Phono preamplifier - where to buy?
Aloke Prasad
cartridge.
Where can I buy a phono preamplifier to interface between my turntable
and my soundcard?
I have seen some mention of Radio Shack, but the local store has no idea
what I am talking about.
Specifics like part # or catalog number would be helpful.
Thanks

Could you provide a part # or maybe even a name to call this thing when
I go to the Radio Shack store again.. ?
The store had a paper catalog but I could not locate the item in it in a
few short minutes.

Hi, Aloke:
I have a 1999 Radio shack catalog. They show a phono preamp on page 126;
here are the details:
Magnetic cartridge stereo preamp. Allows magnetic cartridge turntable to
be used on ceramic phono or Aux input.
RSU10445161 $24.99
The RSU stands for radio shack unlimited, which means they have to order
it for you. I dont know what their turn around time is.
There are no specs, such as noise or distortion, etc.
Mind you that I dont know anything about this item, and radio shack is
not one of my favorite stores for electronics, though I do buy things
from them when I need them quickly or dont want to pay shipping charges
for a small item. Maybe someone that has used one of these units could
tell you how well it works.
Good luck!
Don

Don,
Thanks a bunch. If this converts a magnetic cartridge to be used in AUX
input, then I assume that this would also do any RIAA equalization, and
could be connected to the input of my Soundcard.
The trouble with special orders is that RShack may not accept any
returns :-(
I hope someone familiar with this gadget would chime in with some input.
Surely lots of people must be doing this (LP -> CDR)..
Of course I could dismantle my stereo setup and move the Receiver to my
computer room, but I'd rather not.

Wow. Sounds like lot of work. I'd rather move my turntable and buy this
$25 thingie.
Moving the turntable is not a big deal for me as mine was stored in the
basement, gathering dust. Luckily I still had the Discwasher brush and
solutions etc to clean the LPs one last time (hopefully).

There's one built in to any amp or receiver that accepts a phono input.
You can use that one by connecting the tape output to your sound card.

Radio Shack sells one via their mail order department - apparently
there's not enough demand to carry it in their stores. The order number
is RSU 10445161. It's $24.95. It may be battery powered, I can't tell
from the picture. It's on page 126 of their 1999 catalog.
I have one in my system that's made by Audio Alchemy. Unfortunately,
they're out of business. Many high end audio companies make them, but
they are usually rather expensive (several hundred dollars), and are
sometimes designed as an add-on to a specific model of amp or preamp, so
those wouldn't do you much good.

was competent. It is - $30 from the catalogue and (hooray!) runs on a
battery.

Try your local audio dealer. They have tons of preamplifiers, integrated amps
or receivers for sale that can handle the signal from a turntable.

I have had others tell me here that the item # is RSU 10445161 in the
1999 catalog, page 126 and that this is a special order item only.
Which year Catalog did you use? Was that a special order?
Are we talking about the same thing?

available...cost was about $100.
