theres one of these in the buysell for 100$ canadian, just wondering if its one of the tube models, what wattage, and any features i could hack out for guitar use?

That's sacred ground, buddy. It's most definitely a tube model from the early '50s. If it's in good enough shape, you'd be well advised to play it and enjoy. No sense hacking up a perfectly good (and potentially valuable) instrument.

awww but i'm a king of hotrodding, hmm i have fixed up a few reed organs and cheap electric bontempi's and stuff, would it be any good for potential studio use? heh

This ain't no Bontempi. The Hammond B3 is THE KING of organs. Nothing else sounds like one. Hammonds created their unique sound thru a system of mechanical tonewheels. It's a sound so highly sought-after that a well-kept B3 can fetch thousands of dollars. With a Leslie tone cabinet, a B3's price can reach 5 figures. Here (http://theatreorgans.com/grounds/docs/history.html) is some background on the B3.

If you get the M2 (a deal if it's in good shape), bring a few folks to help you carry it. All those tubes and tonewheels in all that wood weighs about 2 or 3 Rockmontons.

930 pounds? eep! i'm a 310 pound powerlifter, andi wont be able to do it alone... heh i'm soooo giving them a call tomorrow!! so how does the m2 compare to the b3?

The M2 is the spinet model Hammond. It is smaller than the B3 and has fewer keys and pedals. It does not weigh as much as the B3...the M2 probably weighs around 200 lbs.
Here is the revision lineup of the M-series:
M: original model
M2: allows switching of vibrato independently on upper or lower keyboards
M3: adds percussion feature

The M-series uses a single Jensen 12" field coil speaker fed by 2 6V6's, power output is around 12-15 watts. There is a radio/phono input jack on it...you could patch a guitar in here if you liked...adding a preamp if necessary. Would not tear it apart for parts!

It uses a motorized tone generator, it uses pickup coils near rotating gears to generate tones. You may have to oil it up to get it going (it requires regular lubrication with special oil).

dang me missed it!

That would have been an okay score...I'd hold out for an M-3 with percussion though. I wouldn't pay more than 2-300 for any spinet, though. They don't have the value of the consoles though they can be good players to bang on. Many areas Hammond cut corners on them. Too much of a pain in the butt to hack for guitar use. The L-100 spinet organ has a good amp to hack for guitar, and has a great tube-driven reverb circuit built in as well. Many players buy an A-100 console (same guts as B-3/C-3/RT-3) and remove the power amp, reverb amp, and speakers to lighten it up. The reverb amp (esp. the early 5-tube unit) and the power amp (2 EL84's) make great guitar projects. The amps often show up on eBay, and sometimes organ technicians have 'em laying around.

TP

I found an M3 last week for $100...the 5U4 had shorted though and the heat melted and cracked the glass! Also there is a burned resistor in the amp. None of these hammonds had fuses which I think is ridiculous...a fuse would probably have prevented all that damage. We have been adding fuses on any repaired hammond consoles or tone cabinet amps. Have not gotten to working on this new M3 yet.

yeah i've gotta find me a nice old tone cab to turn into a guitar amp, i love the way they look! a light wood, some rock and roll handles, and some preamp mods and boom, there you go!

I just cringe when I hear of someone wanting to hack up a Hammond organ. Parting out a battered old organ to repair other organs is a different story.

haha okay, i'm sorry. its prolly a good thing i didnt get it. i'm still looking for an old tone cab to hack up. heh

I know it's an old thread and not pertaining to this exact thing but may
be helpful for others I would assume.

Looking for a schematic for the hammond tone cabinet type G amps. I
have a pair of these mono amps using (4) 6v6's, (2) 6j5, (1) 5u4 which
look to be like they may make a decent pair of mono blocks for home use.

The speaker/ground/B+ hookup I believe I have figured out as it normally
uses field coil speakers and completes the CT to ground through the field
coils. I found a bulletin from hammond on replacing the field coil speakers
with there replacement standard type speakers and they replace the 250
ohm field coil with a 250 ohm 20 watt resistor to complete the ct to ground
connection with using nothing in where the larger field coil was?

The thing that has me a little puzzled is the use of the output trannie coming
back into the output circuit and there is a seperate input wire to each 6j5 to
where I wonder if you just tie the positive input to both those then the neg to
ground, but the schem I have is barely barely legiable plus not knowing how it
would have been done in the organ has me quite confused. Then there is also
a third input type wire it looks like that goes toward the outputs or is feeding
something back to the front input?

So if any of the organ gurus see this maybe they will know what I'm talking about.
No I did not hack these out of organs but got them from a guy who had them in a
garage collecting dust, figured I'd try to put them to use.

Thanks for any and all help if anyone can decipher what the heck I'm talking about. :D

AHH I figured part of it out, there is no phase spliter circuit on these amps.
(Hammond musta been doin somethin funky up front)

I'll need to use a 6j5 for the input tube then say a 6sn7 for phase splitter
and build a new circuit, still not bad as all of the parts on this amp can be
used, just basically a little wiring needs to be done.
