I was in the same boat recently, honestly I just like the look of vintage gear and wanted one for my bedroom system. I took a look at the specs for your speaker. You can get what I got, a serviced/recapped Kenwood KA 5700 Integrated Amplifier.
Stunning audio quality. Last two days it was powering my bedroom system and sounded great, but I have tiny full range speakers which aren't suitable for all types of music. So tonight I hooked it up to my main rig, and at least on low volume it sounded stunning. Absolutely wide stereo separation, distortion free crystal clear imaging. The VU meters barely moved...I mean it was very late so I listened at a low volume, but it sounded great. I did test to see if the volume picks up, and it does, my speakers are very efficient so it had no trouble. I just couldn't test it for long because I do have neighbors.
It was around $250 shipped.
For reference, this is the unit I bought:
