Friends -- Along with some remodeling we've retired a nifty little (in its day)
panasonic receiver/tape-deck/cd-player which was the centerpiece of our modest
home audio/video setup. Now with all inputs going through tivo/apple-tv we
replace the receiver with an inexpensive amplifier (pictured) and have been
enjoying the extra shelf space this change made available.
That is, enjoying until now.
The Amazon reviews warned that this unit had reliability problems which I can
confirm. After a few weeks of service driving the panasonic bookshelf speakers
(4 ohm, nothing special) the amplifier developed an unusual oscillation:
Burrrrraaaap, burrrrraaaap, at maybe 2 Hz. I found I could squelch this by
turning down the base. I didn't miss the base, I'm over that phase of my life.
But now, another week has gone by and it has started to hum. It is a nice clean
60 Hz hum so I assume it is some related or not weakness in the built-in AC
supply. No control twiddling or power cycling helps and it is too small to kick.
I wonder if anyone on this list has a suggestion as to how to repair or replace
this equipment? I should note that I have at present invested sums equivalent
to my monday night bar tab. I'd spend more but not much more because after say
$50 all the money goes to unwanted features in bigger (and still empty) boxes.
If I can't find something good soon I might just have to recover my Dynaco
Stereo-70 (a David Hafler design) from cold storage in the basement. This would
not make Karen happy. http://en.wikipedia.org/wiki/Dynaco#Products
