You could use Earth and neutral, I'll bet they didn't.

That would work but there's a risk that a new collector could still think it was operated on mains power and plug it into an incorrectly wired GPO or worse still one of those mirror-reversed double adaptors. Unlikely, but still possible.

I would always strongly discourage the use of a mains plug top for anything that operates on extra-low voltage (ELV) - as GTC mentioned, there are plugs and sockets for use with ELV. The one he linked to is wired + to the horizontal pin and - to the vertical in all states and territories except Victoria which for some reason states the opposite - don't ask why that is the case, I couldn't begin to guess.

These special purpose outlets and the plug tops to suit them are available at electrical wholesalers.

As a general rule, when I sell a radio or other electrical item and cannot guarantee that the product is restored and working I always cut the cord off and put in a message stating that the item must be serviced or restored by a competant person before being put into service. I've been bagged by other Ebay members for cutting cords off but the problem is that these people will be the first ones to sue me or another seller for not informing them that old items can pose a danger or because they'd assume that if a cord is fitted then it is okay to plug the item in no matter what.

Self preservation in this world of frivolous litigation is a good thing.

As Brad has suggested it is quite easy to get inversion of the Neutral & Active. The Americans. in transformerless radio's had a bad habit of putting a cap from mains to chassis & I have had examples of that sort of dangerous thing here.

The regs here clearly state, that if a metal part can become live it is required to be connected to the earth. which means you could still get a punch through & blow it up as neutral is normally earthed anyway.

The bottom line is that DC plugs are available and using mains plugs for the wrong application can have serious ramifications.

...as neutral is normally earthed anyway.

Yes. At the main switchboard in all electrical installations the neutral wire is bonded to earth resulting in the multiple-earthed neutral system.

Just got this reply from seller:

"Thanks Mate, I will cut it off, cheers for letting me know"

Seems good sense has prevailed.

Good result.

Hello Art, et al

I too have acquired an RT 60 TM and discovered Art's posting that he had got hold of a circuit diagramme and other information. I too would like to obtain a copy and may resurrect this "beast" I am a licensed radio Amateur so I can put it on a legit Amateur band.

Looking at the devices incorporated (TO-3 transistors like OC23's, 2N301's) takes me back a long way! I was a radio and TV apprentice back in the late 60's in Western Australia

Kind regards,
Denis

Haven't seen a post by Art on here for some time. It may be better emailing him direct. (Click on his member name.)

Thanks GTC

Shall do.

Kind regards,
Denis
