sundown audio SAz-1000D

Does anyone know the value of this resistor?
its labeled R22 and is beside CB6.

 

[Perry Babin]

maybe 47 ohms if the RC network connects between the output drains and the speaker negative.

I dont have a schematic for this amp. Any reason why this resistor would burn through. the audi outputs and powersupply fets are all testing okay in the circuit.

 

[Perry Babin]

Did the cap short?

 

[Perry Babin]

Your amp output stage is 1/2 of the attached amp. It appears to be R226/R256.

 

[RockfordFIx]

it doesn't read short in circuit but it is definitely damaged from short or resistor igniting and burning next to it. the resistor was nowhere to be found.

I can see a few pics online and they are hard to make out but the yellow is definitely identifiable and some pics have the violet as the middle band. I think you are right perry about it being a 47 ohm resistor but 2 or 3 watt.

 

[Perry Babin]

The diagram says 2w.

thanks perry you are correct! the cap on the board correlates to schematics too(m102j).

Greetings RockfordFIx, i have an ongoing thread with a similar amp (SAE-1000D) and i dont want to start a new thread, could you tell me the values of your output capacitors you have on your board CE6, CE26 and CE29 (near the relay) and post a detail pic of that area? thanks.

the cap values are 250v 10uf capacitors.
