Hi Yall,
For the last three years that I have owned my Saunders 4550 XLG enlarger (which I love) I notice that sometimes the switch for the power supply emits a big blue spark when I turn it off. The power supply is also connectec to the Saunders ET500 timer. I notice that often if I turn off the timer first and wait awhile, then when I turn off the power supply, there is no spark.
The manufacturer of the power supply tells me he has not heard of this problem before, but the LPL did change the design of the power supply some time ago by putting a capacitor somehwere in the circuit, but he wasn't sure why. The US distributors of this enlarger have no knowledge of any of this.
So anyway, has anybody had a similar sparking problem with the switch to this power supply?
Thanks and Happy New Year
