Not everything that is made in Germany is good, still I trust them a lot and of course I rather have something build there than in China / Indonesia.
The Ironball looks like this inside:
It's all PCB like everything else that is not a *boutique* amp.
Bugera themselves claims they are *boutique* amp makers and that their amps are handmade (or hand assembled) - it's probably cheaper to pay workers in China then to buy a full assembly line with machines to do all the work).
I might be wrong but I think that Marshall does the other way around - they export the parts from the UK to other countries (ex: DSL100 parts are sent to Vietnam) so that they're assembled there, but the parts themselves are good quality and are shipped from the UK.
