Hi Larry,

Ok, I'm sitting down.... I've always wanted to know.
How hideously expensive, if that's not a rude question,
was your big toroid ?  I've been wanting one (can't
afford it at the moment, at any price, anyway) but have
only seen the 8x2" one for the BTC3 at about US$70, I
think, and the 12x3" one is 'POR'.  I imagine the cost
rises somewhat exponentially with size ?  Was this an
'off the shelf' item, or made to order ?

Thanx,

Phil Chalk.
