I get the same feeling with my 2007 JVM. It’s a shame when built quality gets squeezed out. Durability is part of having truly nice things.
The JVM feels solid compared to the Origins. They're ridiculously light and flimsy for tube heads.
I tried them out at the local music store a while back. They sound pretty awesome. No idea regarding "build quality", I don't tend to judge amps by picking them up and comparing weight.![]()
You might if you've ever had an amp stop working before an important gig but who am I to judge?
Reliability of an amp is necessary of course. I've had problems before from bad tubes, scratchy pots, blown speaker, capacitors in old amps that were on their last legs, a bad input jack, and a dead fuse. If you have reliability issues related to . . . anything that causes reliability issues in an amp, then that would be a valid point and cause for concern. But you've been saying that the amps are not reliable because they aren't heavy. Personally, I've never had an amp stop working before an important gig because it didn't weigh enough.
With weight I think EP's biggest concern is that the transformers aren't up to the task. I would also be concerned about overly-light PCBs that are prone to flexing.
I've never had an amp with those issues, but I had an old laptop where the GPU literally broke loose from the motherboard due to PCB flexing.
Are these heads cathode biased? Thank you

Had a little test run of the 20W head. It sounded sweet through a Greenback cab. The response reminded me of a Plexi rather than a JCM800. I'd say if you're into the Marshall thing, for the money it is rather hard to find a better and more authentic Marshall sounding amp.
