Nonetheless, touch sight and smell are legitimate electronics tools. Common wirewound sand cast resistors are also quite rugged, often surviving enough heat to cause discolouration, not that that's a good thing.
Yes smell is often the first sign that there is a problem, resistors will start to smell well before they smoke. I use the finger test all the time (approaching with caution). Too hot to hold may not indicate something is beyond it's design limits, but it does indicate that perhaps a higher power component may be appropriate! If things only get slightly warm then its a pretty safe bet they will have a long life 🙂

True, but I'd rather simulate and make sure I have plenty of overhead. For instance, I like to simulate at full power and upgrade anything that remotely comes close to it's limitation.
Listening however I can't take it for very long, so I worry the resistors won't get hot fast enough for me to tell.
So, I guess you could say I'm doing a little overkill, but then, my resistors won't degrade like I've seen in some commercial speakers.
Best,
Erik
