Resistor replacement

Hi I have a 5050 and when I took off the bottom cover to access the f-2646 board to clean the pots, I noticed a burned up resistor in R14. I found the same resistor on R13 and it is a 33k ohm resistor.

when replacing this, what type of resistor should I replace it with? 1/4w metal film? And would I need to replace the R13 one too to match it or not necessary?

thanks

A more important question to ask is why did R14 burn up? That is part of the bias circuit for TR02. If R14 is open it will certainly throw off the operating parameters of the circuit.
I would check TR02. I'm sure a Sansui expert will chime in on the Resistor rating.

The 5050 manual I found online does not show what rating R13/14 are. I think (dangerous) Sansui uses a standard value and only notes deviations in the parts list, but I could be way off base.

That said, based on the schematic it looks like 1/4 watt would be OK.
 
To be honest i got this 5050 in a non working order and replaced all caps transistors etc, I may have missed this burnt resistor while performing the restoration.
