Does anyone know where I can source ceramic stand offs? The type used for raising large resistors etc above board level. Ideally 10-12mm tall 5-6mm dia with a through hole (not threaded). Thanks.
You might try these, and use a high speed carbide drill bit to make a through hole.

if you can part out an old Tektronix scope there are ceramic strips on which most of the resistors were mounted -- of course you should use silver solder --
Look at this ebay listing:
ceramic standoffs
It seems he'll supply larger quantities. I intend to order some.

Shop price for the ceramic standoffs on ebay posted by John is in the order of £ 5 for 10.
If you are thinking of ceramics standoffs for boardmounted resistors, there are ceramic pearls that can be stacked to desired height.
Small size: 3x3mm, 1mm center hole, about £ 2/100
Big size: 5.3x5mm, 2.3mm center hole, £ 2.70/100.
I've bought those wholesale in Germany.

Ah,
Just realised that I didn't read the original post correctly and recommended the wrong type, sorry.

Pardon me, i've posted the name so often it feels i am advertising.

Private persons can buy direct at their stores, internet orders need not be big but you need a company account number.
(For EU shoppers it is pretty cool if a company VAT number can be supplied, for orders up to a number of 100s of Euro's no VAT is paid. Not there, not here, in my case saves me 19%VAT)
If none of these are an option for you, you could look for a German member to get it for you.
(or have the patience to wait for someone with 10 different tongues till i am ready for some new parts, not so long ago i got parts from them for me and Gengis in the US)
