Thanks valaerii,
I assume you alludeing to riken resistors, can you expand on that?, (ie why do you think there better than Allen beadley types?)

Sitll need some info on the o/p Cap if any one can offer any--ta!

OR, can i get away with out a o/p cap frim the I/V resistor if there is very smallD.C. offset-- a better solution if thats so ??

Try Russian Tefon, K72P-6 type o.1 uF.
You need high input impedance (FET-input) circuit after that though.
