mystery purchase of the day

pango · 4th December 2006, 06:22 AM

Hi folks. Longtime lurker, but first post.

I was at a flea market this weekend, and found what looks to be a pre-amp. It was only $1.00, so I bought it. But I'm not completely sure that it IS a pre-amp.

One reason that I'm skeptical is that the seller also had a sign on an old SS amp that said it was a tube amp, even though you clearly could see that it wasn't if you looked in the grille. Admittedly, what I have looks like a tube pre-amp. But a lot of devices look like tube-preamps.

The photos aren't great, but I tried. There is one RCA jack on the top, and two black jacks, one with 3 small slots and one with 4 slots, towards the edge.

I'm a bit leery about plugging it in and starting to attach signal generators and the like into it, as there's no power or isolation transformer, and I'd prefer not to be killed for the sake of what might be a 1-dollar piece of junk. Unfortunately, no brand or model markings anywhere.

Any opinions on what it is, and whether I got a deal or just blew a buck?

Thanks

sorry, I'm having trouble uploading the jpg. It's well within the size restrictions, but it never shows up in the preview screen or the final post, even though the filename shows in the "Attach File" dialog box.

Am I doing something wrong?

Don't use the preview option, it sometimes breaks things.

Thank you pink mouse.

Let's try this again

Hi.

I'm sure you don't have to be told :-

DO NOT PLUG IN WITHOUT USING AN ISOLATION TRANSFORMER !!

It look like a record player / organ / radiogram amplifier.
