In the 4 to 6 watt range it's hard to beat a silverface champ. Same circuit as the Blackface. Just less attractive in every way (switching, color, etc.) I had a short that fried quite a few things in mine last year. Paid $250 for an almost full rebuild. Should be good for another 40 years
If I wasn't concerned with spending money, not that they are all expensive, for home use I would look at some of the great half to one-and-a-half watt all tube handwired amps. There are times when I would like to turn the champ up and let it run, but it's too much volume. A half watter that starts to distort around 5 or 6 would be perfect.
