[sdiy] is this PSU OK?

OK, I think it is some glitch in the scope, but I am not sure since I don't 
know these things very well.   

I am using only one channel, although my scope does have chop and alternate, 
I am firmly in one channel.

I removed the 10uf caps from the end of the supply and the chop went away.. 
for a little while, I accidentally nudged the calibration pot that is on the 
knob of volts/div and it came back, I moved it back to where it was but the 
gaps continued.  this is why I think it is something with my (very old) scope

then I switched channels and there were no gaps.

thus my dillemma, 

which channel is right?  

I seem to feel that the problem is not in the circuit at this point.  

Harry, No I am not sure I want to connect the mains ground to 0V,  it just 
feels dangerous to me, (especially so after you just said about it!) I said 
about it in case it had some bearing on this problem.  

Oh and this doesn't show up when the probe tip is grounded or with the 
scope's test signal.

i have a 5x sweep switch, and it was off at the time of the 3ms observation.

I guess it in't something to worry too much about, 

my filter and LFO seem to run very well on it, I think it just means that my 
VCO's have some other problem ;(

thanks for everything guys, If I find anything else out I'll report back.
