I've ordered some Z700U tubes from this seller as well now - thanks for
the lead. Do you want to swap design ideas and layouts (I use Eagle)?
I have posted the question here in case anyone else is interested as well.

Some XC24 did go on Ebay - perhaps a year ago now - I missed the auction
totally but did ask the vendor if he had more but alas not. However,
your suggestion Nick, of using a pair back to back does work fine. In
