I think you had it right the first time you did it. I've repaired old tube car radios, and have never noticed anything extreme regarding tube mounting arrangements. Some good spring clip retainers for the power output tubes, and then putting the small tubes in shields, would be the way to go. That and use good sockets, don't cheap out and use cheap China sockets which will get loose over time.

Even cooler- Milbert BaM230/235 from the 80's.

I didn't realize they were still active. Milbert, the Most Musical Amplifiers

I had no problem with 1625s push-pull in a 1980 Honda Civic. I used them because they have 12 volt heaters and were selling for $4.50 each from Antique Electronics.
1625s were used in WW2 radio transmitters in fighter planes. I think they will do OK in a car.
I pulled them out after about a year and a half when the car died and the tubes still matched well.

Maybe mounting some bear trap style retainers to grab coinbase octals right where the glass and bakelite/plastic meet?

I think Tubelab has been down this road. Pun intended. I'm sure he would have some insight.

I can tell you what the military did back in the Tube Era (as I was an AT-3 in the NAVY doing intermediate level maintenance in 1973), they shock mounted the equipment, not the tubes.

Isolate your chassis.

Use it's mass to your advantage.

Laws of physics are the same now as then.

Iím unaware of any new sockets NOT manufactured in China, besides maybe Belton which I think is Eastern Europe?

Can you enlighten me?

Belton is Korea, they're pretty good. I'm not an expert by any means, usually I try and find old stock Amphenol or Cinch, if I am building something for myself. I haven't had good luck with the Chinese ceramic sockets
