Hey Chris,Very jealous!!
I wish I could find a 230v low capacitance IT here in the UK. I haven't been able to find one.
Is it really the case that only these Topaz (and other names mentioned here) have the low pF?
There are various companies that make toroidal tranfos (airlink etc) and balanced power supplies but they don't have the very low capacitance and thus have less noise rejection.
I was thinking about just getting a toroid and making a small box with IEC socket on one side and plugs on the other but couldn't find a transformer.
Jealous ! And well done.
I too need a 230v (with terminal) variant. Let me know when you find a supplier. I'll do the same if I come across one
