And here I am with perpetual OT. Sorry, George. Just for quick confirmation, are you happy with your scope? BKSabath here would have chosen otherwise if time traveling was invented.
I am happy with the scope, no problems. It does its gob. Also has a primitive signal generator, so you don' t have to buy one immediately. I saw what Sandro said, but I would not recommend a digital one as a first scope.
You won't get the real time waveform update, the low noise trace and the gradual shading that phosphor analog scope will give you from entry level DSO mind you.
You have to trace it first. Try a fat carbon on the grid is one thing to see if its your signal wire that goes antenna on some freq. For the OPT its usually not ringings in the low Hz area, they are much higher but they can interact on the lower frequencies.
Jones makes a Y split with caps to ground over the choke. Filter chokes almost always rings at some freq but thats not so bad as when the OPT (which is the last filter choke in a way) does it cause you have no more damping after there. You might try with parallell caps from 10 pF up to, I dont know,.. a couple of nF to see if you can see differences.
We are team chasing the elusive wiggle. Nice, I like it.
When Im done with my CF Im gonna take it as hand-baggage down to Poros, ok?

You are welcome any time, especially with nice hand-baggages!
I tried with carbon resistor, no change.
Regarding OPT, the LL1660 does have some nice ringing in the 50kHz region in my #26. After that, these chokes look nice!
