Given today's production methods, it really doesn't matter.
The Deville's and Deluxe's use pcb boards as does most middle of the road stuff.
Geez, $4 k Gretche's are being built in China I can remember when "Made in Japan" was as no go zone.
If the materials are good, it doesn't really matter who builds the thing, most of the production these days is computer controlled.
a guy i know spends way too much money on amps and loves his AC30; it's a late-90s one if that helps
prefers his matchless etc but does like his vox. i heard it, it was a cool amp
