I don't see too much about the Vincent SV-237 hybrid integrated on the web in general. What do you Vincent owners think of the SV-237? I'm considering the SV-237 but I've read conflicting thoughts on Vincent. Some say it's made in China and re-badged. Some say it's made in Germany? I've also read that at least one of the three tubes is soldered in? Can anyone shed some light on if the tubes are easily rolled and not soldered in on the SV-237? Soldering is a deal breaker for me, unfortunately. Can anyone give me their thoughts, and any info on tube(s) being soldered in, and or re-badging, and also what they think of the SV-237? Thanks.
