@rbertalotto What you are missing, and what’s going on here, has mostly to do with your ability to read.
Best preamp on earth — Where’d you get that? - Hissing, noisy remote control — Where’d you get that? Doesn’t know how to use XLR connectors — Where’d you get that? Bad solder joints— Where'd you get that? Bad paint— Where’d you get that? A loose tube socket — disappointing but hardly the first time an audio product has a missed defect that needed follow up in the field or back in the factory (do you ever read reviews?). Having a tech in the States to help solve problems, vs. having to return the goods to Australia — What’s your beef with that?
What led to an aspect of a (special order) Grange getting a little mixed up re rhe case is not clear, but in the context of a one man operation dealing with lots of requests, orders and building, including the rigors of point to point wiring, plus dealing with his hon audio own everyday life — e,g., take a look at where Mick lives — it’s hardly surprising that mistakes are sometimes made.
