A100 Pedal Draw bar tone stuck
|
I had this problem often on my old Hammond. The kids in church stand on the pedals... And the some of the small boards making contact broke. Unscrew the pedal, cut from plastic the same size as the boards and the problem is fixed. I first tried to glue the boards back together with some plastic strips but that would not hold long. Plastic replacement works great for the next 50 years...?

But how do you know none of them are stuck and still you hear a sound (of one pedal?) What sound do you hear? Which note is it??

E.g., each one produces a tone as long as its pressed so none are 'stuck'.? Im pretty sure its the tone generator.? Something to do with the contacts? |
¿ªÔÆÌåÓýHi!Not sure if this helps but I remember a similar problem with my A100 which Chris fixed for me. If one of the metal contacts at the end of on of the pedals is slightly bent out of shape, it can be making constant contact and will therefore sound that particular note on both 16¡¯ and 8¡¯ pedal drawbars. Chris corrected the contacts that were out of shape and just as importantly he replaced all the felt for the pedals. Works like a dream! Seems that you need to determine whether the sound is a real ¡¯note¡¯ or not (not sure if this was mentioned in a previous thread so forgive me if I am repeating it). I¡¯m not very technical - the expert is Chris!

¿ªÔÆÌåÓýProbability is that a pedal note is sounding perhaps only some
harmonics, not the full tone. I would remove the pedal board from
the organ as my first step. Just lift the "toe" end of the board
and slide it out backwards. Chances are, the stuck note will stop
sounding. Often a pedal board not correctly aligned or tilted by
an uneven floor will have the effect of slightly depressing one of
the contact plungers. If pulling the pedal board out stops the
stuck note sounding. First check that all the steel springs on the
end of the pedals that push the plungers down are level. If one is
slightly bent downwards, this may have the same effect as pressing
the pedal down slightly. After checking the springs, refit the
pedal board with the organ switched on and pedal drawbars pulled
out. You may find that you have to juggle the pedal board around a
bit to get it to sit right on the frame. More often than not, you will find that the stuck note disappears
when the pedal board is removed. If it doesn't, then there must be
a problem with the key contact assembly. Under the black felt on
top of the pedal contact box, there are a series of plungers, one
for each pedal that operate the pedal contacts. Pressing one of
these should cause the relevant pedal note to sound (at least one
pedal drawbar out of course), and the plunger should spring up
promptly when released. If one of these is sticking down, then at
least some of the harmonics of that pedal note may sound without a
pedal being pressed. It's quite rare for the problem to be in the
contact box though. I can't recall one instance of this happening
in nearly 50 years of servicing Hammond organs. On 18/04/2022 18:47, john
