Standing Current for PSW2010 Kef?

matt09 · 23rd February 2009, 10:27 PM

Hi there,

Recently restored a PSW2010 to working order but I am having problems with the standing current being too low and need to know the value, does anyone have an idea or does anyone happen to have one of these lying around to measure the standing current, at the moment the regulator wont work because the input voltage is too high due to the low current draw (shameful design flaw on behalf of kef).

I have tried emailing KEF and was provided with a service manual which gives schematic only.

Thanks.

Hi,

What sort of output stage does it have ? value of emitter resistors ?

Hi,

I did find the PSW2000 service manual.

The standing current is preset and has nothing to do with
the operation of any regulators in that particular layout.
