Senior moment!

And a neat organ too, Steven. I got to rambling ant forgot what I was posting! Beautiful walnut cabinet and the burl on the front of the speaker! With all the hand wiring on this one, can you imagine what it would cost to build it today?
 
VERY nice instrument-Remember a church we went to when I was a child had one.These Hammonds are popular with the major label recording studios-they have one or two in the stock of intreuments for muscians to play during a recording session-they don't have to slepp their own-but some do anyway.In the Muscians Friend catalogs you see synthesizer instruments to try to duplicate the Hammond-not so--you need the REAL THING!!On the tube amps-agree intently-they handle overloads better than SS models-and less likely to BLOW-OUT!!The "Bottles" can take more abuse!! same as with the transmitters!!I regret I can't use MY McIntosh MC-60 power amps with my home theater system because their caps are blown-can't find any for them.I would like to use them again.I could use my present Receiver as a "processor" to drive them(it has line level outs) that could drive them.Theaters used to use them or similar amps to drive the highly effecient "Voice Of the Theater" speaker systems for the glorious sound-esp with MAGNETIC soundtracks instead of todays digital ones.Real theater fans loved the Magnetic soundtracks.70MM film presentations used them in the days before digital.
 
cybrvanr thanks

Thank you for posting your pics. I had no idea, how an organ worked. Something different and i truly learned something.
 
Tried calling the McIntosh factory near Bingham NY a few years ago-they explainedd they don't carry the capacitors for the units. The Mc tech explained that Cornell dublier made the caps-they were a special type made just for McIntosh for that application.I was still looking for awhile than gave up because to make up caps (they are multi-section ones) would be VERY expensive.Was looking into the feasibility of replacing the electrolytics with oil filled caps-would last even longer but would be bulky.Oh- the only parts the factory carried was output transformers and power transformers-the outputs were $400 each and the power ones were $200 each.Didn't need those.I have tried looking thru the part "junkpiles" at old radio stations-no luck.
 
I can get the values and volt ratings.They are marked on the caps-mounted on the chassis.The power supply voltage to the 6550 output tubes was around 475V.I think its the bypass sections in the filter caps and the cathode bypass caps that are going. Severe oscillation.I have encountered similar problems in Ampex 300 recorder record-play amps and a CCA AM tranmitter modulator exciter.Replaced their bypass caps and they were OK.
