And 50Hz too, for half the country!

Re: Yamaha releases 01v96i
Thanks. Yep we're 50Hz here too. I seem to recall a service manual for the 01v96 showing a real transformer and nothing frequency sensitive. And in most cases we've found 100v gear can tolerate 110v (with one exception that released it's smoke).
Cross fingers...

Re: Yamaha releases 01v96i
The problem isn't frequency sensitivity in the electronics, it's the transformer being able to deliver enough current at the lower frequency. 50Hz requires a bigger transformer for the same power delivered, perhaps Yamaha designed their PSU with this in mind. As for 100v vs. higher, the 110v may be OK, but you can easily see 120v here.

Good point, thanks. I'd forgotten about this.
