I would like the part numbers of blown resistors I think they are 4.7ohms but diodes D8 & D10. IC9 & IC14
With pins 4 and 5 bridged, this IC9 has to be an IRS20957. The other others would be a 2092 or an SI8244 and it can't be those with 4/5 shorted.
IC14 ZXGD3005E6
Diodes D8 and D10 MURA120
Contact B2 audio and ask for the B2 Audio Riot 8000.1 diagram.

D8 & D10 Mr Babin is the glass diodes .5 watts (MELF) I presume, those are the ones I’m making enquiries about, and for the gate D29….?
D21 is T4 (parallel with 10ohms resistor)
D21 is T4 (parallel with 10ohms resistor)
Ok, looking at a different circuit, the drivers with the input to pin 6 are UCC27511.
The gate circuits are all very similar for this type amplifier. 15v Zener across the gate and source and a 1N4148 type parallel to a 10-15 ohm gate resistor.
Does the diode in question (D10) have any terminal connected directly to the 20957?
The burned resistors are typically 1-10 ohms. If you can read a 4, 4.7 is a good assumption.
What am I missing?
