Recommend a used vintage receiver for under $100?

The Dayton listed above is shockingly good.

"Vintage for less than $100"... I see the likelihood of frustration and disappointment with what that budget is going to get you. The "first" repair will probably cost more than the receiver/integrated alone.

I like what Onhwy61 suggested but if she has to have vintage, and that's pretty cool, then good luck.

I gave my grandson one of those Dayton amps listed above. For the money it is a very nice little amp. If you don't need a lot of inputs or features it might be the way to go.
