Bigsbybender's Latest Score!
« on: November 08, 2010, 09:32:26 pm »
Hey all...

I thought some of you might be interested in my latest score. It's not "tube guitar amp" but is tube and sounds just as good!

It's a 1936 Hammond Model A.  The 810th Hammond organ ever built, made about the 7th month that these were in production. I got it for $100 on Craigslist. It was sold as is because the internal preamp is not self powered, thus it could not stand alone through a guitar amp. Hammond used a multi-pin connection that fed the preamp from the Tone Cabinet (Separate Amplifier).  I rigged up a temporary power supply and ran it through my 5F6/JTM45 amp that I built, it sounds incredible!

Check out the Tubes!  A 56' Triode and a 57' Pentode!  It's hard to believe that it's 1936 as clean as it is!

Below I have the tone cabinet amp as well.... I wish I had the original cabinet. It's rated for 20w  and uses a quad of 2A3, 5Z4 recto, and a pair of 56' triodes!   The power transformer is pretty toasty looking so I haven't fired it up yet... It also doesn't have a plug for the wall, instead it gets 115vAC from the Hammond Organ Console via the multipin cable.

I need a cheap compact power supply to provide 200v B+ (There is a separate 2.5v filament transformer). I was directed to this http://www.mouser.com/Search/ProductDetail.aspx?R=IHB200-0.12virtualkey59720000virtualkey597-B200-0.12

I was tempted to flip this for more money..... but now I may keep it.

I played & gigged with a keyboard player in numerous bands between 1975-1980 who had a Hammond A. I am sure I heard him explain that it was a great piece several times over but I can't recall the details. I know it had the same (or similar) type of percussion that a B-3 has. I must have been a lot stronger in those days because I moved that beast more times than I care to remember. And yes, it had 2-digit tubes. I can't recalll if the amp in his Leslie was unusual...meaning, whether it used 6550's or not. It was unquestionably a great sounding organ.

There are sure a lot of those old Hammond organs being gutted on ebay, etc; for their amplifiers. I can certainly understand, they are big and heavy and expensive to maintain on those rare occasions when they need mtce. if I were offered one even for free I couldn't take it. But I am sorry to see these scrapped.

Hammonds have such a sound all their own, I've got my kids trained pretty well and can tell a Hammond or a Rhodes electric piano when they hear them.

Earlier this spring my 14 yr old daughter started sputtering while we we're at 5th 3rd field watching the Mudhens. "Daddy! they're playing a B3!"

A father couldn't have been prouder!

I've never seen such an old model Hammond, you have quite the relic!

I hope you enjoy it for many MANY yrs.

When you get the pedals and the bench with it, and the cabinet is in decent condition, it becomes harder and harder to justify stripping it down into just a chassis and some trannies. I hope you or one of yours plays kbds and equally importantly, you a have a place to put it!

Nice score.   :smiley:

I just picked up a very clean "A" just like yours last night. 
The organ deal included 2 of those nice 2A3 triode power tube amps and 4 field-coil Jensen A-12 speakers. 
All items in quite nice condition for pre-war FDR era stuff...

Nice job BB!  I saw an old Hammond catalog from the '30's that had a pic of a 4x12 cabinet for church/auditorium that was a dead ringer for a Marshall straight front....

I bet if you did a nation-wide search on CL you could rustle a powered cabinet up!  Good luck!

HMMMMMM maybe they had that idea before Jon Lord..... Perhaps Highway Star was actually a depression era song... :wink:
   
I need to hook up a Leslie to this, but there will always be a Marshall hooked to it as well, for obvious reasons. A JTM45 is on it now, the 18w Stout may come soon

If I can snag the original style tone cabinet, then I'll restore the whole thing and sell it to a collector or somewhere that can properly display it.

These things are the pinnacle of craftsmanship as far as electric musical instruments go. I also began the chop of my 1965 Hammond E182 tonight.  Since the cabinet was in rough shape, it makes a good candidate. I removed so much bell and whistle circuitry that I think I have hook-up wire for the rest of my life.  IT sounds better the more I strip it to it's basics.

AWESOME!  That would be the A40 cabinet....  Great Score!

Yeah for Hammond restorations.  They're fun to work on.  I cleaned up a little spinet I got for $50.00 and gave it to my daughter's boyfriend.  He still needs to get that thang outta my house.  There's a really great Hammond website that tells you how to fix just about everything.  It has a clickable tone generator chart for tracking down those pesky broken wires.  It saved me hours of searching for needles in the haystack.
