Hi Experts
I have an Energizer 4-unit AA or AAA battery charger that was designed for
220-240V 50 Hz, 7 watts.
What would happen if I used it on 230V 60 Hz?

Like to make an automatic AC line booster using a motorized 0 - 120 Volt
variable transformer,  ie Variac, Staco, etc.,  with 10 amp (or more)
current capability.  A Variac model M1010B or equivalent would be fine.

I was looking through some old notes on the Tek 547, and found
repeated references to modifying a CA so it would work with the sweep
switching in the 547. I even have an explanation of how it works from
within the 547 (it uses different pins from the 1A1) but I have no

Does anyone know of a devise or sensor that can indicate a signal or no
signal for a forward movement, but have a signal for a reverse

  I'm trying to locate the manufacturer or supplier of a copying
system, that does NOT use a PC, that will allow audio recordings made on

a non-rewritable CD for archiving.

I'm writing from Italy and I'm searching for Service Manual of Fluke

Does anyone know what it takes to use it, apart from a mouse of course?
Thanks,
