Back in the day one of the strangest but really nice occurrences in my Hi Fi journey happened then.
My PL 700B blew up, taking out a couple drivers in my La Scalas.

For lack of funds at the time my rig remained
silent for a couple months while I saved up. Looking for somewhere to repair it I found a Pioneer-Jensen repair place
only a couple miles from my house. The amp was quite old at this time with half of the meter lights burned out, etc. I had actually bought it as their demo model from my local Pacific Stereo where I had drooled over the thought of owning it for a long time till it was replaced by the Series II stuff and sold at a big discount.
Anywho I got a call a few weeks later that it was done, so holding my breath I grabbed my checkbook and went to get it.
The counter man carried it out and set it down with the bill. I asked "How Much", to which the guy said No Charge. ???
I was dumbfounded and picked up the bill off the counter that listed a number of electrical repairs and included replacement
of
all the meter lamps, which I had even never mentioned, sure enough the in the bottom total column it was marked
NC
Never being one to look a gift horse in the mouth, I said thank you very much, picked up my Flame Liner and walked out.
I was sure there would be a call in a few days saying "ah, we made a mistake" but that call never came?
It sure was great not only to have everything playing music again but to see the ole girl running, even looking like new with
all the lights working again. Once in a while the Hi-Fi Gods smile on you.
For many years I also ran the stand alone "autocorrelation noise reduction" unit that was an internal part of that big 4000 preamp. It worked wonderfully at taking down LP surface noise, removing low end rumble, and perking up the dynamic range.
I much admired Bob Carver for his ground breaking engineering work in the early days of Hi-Fi.
