prices of marginal units linger in the triple digits,
and monster receivers are out of reach.
Recently deals have been rare.
but a quick Friday walkabout found this,
a scruffy $35 Pioneer SX-580.
perfect for an outside work setup,
needed since I gave away the little Kenwood.
A quick vac & brush left it really clean.
Lights on and clear sound,
not bad for 1978 era!
The 1971 Sansui 2000a was ok,
but a little hissy when warned up,
most likely a recap needed.
I had also hooked up the Sansui qrx-8001,
and there was a light hum.
An issue with too efficient speakers,
magnifying the faults in the system.
to crank small wattage amplifiers,
in the 3-5 watt range.
The little pioneer actually sounded just fine!
A smooth tone with a bit thumpy bass,
but at least no underlying hum.
sound dead in one side.
A morning email went unreplied til night,
and I rushed out the next day.
even with the original box and remote!
A bit dusty,
maybe I'd get lucky and it'd just need cleaning...
just the components.
Mysterious black boxes replacing transistors.
(behind the volume and tone knobs)
The underside was one big circuit board,
not much to do there.
making it easy to test
if the amp or preamp was faulty.
the problem was in the amplifier section.
Like that would help me!
There were no obvious burns or bulging caps.
I started wiggling wires while it was on.
Yeah dangerous I'm sure....
But...Hey...there was sound!
The main amp plug was loose!
The fix was twisting the wires one turn more,
creating force on the plug.
Reminded me of the kid
blowing into the playstation plug to get it to work!
Hooked up it sounded very new,
no more tube-like warmth,
a crisp clinical sound with distinct separation.
Makes mp3 recordings sound like a$$!
And the best part is this new fangled remote!
The volume knob turns with the button,
I'm sure that was a huge selling point.
Good enough for now,
giving time to fix the oldies...
Now where to put the box!?
