I had a word with the UK importer at a small show over the weekend. He has tried the 150's in his amp and was'nt impressed. Good for a guitar amp, was his response, too rich, too much midrange bloom.
He said the 150's would be ok in the Ref 75, which I have. He thought the Ref 150 would'nt be ok. There would'nt be a high enough plate voltage to drive more tubes than the 4 in the ref 75. Just what he said, I have'nt heard the KT150's myself. I too would welcome feedback from ARC, I could'nt find an E-mail address to contact them, on the website.
