can anyone tell me what the three-way switches on the sts-serge mixers are?


Three way switchable phase inversion on that input:



"This has switchable phase inversion on the first channel to aid in feedback experimentation (avoiding cancellation)or you can "subtract" one waveform from another."


sorry if that was confusing. what i meant was: "which brand/model are those switches?"

i'd like to get a few spares. thanks!

Ha! Thought it was a weird question, given the size of your setup hihi

Sorry for the confusion.

Hi

can anyone point me to the right Mouser ref # for a replacement of the frequency pot on the Serge PCO ?

I know they're alpha 50K pots, I guess they are LIN, but I got plenty of results using only these specs with the Mouser search engine, not sure which one to choose seriously, i just don't get it

Thanks in advance

I believe they are these: http://www.mouser.com/ProductDetail/Alpha-Taiwan/RV16AF-10-15R1-B50K/? qs=sGAEpiMZZMtC25l1F4XBU1Dxzr6mc3JG65EyQqJg3Eo%3d

The picture shows spline-type, but these are actually round as you'd use with Davies knobs. These are the ones that I typically use for everything including Serge-ish work.

M-class measurements:
an M-class module is 7.875" wide (height is 7")

The screws that mount the panel to the box are 6-32 x 3/8" pan head Phillips with washer. The panel holes are drilled over-size at 13/64" and are not threaded.

The screws that mount the PC board standoffs to the panel are 4-40 x 9/32" pan head Phillips with washer. The panel holes for these are drilled over-size at 9/64" and are not threaded.

The screws that mount the Obelisk to the panel are 6-32 x 3/8" with a 5/64" Allen head in black. Holes are drilled over-size at 9/64” and are not threaded.

Obelisk, width, etc:

The Obelisk is actually 1 7/32". You will notice that two M-Class modules + Obelisk is ever so slightly narrower than a single full sized panel.

Vsyevolod wrote:
Also, if you're planning on having the Obelisk, minimum depth to your box is 2 1/2".


Good to know for anyone combining M-class with DIY cool

Thanks Stephen!

i'm looking for a replacement case for my beat-up PS4 (not PS4A)..

can anyone confirm that this is what STS uses?

Model# C0-4A

from
http://www.lmbheeger.com/products.asp?catid=16

judging by the measurements (8x7x4) and the color, this should be the one, but it would be good to get a confirmation in case anyone here has ordered one..

thanks!

Confirmed. I used the LMB Heeger C0-4A case for a DIY Power Supply for an older Serge with +6V, and the case matches my STS PS4 power supply cases.

Hey STS Serge modular brothers and sisters, I recently put in an order for banana cables from Testpath, and realized how much time it can take to dig for the right part numbers. I compiled this list based on the standard STS Pomona cable length color scheme to save myself some time in the future, and figured I'd share:

How do you calibrate the PS2A? Do you have to crack the case open?

UPDATE
Rex: "The [PS2A] supplies are sealed at the factory with the outputs preset. The voltage outputs are non-adjustable."

Hi! I have a question on a ca 1979 VCFQ filter that is up for sale where i live. It's in a panel together with a DUSG and a DTG. It's in good order and the price is right but the lowpass output don't output anything. I'm tempted to buy if but am not sure if it's worth the risk? Do you think it would be a costly repair or involve any hard to find parts? Thanks!
