Sine Square Saw

Hey funkminsta, it'd be roughly $30AUD without tracking and roughly $65 with tracking. Approx.

Hey all, I have one of my two sammichSIDs up for sale. It's complete and comes with an Australian plugpack. I'm downsizing my setup and getting rid of a few things that are excessive. It's got green LEDs and 2x 6582a SIDs (I think, will double check). It has only been used in my home studio and has not been gigged or around smoke etc. Am looking for $250AUD for the lot. Get in touch here if you're interested. Will try and post a photo or two when I get home.

nah everything works a treat. Put the SIDs in and gave it a burl. All good. Thanks again for designing such a nice piece of kit. I definitely owe ya a beer.

Picked up a new multimeter today. Everything is in fact hunky-dory. Did the voltage tests again with the regulated supply and everything was as it should be. Crazy. I wouldn't have expected that. Thanks for all your help Wilba. I'll install the SIDs and see how it goes. Benji

Tested the 12v regulated PSU, multimeter measures it as 11.12v. Replaced the battery in the multimeter, no change in measurements. Measured the power again this time using the 12AC PSU that you sent with the kit and got the following measurements: J20 should be 9v I get 8.19v J2 should be 5v I get 4.61v J1 should be 12v I get 13.23v On the voltage regulator 7809(9v) where I should get 12v I get 16.35v On the voltage regulator 7809(9v) where I should get 9v I get 8.19v Definitely booted, loaded firmware and transferred all the patches OK. Maybe my trusty multimeter isn't so trusty. Could I have cooked the voltage regulator? Cheers mate, Benji

Hey all, just completed my sammichSID, really nice straigtforward design. Many thanks to Wilba. Got as far as loading the patches on and the firmware, but just went through the final voltage check before installing the SIDs and discovered a few oddities. The voltage between pin 28 (top-right corner) and pin 14 (bottom-left corner) of each SID's IC socket is not what it should be. I'm using 6582A SIDs and the voltage there should be 9V, instead I'm getting around 5V (4.16v to be exact). I've tried it with both the 12v AC powersupply that Wilba sent me and a 12v DC regulated supply which I had already and I get the same voltages. J20 should be 9v I get 8.16v J2 should be 5v I get 4.16v J1 should be 12v I get 11.11 On the voltage regulator 7809(9v) where I should get 12v I get 9.76v On the voltage regulator 7809(9v) where I should get 9v I get 8.16v I've double and triple checked everything in the guide. I was also very careful to solder everything quickly and there don't seem to be any dry solder joints, but who knows I may have botched something. Has anyone else experienced this or have an idea as to what I may have done wrong? Thanks all, glad to be starting in this wonderful world of SID synths. Benji
