3 prong on ancient record player?

[drewl]

Put this one in the "odd stuff we repair" thread.

Old 60's tube "stereo!" record player, would you put a 3 pronger on it?

No exposed metal parts, but I'm thinking yes for safety.

No exposed metal parts.

Therin is the rub.

I wouldn't bother.

[R.G.]

Yes. It's pretty sure that the output jack grounds are "accessible metal parts" and those ought to be hard-wired to line neutral unless you already know that the insides meet double insulation standards - which, in the 60s, they didn't.

Or, if there are no output jacks, the speaker leads/etc. will be accessible, unless they are purely transformer coupled, and if the trannies will stand 4kV for a minute between primary and secondary.

'No exposed metal parts'

Even the turntable spindle? Grub screws on the control knobs?

A better description of the unit would help, is this an all in one unit with an line powered filament string amp?

Of course, a Magnavox chassis # 80-01-00.
One 12AX7, two 50 E something 7pin drivers.
The snobs at the Radio Museum have the schem but you have to donate money for it.

Got it working, just cranking some VH on it to the amusement if my son.
