what an amazing invention!

Just wondering do you need to calibrate every tone wheel or do you just use one to find out the value you need to use and then recap it.

@Denvermorgan2000 No two hammonds will respond the same way to a recap. You can sit and pick different values one at a time while monitoring the scope, but I prefer to replace all at once then graph the results. Then I can see which toneheels really stand out, know if they are too loud or quiet, and adjust accordingly. Who knows, a miracle might occur and it'll be within spec on the first shot! haha

What sort of cost is involved in having this done? (Say with an M-3)? I'm talking parts and labor, about what would somebody expect to pay someone to do this to their organ? My volume seems generally fine except I have lost almost all the sound from the bass pedals. If pull the drawbar all the way out and max the swell then you can hear them, and they sound fine except not loud, and of course at that setting everything else is way too loud. i wonder if having this done would fix that problem

@VeronicaDeVore For the generator: Caps themselves are only about 20-50¢ ea. depending on the working voltage. So just product cost alone, you could have an organ done for roughly $30, give or take for shipping, etc. Labor involved depends on the organ. An M3 should be very easy to work on, and the actual process of replacement only takes a couple hours at most. The rest of the cost depends on who works on it... Add in the drive to and from, I'd say the $150-200 range sounds reasonable.

@VeronicaDeVore Oh by the way, this only really concerns organs with paper/wax caps like in the video. Models with red coloured plastic caps need not be messed with. Your M3 could be either one, the only way to tell is to lift the cover on the generator and look for yourself.
