Thanks, so, 604B was introduced the same year as I was. How nice to see it used a series crossover, N-2000, as did the later N-1500A and N-1600A.Originally Posted by mah
My Dad's 604B was wonderful sounding to me back in the day, when it ( and I ) was new !! Series crossover, LMAO !!!! Thanks Marshall, nice link.

Isn't that N-1000?
Your neighbors called. They like your music.
Hi OG,
Not according to mah's link, click on it and see. ( But then, I'm dyslexic !! ) See his URL referenced above please.

Sorry Jeff- read again. It says 604 used the N-2000 but you said the 604b does, it uses the N-1000
604
Network: N-2000-A (also N-2000-B) - series filter networks
604B
Network: N-1000-B crossover - series filter network

Hi OG,
Yes, I was hasty and mistaken on that point. Thanks.
Lotsa ALTEC-designed series crossovers with first order slopes in the early days, when amps were tube type !!
