M3 tuning

[john espy]

I just acquired a 1959 M3 that sat ofr many years. All of the key work except the upper and lower middle "F" is sharper and lower in volume than the rest of the keys. Can Hammonds be tuned, or how should I approach having this repaired. I look forward to hearing from everyone.

Best, John Espy

i am not an organ tech nor do i pretend to be one, but i have been told you dont tune the M3. it is a matter of tone wheel tunning too fast or too slowly at that particuler spot for the middle"f" key.

my father's M3 had a similer problem but his upper C notes where to slow (out of tune). i oiled the heck out of it (it had been setting for many, may years and it was bone dry) and it works great now.
back to your's: it may just be a matter of oiling it. since you say it sat for many years this "could be" the only thing you will need to do. ONLY USE hammond oil for in it.

i hope i have been of some kind of help and hopefully iif i am wrong on this one of the techs on here can help you out.
good luck and sorry i was so long winded

Thanks so much for your help, I actually did oil the heck out of it and it was in fact bone dry and it did help some thats for sure, but it still is 'off' so hopefully oneo f the techs may have an idea about adjusting the tone wheel. Once again thanks so much for your help.

Best,

John
