resistor size problem

post #1 of 3
Thread Starter 

Hi and thanks for reading this post.

I have a few blown one watt resistors i want to replace in my power amp and have been on mouser, digikey, farnell etc but cannot find sizes small enough.

I have just 8.5mm in width on the board so am thinking about using surface mount resistors as these are available in smaller packages.

Do you think this is a wise move switching from through hole to surface mount, has anyone done this and what are your experiences concerning sound quality changes.

Many thanks in advance. John.

Going SMD if you can improvise shouldn't do any harm, I think.

As long as the resistors you put in are rated at 1 W then okay.What you could do is parallel up some smaller wattage resistors to the value required [must be all same value  ] to spread the current equally over  them.eg= 120 OHMS-1W= 2 -240 OHMS at 0,5W in parallel.
