Good for parts?

IT'S HERE!!!!

50 SOME YEARS LATER...

The Sylvania Exponent 4 40 showed up yesterday to my surprise (a day early).

Unboxed it and it was very well packed for delivery. Super Job!

It is every thing I remember from the first Sylvania record player. It sounds amazing and the condition 

is A- / B+ . I am very happy with everything.

All the accessories (speaker cables, power cable, turntable spindle, changer

spindle, 45 singles spindle, new stylus) are in a bag inside the unit. I

also included the original parts that I pulled form the unit (minus the old

idle wheel).

Set-up: screw the 2 transport screws all the way in at the record changer

chassis (I marked these for you). Pull the blue foam pad form underneath the

turntable platter.

Install changer spindle (push in until it clicks into place) Power cable.

Speaker cables. Switch settings: selector to phono.

I hope the unit finds you well and is all you hoped for it to be.

 I remember when finished refurbishing I listened to your amplifier and thought it was one of the nicest sounding solid state amplifiers I had heard in a long time - I remember the sound being pretty close to tube - with lots of detail.
