I still have and really like my Baby Blue II. I think it has a very cool clean sound. Even though I'm more of a raw rocker or old school clean sound guy at heart, I was instantly attracted to the "classy" clean tone of this amp the first time I heard it, as was my wife who said, "Buy it" when we were shopping for a practice amp for me and I tried this one out (among about a half dozen or so others) even though it was beyond my practice amp budget. Had a lot of fun with it over the years, too.
The preamp tube gives a hint of rubbery compression and sparkle, but overall doesn't do much at all in the way of drive, at least with my basses (all passive, low output, played with not too heavy a hand). The tube probably mainly just makes it run hot, lol, but anyways, the overall sound and feel playing through it is quite attractive, imo. Regarding weight, it's heavy in a way (wouldn't want to walk too far with it), but it's certainly something you can pick up and move around.
It's a bit of a strange size as it's a little bigger/heavier and can get louder than needed for a home practice amp or certainly an apartment or duplex amp, but it's a little smaller than needed for playing with drums, unless the drummer is quite restrained. Still, it can be good for playing in volume limited situations like a coffee shop, or a jam with friends at home where you can be a little loud but the neighbors would complain if people really turned up, etc., a house party, a small room, playing with a non-full drum kit, etc.
I mean, it's not quiet or anything — it's just that it's in that inbetween zone, where it's loud enough to actually play with… but not quite.
Mine's developed a quiet but audible buzz out of the tweeter when playing the low E. Sucks, but I still like it for playing at home. Still dig the tone after all these years.
As to would I buy the one the OP is looking at? Maybe. I'd be tempted. But… yeah, as others have said, you're looking at buying someone else's problem that then becomes your problem. If it's so easy to fix, why doesn't he fix it? And the parts are becoming less and less available, the proprietary speakers no longer made. In some ways, if one really wanted a Baby Blue II, the best thing would be to buy two of them, at least one being in excellent working condition to start with, so as to have on hand everything needed be able to have one amp cobbled together at any given time…
There's other amps out there, so even though this one's not too expensive and the Baby Blue II is (was), at least imo, a pretty special little amp (tastes vary though, so clearly this isn't a universal opinion as can be seen in this thread), I wouldn't spend money on it unless you're handy (you say you arent') and/or have a good relationship with a good amp tech (you seem to not). Could easily end up being a $275 lamp stand that you end up having around taking up space in your room and your head for years until one day you finally throw it out, or end up having to meet some Craigslist sketcho to give it away to. I mean, it doesn't work, and there's no schematics, no replacement parts easily available…
Unless you want a project (you'd be buying a project) and the Baby Blue II among amps particularly attracts you as a possible end result (100% success not guaranteed), with some regret, I vote "pass" too
