I've had a bunch of vintage Altec gear. Got rid of all of it. It's like an old car, too much work to get them up and running and too narrow an application to be worth it, IMO.
I'll catch a ration of shit for this, but it's my opinion.
Not sure what you mean by a "JoeMeek type of bass and drum sound", but I use a JoeMeek VC1Q that I like. It's about 5 years old or something, but it works for me.
