Would anyone recomend a first time owner Valve amp?
You need to decide exactly what kind you like first, and what type of load you're driving.
I'm not a "single ended triode" fanatic at all, although I have heard one or two setups that sound great. An amp like this won't be at all tolerant of a modern speaker so you'll spend the rest of your days trying to find a speaker that'll be happy with it, and sensitive enough.
A reasonable push-pull pentode amp will drive most modern loads, develop enough output that you won't need super-sensitive speakers (although yours are from an era when sensitivity mattered, so are probably OK) and is probably a better starting point.
The problem with buying amps off the shelf is that most of the cost will be in the mains transformer and output transformers. If these have been skimped on and are not up to the job it's not straightforward or cheap to rectify the problem. Valve amps aren't too hard to build and that may be an option. Better in some ways to buy the best set of transformers you can afford and build the rest of the amp with cheap bits - then you have an upgrade path.
Other options might be to buy some old classic amps like a pair of Quad IIs. They are getting collectable now, unfortunately, so are often silly money but if you can pick up a pair in need of some work at least you know the iron is capable of good sound.
It's a shame because there used to be a lot of good kits around but they seem to be a little few and far between these days. Some nice ones here but a bit pricey!
