Full ACK :D. I once repaired a mic cable. The so called 'audio engineer'
who 'repaired' it before I did it, didn't know what a 'balanced'
connection is, he thought 2 cords and 1 shield must be a stereo cable
for a stereo mic. What he wanted was a connection that fit the mono
microphone to a 6.3 mm stereo jack for a consumer cassette recorder.

I don't think that we need to worry too much about the frequency. In the
morning, when all the people turn on all the coffee machines and
toasters, might be a bad time to adjust the H/V deflection for a
television set, because of the voltage that differs, but the frequency
should be stable. But indeed, during a snow storm the frequency will
drop extremely, but if so, we will hear about power blackouts in the
radio news, this happened e.g. in 2006 in Western Europe, there we had
around 49 HZ.

I guess even if it's OT, it's important. We won't a Hammond B3 become
similar to a tuning unstable Minimoog.

Indeed Veronica and Gene, I guess Fons is right. Yesterday evening it
wasn't 49 Hz, but a bad measurement done by my supermarket meter. But
who knows? Maybe the frequency really was down. Regarding to station
clocks I guess they are synced by radio and not by the power line. In
Parma there the clocks might be heritage-protected ;) and stills synced
by the power line frequency.

Cheers!

Listen to Jasper van't Hof and Achim Jaroschek | Campus inter|national
#39 today in Leipzig
I can't be in Leipzig myself, but I saw some rehearses on video, when I
visited Achim and I'm sure it's worth it to visit their concert.
