flicker fixer issues

If think Stedy is on the right track - on what I can make out it looks like a power/grounding issue.

I was using a 500 PSU I do have a 1200 one so I will try that later to see if it helps although being as he advertised this for use with a 500 you would expect it to work!

I'm so glad I didn't buy that - I was really tempted until I realised I can buy the same hardware for $35, uncased.  I might buy that.

I bought another so-called scandoubler off eBay a month ago, and it's so terrible it's going back:

It's advertised as crystal clear conversion for a lot of systems including Amiga, but it truly is a pile of crap.  Pronounced vertical lines, artifacts, and no hardware adjustment either.  Expensive to post back to the US too - $30.  The unit is apparently set for EGA only, according to the technical people at the company in California.  Any kind of search for "Amiga VGA" on eBay will bring up their crappy product.  It's blatent misrepresentation.
