Bass Pedals do sound, one is stuck. That looks relatively easy to work on. Good to know both amps working. Some drawbars not functioning ( on both the t212 and the R195). Just discovered the top access for the tabs and drawbars, very nice

Re: Good news and bad news
Great Scott. Yes I do have a multimeter. I can send pictures. Do you want to keep the training of me as technician through the hammond email? Or just do it over WhatsApp. That goes faster. I am telephone : 0033768713011 ? Blessings Ali
Wow!? Never been to Europe!? I guess that's where all the old
stuff is, right?
OK, so you have to become your own technician then.? Do you have
a meter of any kind? If so, perhaps we can lead you through some
of the steps below.? I don't know how to say "meter" in French.
(Or anything else.)

More bad news: there are many
reasons that 122 switching can fail, and you need a technician
to look at the situation.? Without wishing to offend, your
description of what you did to "the relay wheel" and "the
transformer" has no basis in reality. These are terms that
simply don't apply to this situation.
A technician would look at:
-the "switching kit" in the organ, and the DC voltage it is
meant to produce (between 30 and 120VDC to ground)
-The B+ voltage that drives it which can come from the organ
OR the Leslie, depending on the particular installation
-the 12AU7 switching tube in the 122
-the 1 Megohm resistor that drives the tube
-the two blocking caps on the signal input
-operating voltage within the 122
-damaged/non-working relay

The amplifier is basically a stereo (2 channel) version of the
amp in your T-200. Usually quite reliable. Tab switches on
transistor Hammonds of this vintage can cause problems, perhaps
the tabs aren't switching the sound back to the main channel when
up? Do the bass pedals sound? They also use the main amplifier and
speaker.
R-195 solid state. only the leslie?amp is working so the only
sound I am getting is from the spinning 6x9. Does anybody have
experience with this model?

Re: Hammond Tech in Denver?
Just an update. I eventually got to my previous Hammond Tech, Mike Ditto. He's now "Music Gear MD". Hauled the A100 up to him. He restored EVERYTHING!
Recapped & recalibrated generator, cleaned switches, cleaned busbar, cleaned drawbars, replaced out-of-tolerance parts in all amplifiers, rebuilt chorus/vibrato, fixed preset switches, changed out felts, added a stop position to my speed half-moon... Even calibrated the output to my Leslie. The Old Girl now sound like new AND I will never have to move her again (I told my daughter that would be her problem when I was dead!).
Fantastic service. Really happy.
Cheers! Paul

TP Folks,
My A-100 has become essentially unplayable due to generator bleed and crosstalk. She is long overdue for a recap. Main output has ceased also (Leslie hookup still works) and bottom preset keys won't hold.
The local repair place I had planned to take her to has lost their Hammond Tech with no replacement in sight.
Can anyone suggest a Hammond Tech in Denver Metro? This is really too lovely an organ to trust to me doing the work.
Any suggestions would be appreciated.

Re: Foam on the last production 3-series consoles
I have a 1972 B-3 and I've never incurred any of these heretofore mentioned foam problems. Some production values may have been altered in these later models, but I don't know that for sure.?
Sadly, these organs were discontinued in 1974.

I recall reading somewhere that the last production Hammonds used a different type of foam that didn¡¯t have the issues of the previous years. Can anyone confirm this?

Sometimes the is a cold solder junction at the point under the upper manual, where the bundle of resistor wires is soldered to the terminal. You may resolder this spot.
Regarding the muted vibrato: R20 (2.2 M) in the AO-28 vibrato channel often is the culprit. When you are at it also exchange R7 (2.2M in the normal channel).
Can be zinc whiskers in the vibrato rocker switches as well.

Much is involved in opening the manual to fix the fault on 16' A3
note. Very likely, this is a foam related problem and the resistor
wire to this contact will have been corroded away by the acid
produced by the decomposing foam. Other resistor wires in both
manuals are likely to be also affected, although not yet corroded
through.
Low volume when switching vibrato on/off is likely to be related
to the circuitry around one of the 6AU6 valves on the pre-amp. One
of these valves is the first stage pre-amp for the vibrato
channel, the other the non-vibrato channel. Open circuit, or at
least much higher than nominal value anode and screen grid
resistors are a common cause of low volume on one or the other (or
both!) of these pre-amp channels.
