Isolating a "hot" chassis
 
Is there a way to isolate or make a hot chassis radio like a S-38 or a S-77
safer other than using an isolation transformer?

Yup. Completely embed it in concrete. grin

For the original S-38, which has a hot chassis and isolated
outer metal cabinet:

Be darn sure the chassis to metal cabinet AC bypass cap
is replaced with a UL line-bypass-rated capacitor to start with.

Second, replace the two wire cord with a three wire hot-neutral-ground
type. The AC switch should break the hot lead, not the chassis return
side of the cord. The neutral should connect to chassis, the hot lead
to the power switch--but make sure the set is wired to break the hot
side, NOT the chassis side of the line as done in many AC/DC sets.
Of course the green ground lead should go directly to the outside metal
cabinet.

Verify your house outlets have been wired according to code.

Enjoy the radio.

It is difficult to answer your question if you do not give us a return
address that works. You have a "no-spam" e-mail address and it is too much
work to go around it.

I answered your question, but it bounced. Too much work to type it again.
If you want a response, make it easy for the responder.

Whoops - wrong post. This should have been for a different post and not
this one. Colin K7FM
