The beauty of tube technology is the ability to produce circuits that are easy to repair. Equipment that is point to point wired has the highest potential to make it through the ages regardless of who made it (as long as it was properly made). There are hundreds of Scott and Fisher amps still around and in good condition. I wouldn't worry about the amp's maker disappearing. Be concerned about how the amp is constructed. Construction details are extremely important. A good design that is point to point wired is superior over those made on printed circuits. I've dealt with enough lifted traces and burned boards for a lifetime. Glued wires belong in computers, not tube audio gear.

I agree that point-to-point is more reliable, easier to repair, and easier to modify; not sure if one approach is any better or worse for sound quality. I imagine one advantage to circuit boards would be consisteny from prototype to units on the market and less variance between units due to more precise duplication of circuits from unit to unit. You do make a very valid point (no pun intended) that point-to-point gear eliminates much possible obsolence in repair down the road.

P.S. All my gear non digital electronics is point-to-point.

My Lamm preamp (L2 Reference and LL2 Deluxe) were both circuit boards, as I believe were my VAC amps.

I'm not sure I've read here any instances of Lamm, VAC, ARC, BAT or CJ gear going bad due to their circuit boards.

I have often read about the better reliability of point-to-point wiring, but I'm not certain it's based on real world statistics comparing repair frequency of one method versus the other...especially in the more established brands.

I don't think the problem is that circuit boards tend to go bad (not good ones), but if they do they are not easy (possible) to repair. Of course if you own ARC you are not likely to have to worry about a replacment board. I'm not sure you hear many argue that point-to-point is inherently better sounding - don't know about that on way or the other.

I understand that point to point is easier to repair, and that it's possible for almost any trained tech to do the work.

To me, this would be more of an issue with products manufactured overseas and from small companies without substantial history in the business.
