hey guys,</p>

 So I posted a few weeks ago about my new A-100. It's in fantastic shape and plays wonderfully especially since I fixed the percussion and re-felted the upper and lower manuals (what a difference!). I have oiled it several times in the past few weeks including trying the "hair dryer trick" and it is much quieter. However, I am getting some noise out of an area that I can't figure out how to fix. I have a picture below coorasponing to my questions.</p>

Item A: This is where the bulk of my noise is. It sounds like it's running rough. Is there anything I can do to fix this?</p>

Item B &amp; C:<span class="Apple-tab-span" style="white-space:pre"> </span>What is item "B"? It looks like oil wants to go in there (but I didn't, don't worry). The strings coming out of item "B", labeled "C". Again, what are these/what are they for? Are they wicks? </p>

Thanks guys for helping me out. I plan on using this organ for recording so I'm really trying to get any mechanical noise and hum to disappaer.</p>

 Thanks again!</p>

Hi</P>


A is your vibrato scanner and B is an oiling cup. On my Hammond RT3 there is a small metal pipe feeding it from a resevoir higher up in the organ. When I oiled the organ for the first time at the top, the oil was fed to the two generator cups from one resevoir and to that motor cup by the other. C is the wick feeding oil to the shaft. There was still some oil in the motor resevoir last time I looked a week later.</P>


One last thing haveyou checked all four corner springs are in place? The back one behind the scanner was off in mine so all the vibration from that end was transmitted through the console.</P>

B is an oiling cup. You need to put oil in it. The little strings carry the oil to the bearings via capillary action, yes, oil does indeed run up hill! When all is working good you should be able to see little drops of oil hanging off the string like little snot drops hanging off your nose on a cold day.</p>

If you carefully kept any oil out of the oil bath, I would suspect that is the cause of your noise. I would lightly spray it all with WD40 (just a bit), it will take the hammond oil a week or so to crawl around where it needs to go. </p>

Item C is your vibrato scanner. It is actually a rotating electrical condenser. If your organ ever starts 'motorboating' , making sounds through the speaker that sound like an outboard motor idling, it is because your scanner has grown little dendrite crystals inside it,- another topic. </p>

Noise that is coming from that area (not from the speakers) would likely be created by dry bearings or loose parts flapping around.

Thanks for the clarification guys! I out oil in the cup and we'll see what happens! Also, all my springs are in place so that's good. </p>

Thanks again!</p>
