Last week I decided to take a look at a phono that my mom has been storing in my basement for 15 years. I knew nothing about old phonos, it even took me a while to figure out which way the lid opened, but there was a cylinder on it so I ran it for a few seconds and it seemed to work nicely. I didn't know it at the time, but the phono is an Amberola 50 that had been in my grandmother's family since it was new and hadn't been played in over 40 years.
I've found some good information on the internet on compatible cylinders and caring for the machine, including a nice video by TheVictrolaGuy showing how to oil it (I used sewing machine oil). The spring that suspends the horn was missing so I put a new one in and the horn now hangs freely at the same height as the reproducer connection.
I was pleasantly surprised to find this forum that seems to be very active. I've spent several hours reading through it, a lot of them on threads that had nothing to do with the Amberola 50 but I just found interesting. I still have a few newbie questions that I hope you don't mind me asking ...
I didn't crank the phono when I first started it up or the next few times when I ran it, so it had been stored for 40 years with the spring wound, presumably pretty close to full. Is it best to leave the spring wound when the phono is not in use, say for 7 months?
I have run the spring to where the cylinder starts to slow down a little, but not all the way down. Is it good to let the spring run all the way down periodically or, conversely, should I avoid running it all the way down?
A couple times when playing, there has been a loud sound from around the governor that sounded like a spring was quickly unwinding, but it only lasted a second. The cylinder playing was unaffected and the rpm didn't seem to fluctuate. Any idea what that could have been? I think I've seen where there are 2 springs driving the motor. Could the noise be from it transitioning to the second spring?
In addition to the cylinder that was stored on the machine, I have 150 loose cylinders stored in two boxes. I found some info on cleaning them and used distilled water on some, but for the most part they have been sounding garbled. Many won't slide all the way on the mandrel, and I have seen info on using a reaming tool, but I thought I could still play them a little bit on the part that was on the mandrel since the rpm would still be the same. Does that not work? Does the cylinder have to be all the way on?
Thanks, and sorry for the long post, I won't make a habit of it
