[FreeBay] Swap Nice Autek QF-1A audio filter for Ameco Pre-amp

Mon, 3 Jun 2002 22:31:02 -0000

Hello all
I have a very nice Autek QF-1A audio filter that I will swap for one of the
following.

Some specifics on the QF-1A.
1.  Analog Audio filter with Highpass, lowpass, Bandpass (for CW) and notch
functions.  This has the dual filters so that you can use the lpf, hpf and
peak functions AND notch an interfering hetrodyne/CW signal at the same
time.
2.  Maximum selectivity in CW  "peak" mode is 20Hz.  I find this filter much
more pleasant to listen to than most of the DSP filters as it doesn't give
that "digital" sound.
3.  Internal AC power supply so that you don't need to connect it to a 12
Volt power supply.  Factory instruction sheet tells how to connect to 12VDC
though.

What I want!

An Ameco PCL (or other model) Nuvistor pre-amp that covers 160-6 meters.
This is the little black unit with a copper colored face that Ameco sold in
the '60s.   Must be in good condition, but I do not necessarily need the AC
power supply.

Each to handle good packing and insured mailing on their individual units.
