Re: Final audio output ?

Does anyone have any knowledge or info regarding final output ? Both the 902 and CP3 mixer are DC, so one could get a DC offset from the output. The 984 matrix mixer is AC coupled and better suited for output to a console mixer or recorder. DC offset can cause distortion and lower volume/headroom d...

Re: early Modular cabinets actually Walnut ?

I know I have posted a few pics of the old walnut keyboards that look somewhat red in the photos. Probably an artifact of using a flash makes them look red. With a longer exposure in low light they look correct. Most of those 60's units I have used walnut veneer over furniture grade plywood for long...

Re: Moog Modular with MIDI

Wonder if there is not a fault with your Y cable? If wired incorrectly a short to ground could occur, causing infinite sustain. Would look there first and check for proper wiring. Use the same Kenton here with my IP. Fires all three envelopes fine and use both the S-trig and positive gate settings w...

Re: Karn Evil 9 3rd Impression Arpeggiating sound on Minimoo

Sounds like the 960 sequencer playing an arpreggio on the modular to my ears? I believe you can see Keith using the same effect on the same Caljam vid on the Great Gates of Kiev around the 4:40 mark. Not sure how it is triggered, but looks to be a delay and starts after a held note and resets on the...

Re: Screw fixing module mounting rail

There was a discussion a while back in this thread;: m Since that time I did complete several portable cabinets. I made my own mounting strips from aluminum stock. Very similar to those Dotcom 19" rack mount rails. Here are the parts I used to construct my rails using 1/4" square aluminum ...

Re: Moog System 35 from Hell!!!!

Do the symptoms go away when the CV1 buss is disconnected? The lighted switch for the CV1 buss is lit on both 921A controllers and there is no connection from this buss to the large 921. Might be a bad connection to the rear from the multi pin connector that connects CV1 from a keyboard (951) or rib...

Some liked it, while some claimed it removed the subtle vibrato one could get. Never tried it myself?

Re: No pitch-bend spring return on new minimoogs !!

I always thought Moog invented the spring return on the pitch wheel. The first Moog product with this feature I know of was the 1972 introduced Sonic Six. Moog called it the "Floating Touch Pitch Bender". My early Sonic Six with a build date of 1973 has this type bender Can See the mechani...

Re: Super hard attack from 911's ?

You can use a multiple to multiply any signal. Simply patch the output of the 911 into a multiple and patch three patch cords into the three CV inputs on the 904A. Typical Moog amplifying patch. One can normalize the front panel CV inputs on the 901/902/904 by cascading the three CV input jacks with...

Re: Wiring Issue with Moog System II

On the August 1969 revision 905 here the -6V tab connects to nothing. The listed schematic in the Norlin era book is not the same revision as I have here. The transistors on this one is a 2N3392 for Q1 and 2n3391A for the other three Q2-Q4. Usually seeing those old transistor numbers is an indicatio...

Re: Information on CV units in System II?

Looks like a stock circa 1968 system IC. As seen here from the Moog Achive site. The cosmetic difference between those early 1968 systems are the use of Switchcraft Lever-lite switches later replaced by 1969 with UID Ulltra-Glow slide switches. And the S-trigger outputs on the CP4 were 1/4" soc...

Re: Troubleshooting Old 905 Reverb Unit

I would recommend cleaning the stock dual pot before replacing. That schematic for the 905 also claims the unit ships with straps to hold the spring unit from bouncing around. Those black straps should be removed and the reverb tank supported only by the suspension springs. My 1969 Moog also had the...

Re: Greetings Forum and all Users. 907 Bandpass Filter Bank.

I have only seen that one. It was auctioned off on Ebay. Can try contacting the seller as the auction page is still there. m Looks to be an early version of the 907, probably 1964/65. Only those very early modules used the RCA type sockets and a male 3 pin Cinch on the back for power. Eric Siday had...
