Ah ha!!

So let me get this straight - my "head block not isolated from rest of
frame" question and my "ever seen a microphonic Mellotron" question have
inadvertantly collided with each other! This happens to me quite often, I'll
run up to somebody and start yapping and then say "Oh!" and "Thanks!" and
then run away without that person ever uttering a word.

So what does Steve think about your drummer jokes? Hey wait, I have a link
to musician jokes...

(there must be a list of Mellotron jokes somewhere...)

Best Regards,

ah, "percussion maintenance". aka "borrowing the drummer's screwdriver".
the
heads are supposed to be earthed (grounded) to the pre-amp and not to any
part of the frame; this is because there're 35 of them and a shit-load of
gain required for succesful operation. each note adds another 3dB, more or
less... so any earth currents running around the chassis would be amplified.

there's something martin or someone else will add about dc coupling and
gaussing up the heads, which I forget at the moment. I had a corroded
belling-lee connector going into my pre-amp box (ouch) which I replaced with

a hard-cable before i knew about this issue, and never had any problems.
while the corroded connector and old cable was there, I'd get interesting
crackles (as on "rosemary's baby" on our first album) and occasional
microphony. JB or martin replaced my cable with a new belling-lee but I
think
they left my extra-thick earth cable in- maybe the pre-amp is decoupled now,

I'll have to look.
