**Krell KSA50. 50 Watts Class A, 75 Watts Class A/B. Very simple
topology, easy to work on, built-in fan cooling, reliable.
Krell KSA100. 100 Watts Class A. Uncertain about Class A/B power, but
likely in excess of 150 Watts. Similar construction to the KSA50, so the
same comments apply.

If unmolested, both will almost certainly require new electros by now.
The KSA100 was a particularly impressive sounding thing.

Dunno why you want Class A. A decent, high bias Class A/B amp, up to a
couple of Watts will sound just fine.

Ah yes I checked your old posts and saw you have spoken highly of that Krell in the past. Noted.

Why class A? Well, why not?

I have a little second system with JR 149s, right now it's just got a Quad 303/34. I love those speakers! And I feel that with really a really top amp they could be quite fabulous.

But I don't want the trouble of valves . . . so Class A seems a good line of investigation.
