gerald.wert Posted May 22, 2018 Report Share Posted May 22, 2018 Started putting together the external filter for my sid. I am trying out the ssi2144. I have not seen anyone post about using one on here yet. I have the adapter boards for them. All I have to say is that is some super small soldering! I think I have them in good shape though! I reviewed the schematics and it looks like it should work ok. The ssi 2144 has slightly different recommended caps then the SSM2044. I ordered the recommended caps forom the data sheet for the ssm and the ssi I may test both to see if I hear a difference. Will likely go with the recommended caps from the data sheet. There are a few other minor resistance changes on the data sheets too but not sure if they are required I will have to see how it sounds. The adapter are from https://www.amsynthstore.co.uk/SSI2144_to_SSM2044_Adapter_PCB/p1461448_17854795.aspx modular addict sells them too but had been out of stock. https://syntherjack.net/ssi2144-to-ssm2044-vcf-converter/ also has published an file for them as well but I only needed a few of them... for 1.5 I picked up a few extra incase I broke them. If they all work may build another filter for something else. Did I mention that solder pitch is tiny!!! Here are the caps the ones on the left are for the ssm and the ones on the right are for the ssi. C19-C24 10nF, 6.8NF for SSI2144 6 STYROFLEX 10N C25,C26 820pF, 560pF for SSI2144 2 STYROFLEX 820P Quote Link to comment Share on other sites More sharing options...
