I had a 70s 100W master volume combo in a 2x12 cabinet. It was awful - weighed a ton, and was really loud by the time it sounded interesting, which meant either loud and really clean, or loud and really fuzzy (full Iron Maiden!), with nothing in between.
Now I have a 'valvestate' 100W thing which someone gave me, as apparently no-one likes them. It's great - really flexible, good-when-slightly-crunchy, and good quiet as well as noisy. It came with a Yugoslav ECC83 which I replaced with a Mullard (cos I had some) to predictably no result whatsoever. I ought to sell that valve and buy a few sets of strings
