‘Correct’ power switch / fuse wiring

[Jay]

Several Youtube "Techs" like to pick on certain brands, not really sure why or what they want to achieve.

Surge voltages are quite normal in power-on situations.

Capacitor surge voltage is standardized in IEC/EN 60384-1. For aluminum electrolytic capacitors with a rated voltage of up to 315 V, the surge voltage is 1.15 times the rated voltage, and for capacitors with a rated voltage exceeding 315 V, the surge voltage is 1.10 times the rated voltage.

The surge voltage is the maximum voltage which may be applied to the capacitor for short periods of time, i.e. up to 5 times for 1 minute each per hour. Surge voltage testing is conducted according to IEC 60384-4.

So as long as the capacitors are good quality and have a proper surge rating they will be fine. Which is why there are 1000's of Mesa amps out there without issues.

All manufacturers build to a price, and that all do that in their own way, it's easy to pick on them when you don't have to answer to the financial burdens of running a company in the 21st century. That aside some do some questionable shit sometimes.

, more that assembly line stuff is now getting into boutique price range.

Maybe I just like hearing people grizzle.

Just wait for the tariffs to hit USA amp manufacturing

Seems like a good time for a forum resurgence in amp tinkering

Bean Counters vs the Engineers, who always wins ?

But it won't hit made in USA amps, will it?

What if Mr orange decides to put 20% on Canadian stuff? Think Hammond transformers...
There are other examples

Well quite possibly, but that's not a USA made item. But if MESA got their xformers wound by Hammond then it could increase the prices. I wonder what MESA (say) gets from Choina?

You think USA made amps only have USA made parts in it?

No - it's a good point!
