HI All
Odd thing happened at the Market today. We had our 'pre-Christmas' Market - so muggins here volunteered to bring along some PA speakers and a little mains amp to provide the necessary 'Christmassy' music....
The amp in question is a little 25+25W Mosfet hi-fi amp (ETI, years ago, if I remember rightly) - which I'd been running in the studio for the past week or so, just to make sure that everything was working fine....
Ran an extension lead from the big, Land-rover-mounted, genny that the meat & sausages man runs. He uses it every week to operate some sort of a chiller system built into his trailer .... allegedy 240v and (judging by the size of the genny) loadsa amps...
So - cabled it all up, turned on the mains.... and..... nothing ! Mains in to the amplifier is via a conventional toriod, into a bridge rectifier, then feeding a front panel led from the +15v rail. Led didn't light......
Only had a little mains-tester screwdriver - which claimed that there was something 'live-ish' going into the amp. Oddly enough, the neon indicator on my little weller soldering iron also declined to light, when plugged into the power from the genny..
Gave up on the music thing - and used a portable CD boom-box instead.
Got back home, plugged in the amp - and, would you believe it, it lights up and behaves impeccably.....
So - any bright ideas as to what might have been going on with the genny ? Be nice to understand it by this time next year when we have our next pre-Christmas market....
Any generator experts out there ?
Thanks Adrian
