Accurate Low Amp Current Probe Advice

<< < (32/56) > >>

Martin72:
I would have preferred an SCP5030, but it's not going to fit into my budget this year.
Probably not next year either. ;)

KungFuJosh:
I took apart the amp again and took better photos. I like the chassis design; it makes repairs easier.

Here's the electrolytic caps in the 503B:

35V 100uF    LS:5mm               x7
16V 220uF    LS:5mm               x3
50V 1uF      LS:2mm?               x1
50V 2000uF    LS:7.5mm D:16mm H:35mm  x2
50V 1000uF    LS:7.5mm D:14mm H:25mm  x2

Marked 85C

It looks like 4 of the caps were already replaced at some point.

Thanks,
Josh

KungFuJosh:
Here are my test results using the ET load.

I also did screenshots with the probe not connected to anything.

Thanks,
Josh

Martin72:
Hi,
Now do the same tests with "real" resistors..

What resistor values? What power source? I assume batteries, but specify which type please.

Thanks,
Josh
