Frank,
A buddy of mine owns a music store and started importing KLD amps, which are made in chine. He got these to compete with the mail order/no overhead competition. With a lot of attitude and an obvious smirk on my face, I checked them out. Typical PC build with tube sockets soldered to the boards - just like 99% of all the other BIG manufacturers do. Interesting to note, they had EH tubes in it. They also used Celestion speakers. Did not see any schemo's so I don't know how faithfully the original circuits were followed. Played several versions of Marshall, Vox, and Tweed. I was very surprised - and believe me, I needed to be impressed. Would you tour with them? Probably not, as the build was not what I would consider road worthy. However, it fills a nitch. The price was right for someone wanting the above listed "tones" at a reasonable price to play in the basement or bedroom. AND it's an honest to goodness tube amp. He also said he has never had a return - for failure or repair. He figures that when the owners get a little more disposable income, they will be back for the Big Names, vintage, or boutique!
Heck, I don't know anymore. Cars are sourced with worldwide components. Marshall is sourcing its POPULATED boards from chine (and I'm sure many others are too). All the electronics that everyone uses are made in chine. The line is certainly blurred. I would check out the t20 and see what it sounds like. You might be pleasantly surprised. If you do, post a review!
