Like this one,
Hung Chang 5510 Oscilloscope 100 MHz 3 Channel | eBay

They call it a three channel here... it is really in all fairness and it can actually display up to 8 traces if you put a bit of spin on the description.

That would certainly be nice. Wife and I have a kid on the way so no new toys until we find out what kind of $$ we are talking about with the kid.


Back to the PSU.

After adding 2200uf of smoothing everything looks much nicer.

Thanks folks for all of your help. I'm on to the speaker forums for help with my next dilemma.

That is looking better. Has it cured your hum or do we need to do a bit more work on that. Ideally it should be silent.
