Can someone suggest a good stereo receiver? My nearly 30 year old technique finally bit the dust.
Like, remember, I work in a brewery so kinda budget conscious...

I was looking at this one

If it has the features you need, it should be a good one. In the world of consumer audio, you'll get all kinds of esoteric replies. But coming from a pro audio standpoint, it's a good brand and the specs are listed in real world figures. Price is good, too.

So, my speakers say they are 200 W input. This one is 50 W per channel. Should I be looking for higher wattage? I don't really want new speakers.

It's only a. 2 channel receiver so 100 w total so your speakers should be fine as you are only at ~50% of their capacity:)

Yeah, but I want to use 100% of their capacity! :D

Ideally you want to use only about 70% of a speakers capacity and no more or distortion becomes an issue beyond that

more important than the wattage is the impedance (ohms), ideally this should match both output of the receiver and the input of the speakers or you could overstress the receiver or the speakers depending on which is higher/lower. Not matching impedance has different problems, like excessive power usage, noise, interference and distortion.
The wattage of the speakers is usually the max sustained power before they blow up or become damaged. Any wattage less than that will drive them, but based on the impedance difference, it may require more power to deliver the same amount of amplification.
tl;dr: match the ohms.
