Anyone have pics of this area?

And know the value of D91?

This is someone else’s Handy work on this amp burnt pads missing parts .

 

[Perry Babin]

This is the basic generic circuit that this type of amp uses. Where is D91?

Possibly in parallel with R91?

 

[caraudioguy2100]

D91

 

[Perry Babin]

Possibly in parallel with R91?

 

[caraudioguy2100]

Yes it’s in parallel with R91

 

[Perry Babin]

My guess would be a 1N4148.

 

[caraudioguy2100]

So is R91 a 820k ?

 

[Perry Babin]

Is it connected as shown in the diagram?

 

[caraudioguy2100]

The one that came out of the amp measures 1.2m ohms .i can’t make out the first color band tho .

The 2nd band is red
3rd band blue
Fourth band gold

 

[Perry Babin]

Are you sure the 3rd band is blue?

 

[caraudioguy2100]

The more I look at it it appears to be green

 

[Perry Babin]

It could be 1.2M. 820K would have a yellow stripe.

 

[caraudioguy2100]

Does anyone know the value of the power supply filter caps ?

 

[Perry Babin]

It appears that they are 3300uF 25v 105c. This is not definitive but I think it's right.
