No I don't have a replacement. What is its function in the circuit?
I have a limited assortment but no surface mount resistors.

If you have something near 1k ohms, connect it in series with the cathode. Short the cathode and reference. Connect the resistor's free end to a 12v power supply. Connect the anode to the 12v PS ground.
What's the DCV from anode to the cathode/reference node?
It's used in the bias circuit.

I pulled the TL431 and did the test. I measured 2.5vdc A to bridged C/R so it seems to be working correctly. Soldered it back in and still am only measuring -.18vdc A to R.
There appears to be an defective component. The 10 ohm resistors were the most common. You'll need to do it the hard way and check all of the small components.
These amps are not like most others in that you can't remove the smaller transistors and power up. For most amps, it won't cause a problem. In these amps, it can cause excessive current draw.
