Hello from new member!

Hello all!</P>


My name is Angelo. I'm a guitar player by trade and for the past year I've been getting into keys. I've successfuly collected great boards during this past year, andI have now finally found my Hammond Organ. I just got it today. A M3 and a Leslie 120 for $180!!! If feels like christmas!!! Yeah! This forum was recomended to me by Clavier, who I met at the synthesizers forum. I'm from Brazil and have degrees in Jazz guitar. You can listen to some of my music here:</P>

I'm joining this forum to meet other Hammond entusiasts and learn about the Hammond and Leslie combo. I would like to restore these babies and learn how to do it in the process. </P>


Thanks,</P>

Hello Angelo, </p>

Congrats again on the purchase. I do hope you will make some You Tube videos of the music you make with it. The folks here are friendly and eager to help. There's also a lot of information that already has been covered, so feel free to check out the older threads for inspiration.</p>

</p>

Thanks a lot man!</P>


I'm really happy with it. It looks great too! I can't believe Igot it for 180!!!!</P>


Really cool forum. I've been searching and reading the past threads for the past hour or so. Tomorrow morning I check inside to see if everything is connected. I have to get tubes for the reverb. The leslie sounds awesome. The M3 has a rambling sound after it's on for awhile. It starts quiet, then when it's warmed-up the sound becomes nice and loud, until the rambling starts to get louder. Then the output is low again. I would think this thing needs a recap, no? I'll also check to see if it needs to be oiled. I don't think this M3 hasn't been played in loooong time.</P>


The electro tone presets are great too and it works fine.</P>


I'll surely post some youtube vids with it. </P>


Thanks,</P>

Presets? Reverb? Not on a M3...Are you sure?
</p>

Explain the rambling sound - is it mechanical from the Tone generator, or audio noise from the speakers?
</p>

Re: Climbing and falling volume. Have a look at the output tubes (6V6, El34 etc...I dont know which you'll have because I dont think this is a M3), see if they glow bright red as soon as the organ starts to play loud and then dies down. The tubes have a heater which glows as soon as power is switched on - this is normal. After playing it and volume becomes loud check to see if the tube has a strong dark red glow, or more then usual. </p>

I would add Hammond oil asap. I wouldn't rule out a re-cap, but normally organs of this age do not require it. Of course, it may be responsible for your volume issues. (Just to be clear, if it needs to be re-capped, then it would be the amp capacitors. The Generator caps do not have to be changed). Also, after oiling, the first thing you should do is clean the tube pins and sockets with electronic contact clear. This usually sorts out most of the quirks.

Tudo bem! (I have a cousin in Brasil)
</p>

Try turning off the vibrato switches and see if the noise goes away. If that's it then let us know and we'll look for the solution in the vibrato scanner.</p>

Johnny b3: Yes, the M3's had an aftermarket rotary switch ElectraTone and another brand (Selectone, I think) presets added to the right lower manual where the wood block is. There were different kinds. One had a single switch and the other had a two gang switch that would control each manual separately. Really cool setup but lots of wiring. I have a set of them here uninstalled. I'll try to get a picture posted.&lt;br&gt;&lt;br&gt;</p>

Hi!</P>


Thanks for the replies!</P>


"Presets? Reverb? Not on a M3...Are you sure?" Yes, It's an M3 with the Electrotone presets. And the reverb is there but has no tubes and it's disconected.</P>


"Explain the rambling sound - is it mechanical from the Tone generator, or audio noise from the speakers?"</P>


Audio noise. Sounds like brown noise with some low freq crackling and rambling. With te volume pedal up there's no noise.</P>


Would weak tubes cause the rambling sound? </P>


"Try turning off the vibrato switches and see if the noise goes away."</P>


The noise is still there. All the stops and switches work properly.</P>


I looked inside and it appears to be all connected properly. </P>


Other than noise and low output there's only one more thing.</P>


When I stop thespinning with the switch the Leslie will need help to restart spinning. If I leave it spinning and turn the organ off and then turn the power off the motor starts when repowered. But not if it was stoped by the switch. The small motor is not turning when the leslie is stoped.</P>



</P>


Thanks a lot!</P>


P.S. I figure I'll deal with the reverb unit later.</P>

Re: Hello from new member!



Try removing the tubes and spraying a cleaner into the sockets, then replace them working them in and out some. Also have someone play the organ and wiggle the tubes to try and find the offending one.
</p>

Good chance tubes are the problem.</p>

On the Leslie, it sounds like the slow motor is not engaging the rubber ring on the motor. After years they become flat and won't make contact. You can try turning the ring around so the flat side it to the inside the pulley and it might get some more life out of it. Also there is a screw/nut adjustment on the slow motor. Another possibility is a stuck relay in the switching box.
Clean the contacts.

Re: Hello from new member!

Amazing! were those presets a Euro thing, or do they exist in North America as well?

Re: Hello from new member!



They're all US made as far as I know. Here are two more pictures (just not very good as they were in a box of parts and the flash was too much).</p>

I have removed, cleaned and replaced twice. The noise persists. Should I replace the 6v6s with new ones? Do I need to rebias? Can I place a 12ax7 in place of a 12AU7? </P>


The noise is constant, not only when notes are played. If I remove the 12AU7(output amplifier?)to the right of the 6V6 the noise stops. The output is very low then. When I replaced that 12AU7 with a new 12AX7 the noise was back.</P>


And now, misteriouslythe percussion wont work. </P>


Sorry about the newbiness of the questions, but I know nothing.</P>


Thanks a lot!</P>

Re: Hello from new member!

Don't replace a 12AU7 with a 12AX7. You can't assume what will work in a guitar amp will work with organs. Hammonds are very sensitive to voltage changes, especially the percussion. Keep the tubes stock as they're supposed to be. You can get caps and tubes from Partsexpress.com. They ship quickly. Also Tubesandmore.com

Re: Hello from new member!



If it were me, the first thing I would do is replace all the electrolytic capacitors in the amplifier. While these and the tubes were out of the circuit, I'd check each of the resistors, and replace any that were out of spec. I've heard that some of these old resistors can start becoming intermittent when they warm up and cause such rumbling noises.</p>

Recapping and generally overhauling the amplifier is probably going to be one of my near future projects on my M-111.
