There are tens of millions of guitar players who lean towards Made In USA quality
A large and seemingly ever growing number acknowledge that tube amplifiers are preferable
Most agree modern production China/Russia/Eastern Europe tubes are inferior to NOS NATO nations 40s/50s/60s tubes
Those NATO tubes are ever dwindling and command huge $$$ despite being out of production and picked over for well over 40 years now
Why isn’t there a manufacturer in the US making design faithful reproductions of those high quality sought after 40s/50s/60s NATO nations tubes ??
