Granny's Console

Can anyone tell me how old my grandmother's Magnavox console is? The serial number (maybe model number) is 1sc277f

'bout 1959.

Thanks for the info!

I have one more question about it if that's ok. I've noticed that the amplifier turns on only when the turntable is spinning. They seem to be connected to the same switch so that when the record player stops, the amp shuts off. I understand why, especially since this model doesn't have a radio.

I was planning on connecting an RCA switch to the amplifier input so I could select between using the record player as an input and an external source with no modification required. This seems tricky however, after realizing that the amp power and the turntable are connected as far as I can tell such that in order to feed another source into the amp, the turntable would have to continuously spin so the amp would stay on.

Am I missing something here or is it true that there is no way to have the amp on without the turntable spinning. Also, if this is the case is there any chance of shortening the life of the turntable by letting it spin while using another source to the amp?

Not knowing that "set-up"--It would be my guess that running the motor for any long amount of time is "un-wise"--especially if it has not been properly "lubricated" in a long time. Also, on some players, the motor winding is used as a transformer to supply the power to the amp. If you have the skills necessary, you could "investigate" this, and if not the case, on this model, you could add a motor off/on switch--Ron Rich

I occasionally get customers asking me about "adding an Ipod jack" on some sets.
I can perform this custom modification in most cases.
However, unless you are thoroughly knowledgeable in electronics, and know the factors involved, I wouldn't recommend doing it, at the risk of damaging the external source and/or causing an electrically unsafe condition - AKA a shock hazzard.
