My Dad was having a new refrigerator delivered. There is a nice Mexican family across the street fixing up a powder-blue 63 VW Beetle. Another Guy across the street was installing a new front door and getting rid of a funky old 1970's fridge...It was a busy day on the East Side!
TCS was waiting by the time I got over to my Dad's house. He was going to rewire a few of these connections first. We noticed a definite grounding hum, and tried to isolate it.
TCS mounted a vice clamp onto the organ (the white paper to protect the finish), this provided him with a steady hold for the delicate soldering job on the connections...Ahhh Lead fumes, why do I like that smell?
The encouraging news was all of that oiling last week paid off...The M3 started right up, and there was no squeal from the tone generator...Yeah! So far I'm in for $10 for a new supply of Hammond oil.
Actually, the "wicking" mechanics on this machine are genius...There is a hair-thin wire above that drips oil from that copper resevoir and oils that motor...This was the squeal source...Also that metal pin jutting out there no longer needed to be poked into place in order for the starter to engage, It did it all by itself!
The crap news of the week? The "Field-Coil" Speaker need to be completely reconed, or replaced. The tear was just too significant.This would be my next task- Finding the replacement (TCS says it shouldn't be more than $25...I hope!)...that and replace some...TUBES!
Well that Vibrato problem was isolated...It seems to be one of the tubes not working. We figured this out by swapping the two 6AU6...TCS also didn't like that the Rectifier tube (5U4GB) Arced when he tested it in his guitar amp, so that needs to be replaced too...Plus there is a missing pre amp tube 6C4, and what about two matched 6V6GT's...How much for each seperate versus a "new" old set? There was a whole set on ebuy for about $90.Either way...It's a small price to pay for a Hammond!
Whenever the Vibrato was "on" we got almost no sound...We swapped the two Vibrato tubes (one is good, one obviously is dead), then we got Vibrato...Though it would die when we turned the Vibrato "off"...SO: Next Week...
1)Field Coil Speaker repair
2)new tubes
3)Start thinking about legs, and transport design
4)Haul all of my tools to my Dad's garage in order to build TCS's rotating speakers.(I'll post this too as a seperate project!)
Well off to Puget Sound Organ to see what they got for Speakers and Tubes!
