If I've understood the French correctly, pcbs are available from CIMKO for €3 + €2 postage. Google says the description means 'epoxy with printed chokes'.

Perhaps if several people were interested, it would be worth ordering a few to save on postage from France.
It will be interesting to see how much power it will run with sufficient linearity for DATV.
Postage to UK will probably be more, but it may not save much by getting a number of them and having to post them on from here.
Still no word from Cimko. I didn't think my French was that bad.
Talking to some folks in the know their comments were:
Important elements of the 'Test Fixture' are the use of capacitors having very low inductances. This is true for the 3.3uF - the ebay photo suggests it's a tant! Also L1 thru L4 are SMD inductors ( suggestion Farnell 2056515 - a Vishay-Dale product) and finally, build into the 'test fixture' 3 screens that separate the four inductors, and asociated components, from each other.
So yes, it is touchy and if there are some proven PCBs, I would definitely be interested in 2 units - maybe the BATC shop could do a bulk buy...
