Hi,

NOOB ALERT!!

I'm making a 'Fabio' Reliquia 312 (API clone)

It's 2 preamps in one case - with one power supply.

It's my first ever electronics project so please keep any replies in plain English (for a beginner - thanks!)

So, I need to know the values for resistors R1, R2, R10 and R11.

Is there some way to work it out from the values of the other components I'm using?

Here's the parts list so far:

OP AMP = gar2520
SERVO & U1 = OPA604
MAINS TOROID TRANSFORMER = CA-18-VT31284 (Primary: 110v-0-110v / Secondaries: 20.95v-0-20.95v @ 0.27A and 50v @ 0.023A)
RELAYS = TQ2-5V
INPUT TRANSFORMERS = Ed Anderson EA2622
OUTPUT TRANSFORMERS = Ed Anderson EA2503

(Will be wired for 220V Mains)

Any help, suggestions or warnings much appreciated!

Many thanks in advance.
