I seem to remember seeing some nice 10 and 15 watt all-tube amps last time I was at the big music store nearest me. I can't quite remember if they were Fender or Vox.. but they had a very vintage "look" to them and were extraordinarily cheap. I couldn't believe how cheap they were really.. I almost bought one right there and then without even testing it out just because it was so cheap and it was an all-tube amp. Would have been less than $100 US dollars easily. I wish I knew the brand so I could point you to them, as I did have a quick play on one of the 10 watt ones using an Ibanez prestige guitar... it had a very nice sound.
