Riken-Ohms ALWAYS an upgrade for Carbon resistors?

Anyone know if R24 on the AKSA 100W is a carbon resistor?

I happen to have some 1W Riken-Ohm resistors lying around that are of the same value.

Not sure if it is worth the trouble of swapping them out, however...

Yes, Benny,

R24 IS a carbon resistor. There's a reason for this!

A carbon resistor has an unmistakeable smell when pushed. This resistor is a bell weather item; it indicates if there is oscillation in the amplifier because of bad leads, horrific speaker load, whatever. We need something which will smell distinctly, and yet take a beating and hopefully survive. The metal film is less sensitive to this condition and doesn't smell so distinctly, and so I choose carbon just as Humphrey chose small birds to indicate gas in the coal mines.........

Cheers,

Hugh

Is that what they call practical engineering?

This is beyond practical engineering. It is an education device on sub human levels

Wow!

The more I learn about the AKSA circuit, the more I am impressed.
The design is truly ingenious! I will leave it as it is then.

Thanks again, Hugh!

riken ohms *are* carbon resistors; i'd replace it... i installed riken ohms in my art di/o, & it was a worthwhile improvement over the prewiously-installed holco metal films...
