B&K ST-140 amplifier buying decision

I have heard good things about this old amplifier. I like lush sound and read this amp fits the bill. Is it that good? Is it worth to pay $300 for it?

I have read there are two versions of this amp. I believe the one I put links below is the first/“better” version. Can someone confirm?

I don’t see any serial or tag on the back but it is old, so it is fine. I doubt it is something else inside :)

It is in working condition but probably would need to be recapped soon. So, that’s another cost. I do want to try this type old amps but then I am not that handy when it comes to fixing this type of stuff. Can do some fixing but not enough.

I had an original ST-140 in the 1980's, and now own an Eagle 2A. The two amps have different sonic signatures, the B & K the slightly diffused/soft "mosfet-mist" character, the Eagle more focused and transparent, with particularly good bass reproduction.

Iverson disappeared off the face of the Earth one day, never to be seen again. Legend had it he was working on something that drew the attention of the FBI and CIA!

I owned the first version and it was a nice little amp; very much enjoyed it. At the time had hybrid Apogee Centaur speakers with a ModWright SWL 9.0 SE with all Clear Days cables… Kimber power cords except on the amp. Was a very nice modest system. Mine was pristine and gave it to a cousin. I bought it used I recall for $120 but that was probably 7+ years ago. I moved to an ARC 100.2 which was a far superior amp but it should be for an amp used is around $1700. I’d shoot for $200 and see if you can cap it at $250. Very clean simple amp and I’d be surprised if the caps need replaced… I bet they’re fine even for it’s age.

I own one, purchased new in 1985. Had the toroid tranny. Owned it for 25 years. Sold it here on AG for $225 10years ago.

I also have owned several Eagle 2 models. I still own a 2C prime (the last one ever made - says so right on the serial #plate). Much better amp, especially if you get the Eagle 2c prime, or Eagle 4 versions. They will likely need recapping too, and will cost more than the st140. There are some Eagle 2’s listed on eBay that are very overpriced (and not selling).
