I'm planning on building a C12(ish) mic & have been looking for places to get the 30M, 250M resistors from wthout having to buy 5000 or spend £20 on each. Anyone point me to some suppliers ?

Farnell and RS offer the best deals in the smd line...
I had to make up some odd value hi onmic resistors.... use the low price 5% types to make up the value you want
...mount on a little piece of veroboard,(can be made QUITE small ) ,add a couple of legs then coat in epoxy or pcb lacquer and bobs your uncle.
No discernable difference !
Or pay a high price for the 1% types...ouch

CIBA have always used their best stuff for Araldite (what you buy from a European hardware store). The Yanks didn't always do this.Rob Flinn said:An interesting concept, but I'm guessing you would need to be a little careful about what board & epoxy you're using, since at hi Z they could affect the spec ?
You need to be careful with ancient high value resistors.0dbfs said:You can also get some TRW carbon glaze resistors from ebay if you want some older NOS parts.

At Calrec, we had serious problems finding a reliable source in da old days. Many old high value "resistors" didn't obey Ohm's Law but were more like crappy diodes.
Modern high value resistors are MUCH better.

Yes. And this limits the max. spl and distortion performance in many common circuits. :'(gyraf said:Many cheap condensers (e.g.electrects) use a reversed diode as high-ohmic grid/gate resistor, depending on leakage current.
