Threshold CAS-2 Burnt resistor

[JED123]

I need to replace some broken resistors in my CAS-2 power amplifier.
What i can read from the colour codes, see attachment.
10 ohm tol 0,02%
0,68 ohm tol 10%

In need help some help finding the correct resistor?

Should i change them all of the or only the broken ones?

Best Regards

Braun power resistors look like carbon components but they are probably wire wound type ?

The WIDE blue band indicates a WW resistor. The 10 Ohm resistor with it's normal bands is just a Carbon Comp resistor.

Imho better change them all so both sides the same update with new resistors.

Can I change from WW resistor to Carbon or Metal film?

Great, Thanks
Mouser had alot of different resistors, but they look really cheap comparing to components from AudioNote, AMTRANS, Kiwame, Jensen etc. How do I know they are OK? From earlier repairs I now changing components can do huge changes to sound quality.

Don't waste your money on boutique resistors, especially where these are in the circuit. Mouser's parts are easilly as good if not better than the boutique ones.
Just make sure the power rating is at least as high, and watch the physical dimensions.
FYI - if those resistors are blown, so are the output transistors they are connected to.

Thanks Dan,

So I also need to find replacement transitors.....
Should I change all of them or only the one connected to the broken resistor?

if you can find exact transistor type, matched to existing ones, then you can change only that one

if not, you know the answer

just in case - you did test that transistor, at least with diode tester?

I had peculiar cases before - transistor good, while emiter resistor toasted
