TSL100 Replacement component questions

[Lee_ranaldo]

I heard these amps have the "bias drifting issue"
sadly i replaced the resistors with stock values and sizes

My question is.
Do i have to replace those with larger capacity resistors.

The board doesn't have signs of overheating but a previous tech installed
larger capacity resistors with different values.

I also replaced C46 capacitor with a 500V 22P Silver Mica one.
Does this HAVE TO be 1KV at least?

Thanks in advance..

this is the new board with metal film resistors
it doesn't suffer from bias drifting. but these resistors (in the bias section) were replaced.

i'm fittting 1/2 Watt Resistors. now.
