He said a "Modular clone". He didn't necessarily say a Moog 904A filter module clone. Nuance.
BTW FYI voltor07, in the original Moog Taurus there is a CA3080 performance operational transconductance amplifier in the output section of the ladder filter.
And there are more than a few, 40 years old ICs on the oscillator board in my Minimoog D but it sounds sweeeet.

@xombiexplox,
You've caught the disease pretty darn fast here. Keep up the good work before someone steps in and pulls an intervention.

First, he DID say Moog Ladder Filter clone. There may have been IC's in the Taurus filter, but they weren't used in the filter itself, just on the output. Of course there were IC's in the earlier Moogs, but not in the extent shown by muna93.thealien666 wrote: He said a "Modular clone". He didn't necessarily say a Moog 904A filter module clone. Nuance.

Re: Post your latest purchase!!
You did notice the 6 hand matched, glued together transistors in the middle of his ladder, didn't you ? What he will end up with, will be a cloned design of many Moog filters from the Norlin era: CA3046 at top and bottom, hand matched (sometimes not even that) transistors in the middle steps, and op amp buffers.Voltor07 wrote:...Of course there were IC's in the earlier Moogs, but not in the extent shown by muna93.
It certainly won't behave like a 904A, nor a Minimoog D filter, but it will be part of his Modular synth system and should sound great. Maybe his choice of the word "clone" was not exactly appropriate in this particular case...

Ah, yes...indeed! Thanks for clearing that up. So it's a Norlin Moog filter clone!

Yes I have! I do believe the Minitaur is the last one on the list for a whillleeeeee, I'm just glad I found a site with them in stock! :3 gonna be here Tuesday!slabwax wrote:@xombiexplox,

" I do believe the Minitaur is the last one on the list for a whillleeeeee," Famous last words We've heard all before. Hell, we've said it all before. Enjoy your Minitaur. I received mine on Monday and I'm loving it.

Why stop now? You only need a Voyager and a few 'foogers to complete your collection.

Ohmygosh I wish! If I were to get one of those, it'd have to be sooner than I'd have enough cash for, I am moving overseas for a few years and I don't imagine getting one shipped would be pleasantnamahshaman wrote:xombiexplox wrote:Yes I have!
