R205 100 ohm resistor in SR98 starting to get hot and smell

[exxos]

Question for Exxos - there is one cap left on the board C206 that does not have a replacement (see cap with dot on top in pic).
Does that also need replacing or is it worth replacing with a new one?

There is a huge thread on this somewhere, basically is purposely not changed..

I think the bottom line was, I tried ceramics, and all sorts on there, and mostly everything I did seem to make it worse if I remember rightly..

So oddly, it is actually better to leave that alone...

You got to watch those clips on the rectifier and heatsink. Mine just pinged off whilst applying pressure and hit the ceiling.

Sweet!

Just a note - the large rectifier the legs are a little too wide for the holes. Had to drill the original holes a fraction bigger to get the component in.

Thanks Exxos - You are always one step ahead

Power lines under load before metal film resistor replacement:

+5V line= 4.85V
+12V line= 11.26V

Power lines under load after metal film resistor replacement:

+5V line = 4.84V
+12V line = 11.23V

More importantly R205 is not getting really hot and smelling. Thus have solved the heat and smell problem.

Finished measurements (under load) with metal film resistor replacement and recap:

+5V line = 4.92V
+12V line = 11.09V
