Different tube amps sound different, so I'd hesitate to have you make a decision about how a tube amp sounds based on one particular budget amp. That said, I'll give you some of my thoughts.
1) For a low-budget amp, I love my Jolida 302b integrated. It has a warm, relaxed sound that glosses over only the smallest details.
2) If you're looking for just an amp (as opposed to an integrated), a Cary V12 would be a solid choice to drive your Electra's.
3) If you want something even more on the warm side, try one of the rebuilt Dynaco ST-70's.
4) For just a hint of warmth, I used to own a pair of Audio Valve ppp45 monoblocks that I miss. They're rare on the used market, but available in your price range when they do come up.
I hope that gets you started.
