My dad and I used to built Heathkit stuff when I was a kid. My dad actually built a color television which was a huge project. I ordered a Metropolous kit and my dad hand wired the whole thing beautifully and it was the last thing he built before he passed away so that amp is pretty special to me. Yeah, they are a good company.
Marshall is a legendary company and I must point out they are still family owned as is Peavey. Jim Marshall and Hartley Peavey are the last of the old guard and neither sold out. Both companies have made their fair share of mistakes and have had some bum products but overall they are still the real deal. Look at what has happened to the others who have sold out. Just a brand name usually with a lot of debt attached and marketing people and finance people wanting to maximize profit.
