Sansui AU-317 Integrated Amp

I have a chance to acquire a used Sansui AU-317 stereo integrated amplifier (the earliest version, from 1978), rated 50 watts at 8 ohms. The first question I have is, will this work well with my 4-8 ohm Visonik 3-ways (12" woofer) of a similar vintage? The 4-8 ohm rating is rare-- will this amplifier be stable at 4 ohms?

Next, apparently the relay on the on/off switch needs replacing. Will this be hard to source?

Any other tips you have would be most welcome.

Can’t answer your question but as an aside.
I had an AU217 for 25 years, mostly with mission 700s with modified crossovers. A ps cap went pop a couple of years ago. The ps board was the last one to come out so if you end up having to go in that deep do the caps while you’re at it.
