Could you give more information? RadioShack has made
at least three
different products with that catalog number.
That is all I have. Just a sticker, basically saying to use the 270-1551.
Okay, but.. like, does it plug into the wall? A cigarette lighter?
Does it take the modern "Adaptaplugs" (the ones with two pins on them),
the older friction-fit barrel style, or is it one of those "four plugs
on the end of a wire, with a 9V clip" dealies?
Again, usage of basic tools that anybody who is even remotely serious
about collecting this stuff (a $5 voltmeter) would likely answer your
question for you.
Please, before you fill up this list with your rant at him, could you do
Will - and the rest of us - the courtesy of reading what he wrote.
A multimeter will not tell him the voltage or current of the supply,
because he HASN'T GOT the supply.
What he has is:
- A piece of kit he wants to test.
- A sticker on this kit which says that the supply it requires is called
270-1551.
- Various power supplies he might use to power it.
He has stated that (a) he doesn't want to buy C cells for it and (b) the
battery terminals are so arranged that it would be difficult to connect
directly to his bench supply.
Rather than break open the case (this is presumably a sealed unit), he
has asked whether anyone knows what voltage, current and polarity the
machine would expect from a 270-1551. Armed with this information, he
can choose a suitably rated supply and set it to deliver the right
voltage at the right polarity.
I can't answer his question, but I think it's a perfectly reasonable one.
(That said, I'd probably buy some cheap C-cells from the local pound
shop. Or even some decent C-cells for stock - they're bound to come in
handy.)
