Thanks B/Funk!

Edison I Pmed you.



About the resistors 1k PT146 (3500) , I found them here >

http://www.precisionresistor.com/ordera.asp

But the minium order is for 25 USD, so I must buy 9 or more, and I only need 2.

Is anyone interested in? I can buy it and after I can send tou you , of course, for the same price + shipment from Barcelona Spain. Paypal.

Anyone?

[huck]

hey is there going to be another run of these ?
i need more for another project

Hey I finally got mine built. Great great sounds. Compact power! And I've got another SSM2044 chip free for later use..

There were a couple of little mods I did which maybe have/have-not been mentioned before.

-- Inverting or non-inverting -- I chose to go for the inverting input due to the inverting buffer afterwards. Popped up a resistor and flew a wire across. I'm not sure what other people would think on this subject??

-- the other thing was the Freq pot -- I just noticed the comments above from Mathias - yeah, I found that I couldn't get a decent range originally (though I did wonder whether my 12v supply was the issue) so I cut the Freq pot's trace to ground and jumped in another 47k resistor down to v-. This definitely seems to have made things better.

Aceness! I want to do a souped up version for the 2nd SSM chip.

i just ammended the documentation to reflect the latest enhancement (R23 now 75 for wider CV2 range). for the cutoff freq potentiometer i recommend the alternate wiring as shown on the schematic.

Hi,

I'd like to place an order for 4 boards if they are still available

[fonik]

[fonik]

SOLD OUT

thanks everyone.

[Luka]

just got mine in the mail
thanks matthias

if anyone has a spare ssm2044 drop me a PM
i would rather buy from you lots instead of heading to ebay so let me know
(only after 1 chip)

[Junk Rhythm]

Any chance of another run on these PCBS? I'm sitting on a few ICs that need a new modular home.

[fonik]

actually not. however, it is a low part count circuit, you could easily build it on perf board, i believe.

[Junk Rhythm]

Perf board it may have to be.

[toppobrillo]

etch it!!!

I have an SSM2044 vcf pcb layed out. I am willing to do a run of this if enough interest is generated.

Here's a picture of it:


It has (2) overdriven Audio inputs, an Fm bi polar input and regular CV input.

I 've made a quick search for ssm2044 and it seems that the only place where i can find it it's ebay. The price it's around ten euros

[fonik]

[TekniK]

utsource have plenty of them and am sure they r cheap

note the haxter board is for 2x 2044,i guess its a stereo filter.

If someone has ssm2040 for sale plz PM me.


Fonik,if u made another run am interested into 6-8 boards or something

[EdisonRex]

I still have quite a few 2044s in my collection, along with 6 boards in mostly complete condition. PM me, I am more interested in a trade than a sale, but will sell too.

[scriptstyle]

just finished one of these.(the self etch pcb) nice quick project, and a quality filter. thanks fonik

[haxster]

note the haxter board is for 2x 2044,i guess its a stereo filter....

No, it is actually just one chip(MONO), I just silkscreened twice because once the chip is stuffed you can't see what chip is what on the pcb.

This has an Onboard PWR supply also (optional)

The IC's are:

SSM2044
TL074
(2)TL072

[fonik]

i think this thread should now be moved into the fonik's place, just for completeness. janitors?
