CTC9 troubles

[radio63]

If you had a CTC9 and wanted to make the set safer and more reliable, and the AC jack was worn out, would you replace it with a two or three prong IEC power entry jack?

In my humble opinion, I really do not believe you should install a 3 prong or 2 prong IEC jack on your CTC-9. Nor should you make any other non-reversible modifications. You will be ruining the originality of it. Since you are concerned about safety, I would suggest doing something along the following lines:

Build a separate outlet-box with a duplex receptacle at the end of a sturdy three-prong power cord. Wire the outlet box with fuses and any additional safety items you wish to use. If you get a dual-type box, you will have enough room to wire in the fuse holders. Plug this into a power strip, surge protector or any other safety device you wish to use. Plug your TV into this box. If you really want the chassis grounded, you could run a separate wire connected to the chassis and the outlet box unit you will build. If you plug this into a grounded three-prong outlet, this will ground the chassis and you will not have modified the chassis irreversibly.

You mentioned earlier that you thought the original cord was rather thin. If that is the original cord, then that's what the manufacturer specified for that receiver. It should be adequate to carry the power load required for the set.

Just a suggestion. I understand your concerns but I feel it would be better not to do anything to it that is not reversible.
