I scan the local craigslist musical instrument section daily, seems alot of people can barely give most organs or pianos away [indeed, many are listed in the free section] unless they are high end.
/they eat up so much space, people haven't played them in years or decades, and most people would opt for something much smaller and digital that has more options and sounds - But very nice score if you have the talent to use it and the space to keep it, I imagine they cost in the $1,000's back in the day.
when my Mom sold her house and moved into assisted living, we had an estate sale and I was all too happy to see her piano go. That thing weighed like a million tons. I told the buyer to bring help when they were going to pick it up because I wasn't about to lift it again.
Actually, we discovered a problem that happened during transportation. We suspect it is the main power supply capacitor. There’s no way I can replace that by myself, too dangerous.
It is playable, but there will be a hum. Keep this in mind for the video demonstration.
My wife accepted one as a "gift". First time plugged in, and turned on, it tripped a breaker. So, I spent a couple days cleaning it out ( unbelievable ), found the obvious short, fixed that, plugged it back in, turned it on. It worked! A few sticky keys, but now we had a great big humming beast that gave off that hot tube smell. Nobody in the house knew how to play. My two little granddaughters liked to play on it, but it went away in a few years. Good luck with yours. They were, in the 50's-60's quite the status symbol, to have in your home. Very pricey.
