Subject: seeking an amplifier



            Dear andy,

Could you please distribute this to the HAMS List for us.  Curtis Delzer is
looking for an amplifier and perhaps someone could help him out.  Please
Read Below.

 

I need an audio receiver, or an audio amplifier with simple tone controls on
it. It would be used in the production of accessible world shows where the
interviews take place on the phone lines, to be broadcast over the internet.
I have been a ham operator, (like Rick), :) since 1963 when devices like
this were as common as external ham radio speakers. It is a "phone patch,"
and as such, is designed for the purpose that the "phone bridge," is, for
the idea of taking a received ham radio signal, putting it over the phone
line, and taking that phone line signal and putting it over a transmitter,
up to a thousand watts. For probably 2 dozen years I have used this device
and made several hundred "phone patch" calls from men overseas to their
sweethearts and wives / children at home, where I'd make the collect call
from my location in Lodi, California to their wives  . . .  and patch them
into my conversation over, usually, 20 meters ham band to the ship at sea or
the remote location on, oh let's say, Johnston Island, for example. It,
should, for all practical intents and purposes, be the same except the
signal conditions would not vary except what you hear over the computer from
variable audio quality, and if I had a decent 4 or 8 ohm source, I only need
plug it in, and voila! Much less complex than any phone bridge, 2 computers,
etc. where all I need do is "key the microphone," and they could be talking.
:)
Now, you know a little more about what I have been attempting to do. I have
a receiver, but this pioneer I have, it's speaker connectors are of a type I
have never seen before, looking like a combination spade lug and pin
connector. What I need is some kind of amplifier, not complex or heavy, with
conventional "wire lugs" or those spring loaded connectors for speakers,
with tone controls to drive the speaker / phone patch, to a decent volume,
probably 20 watts would be hugely more than adequate, and our problem would
be 95 percent solved.
