Missing a Resistor?

[Todzilla]

A little confusion assembling my A12.

Resistor R19 (1M00) is not in my order. Bill of Materials lists it, but with a quantity of zero. I will be using Op-amps, and instructions say to not install R20 (same kind as R19) or R22. However, instructions say nothing about leaving R19 out.

Please clarify.

thanks!

See the chart on page 17 of the assembly instructions. R19 is 1M only if you're installing the DC servo option. Otherwise, it's a 0 ohm jumper.

Thanks much Tim. And the zero ohm resistors are the tan guys with a single black band?

I assume you're cringing in wait for me to return my defectively assembled unit.

So far though, I think my unit is coming along well. FWIW, I've built a PAIA tube preamp and outboard EQ unit, both of which worked fine first try.
