Hammond H112
« on: October 14, 2011, 04:12:05 pm »
I can get one for $200...Original tubes and speakers....2-GZ34's GB 4-12 ax7 7199's 12au7's 2 6v6's I think and 4 el84's ...all branded Hammond but all may be Mullards?
Big Iron and 15" alnico speaker 2 8's or 10's alnico....It's in great shape (no power cord) it was cut of but the short tail that was left was very brittle and falling apart so it may be fine.....I'd hate to part it out but I would ....I'd like the 15 and the GZ34's for my Vibroverb ....My question can I still turn a profit on the parts ....should I repair it and find it a home? What do you guys think?? :BangHead:

Personally I think $200 is high if you are going to part it out. good price if you want to play them.

Hammond organ parts and such still command a fair price, but you may end up waiting for the right buyer.

I harvest a lot of organs and do pretty well. But I don't buy every one that comes my way and I seldom pay more than $30 or so for them. (Hammonds usually cost more, but my A-100 was free)

You have to ask yourself what those parts are worth to you (speaker, tubes) and how much you'd need to get to break even, can you wait that long to get your money back, hate ebay?

Tubes: unless it's an AX7, or 6V6, 6L6 etc you'll never sell them. You might want to test them first.

There should be a Reverb pan in there, can fetch about $30-50 depending

Iron gets about $30-50 for all Organ PT's not very desirable. 6V windings are so big they are inpractical, The ot will be the prize. Should be a reverb tran too, but you can get em new for $20.

I cannot remember if Hammond used bumble bee's, but if you find a few red red yellows the LP guys snap those up quick at $40-50 each!

You'll also get bunches of wires, and many many slotted #6 screws

From what I can tell ...they is some valuable stuff in there , but just moving it would be rough....I'll most likely pass as it would take forever to sell......Maybe I'll fix it for them for a fee...lol sure would like the tubes and speakers though ............

H112 has some desirability to Hammond Players.  It's a tonewheel model which is what Blues, Jazz, Rock organists like.  The H112 (along with it's X77 brother) are the most complex of the Tonewheel models. They can be temperamental but are still a pretty good unit.
Hammond used good stuff in their Organs (Tubes are usually RCA and Mullard and some Sylvania), but I hate to see them get cut up..... to me it would be like sawing the neck off of a Les Paul just for the tuning pegs.

The real question is who made the 15" alnico speaker... Some of those are quite highly prized.

In the era of an H112 it's 99% likely it's a Heppner if it's original.    They rotated from Jensen to Rola in the 1950's back and forth...then Rola to Heppner in the early 60's.... after 1965 nearly all Hammonds with integrated speakers used Heppner.

Definately not Jensens ...But they are high quality for sure....I'd like to see it go to a place where it could be enjoyed for the next few decades....BUT if it is going to be parted ,I can do that as well as the next person...The gz34's are Great Britain as are the EL84's I'm not sure about the 12ax7a's,7199's or the rest It's got the bass pedals too, I don't have the room,but I could take it to a friends and strip it out....It really would be a shame, but, I'm not sure what if anything is wrong with it other than the cord being cut off....The insides look good, but that means nothing.....

High quality was important... That Organ cost around the same as a brand new Buick in the year it came out.

The H112 sold for between $3500-3700 in 1965.

Well it was still there so I snagged it at a good price...it's an early H-model so it's got a handfull of 12ax7a most tubes are great britain
Channel A Amplifier: 7199 and 6BQ5 (2)

Channel B Amplifier: 7199 and 6BQ5 (2)

Bass Amplifier: 7199, 7591(2) and 12AU7

Reverb Driver and Preamplifier: 12AU7, EF86, 7247

Power Supply (AO-71/AO-71-1): 5AR4/GZ34 (2)

Percussion Gate Amp: 12AX7(2) and 12AU7 (1)

Pedal Sustain Amp: 12AX7 (2) and 12AU7 (1)

it's got a 25 key bass pedal, nice alnico speakers.... ....there is a nice amp or two in there somewhere.....and needed parts for other owners

I will audition the 15" alnico in my thunderbolt and if it's sounds better than the Jensen...I may build a thunderbolt....

So are you parting it out?

 :dontknow:  The power cord was cut off before i purchased it ...what's left of it is hard and brittle about 3" long, my thoughts are to put a new cord on and see what happens. I read that it has 67 electolytics, I honestly can't put any dough into it and I overextended myself a bit on the purchase so unless it's an easy fix or someone wants it as is ...than most likely it will be parted out...I'll be less vague by next weekend....has something piqued your interest?

when I picked it up, a conn had come in it has 80 tubes in it mostly 12au7's a couple 12v6gt's 4 or so 12ax7a's etc. pretty cool and it works......

Why I asked is that I am looking for a specific part for a Hammond that I have, but I'll have to go over the rather complex H100 schematic to see if it has compatible components.

Mines an early version H-100 the 12 designates walnut hence H -112
http://www.myplanet.net/x77dude/h100.html
I'm pretty sure that the later version h's did not have the small ( up-top) chassis with the cap can and six 12au7's facing out   it had more transistors??

 So today I decided to just splice a 2 prong cord on the stubby end of cord that was left protruding, the insulation outer and the two individual wires crumpled to nothing...real crap I've seen cords from the 20's hold up better...I just took a crap shoot that inside the chassis was not shorted together....it functions well....sounds pretty good....little bit of noise comes and goes ...I'll clean the sockets and see if that helps...maybe a plate resistor or tube....but all and all It's a working Hammond ...nice tube reverb and nice tube tremolo...... :worthy1: Drawbars are really cool with the foot pedal   :worthy1:
I wish I could keep it ..."NO ROOM"

That 1960's cord is awful.... it's made from a type of plastic that didn't last long. (Rumor has it that it's clay based, but I don't think so) It's about the only part of these that didn't last.
I've owned 4 Hammonds from the 1960's and have had to replace every cord..  I have a Hammond from 1935 and the original cloth cord is pristine.

Yeah the "12" cabinet is a very common one. "Traditional Style"  The overwhelming majority of all Hammonds are of Walnut veneer finish, followed by Cherry.  Oak and Mahogany were offered but are seldom seen. The ugliest of them was the "02" but I don't think the H100 series had the "02" but others did notably the A100.

H100/X77 was the most flexibe in tonality with the pedal clavier. A lot of circuitry went into this, and many H100s had some reliability issues when compared to the venerable and simpler (relatively) B3..... so the H100 gets an undeserved bad rap...

When I asked if you were parting it, I had the idea in my head that it would have the transformer for the external tone cabinet output as many consoles do. (6 pin Amphenol socket) I looked over the schematic and it appears to be tube coupled rather than by transformer (a la B,C Hammond consoles.) I'm trying to locate one to send a balanced signal to one of my Leslie speakers.

In this case probably not. The impedance of signal sent to Hammond/Leslie tone cabinets is ~15-16 Ohm.

I pulled out the power supply chassis and replaced the cord ,cleaned all the sockets, oiled the motor and put it back together....Looks like new caps under hts PS and one can on the power amp is newer looking and different brand.so it's had maintenance....I haven't and most likely won't remove that chassis....
I put it through some paces and it seem to be quiet.......I have not tried the 25 key bass pedal because I used my MC table to take it off the trailer....that was fun by myself but it worked.. I am confident the pedals will work as they should though....Now to find it a new home........
