By the way, I'm selling this synth in the Fleamarket [EDIT: SOLD] Which is why I got a bit nostalgic when I thought about actually parting with it, and I drafted the note above. I may never find out who the mysterious builder / seller is or was, but I'm certainly grateful for the transaction... ;-) Cheers all, -Darrell

Apologies for the suspense, but I struggle to find a few free minutes sometimes... Good news is, they test perfectly under minimal load on a breadboard. Not sure when I’ll have a chance to test one in an actual build though.

Seems like there are no takers here in the forum, so I'd like to try to sell these through another channel if possible. Any concerns with that? Thanks, -Darrell

To add some more context to this topic, I’m sharing the full side-by-side comparison as an Excel doc. The BOM reference is for a complete MB-6582 build, with two sets of sourcing options (one using mostly premium components from Mouser and the other uses more economical alternatives, from the likes of AliExpress, eBay, Amazon and elsewhere). _MB 6582 BOM - Economy vs Premium Build Cost Comparison - Oct 2020.xlsx The short of it is, you can make a complete MB-6582 today for around $513 USD, when you only consider the costs for required BOM components. However your total out of pocket expenses will actually be significantly higher, because you'll need to buy in bulk to get better volume prices (e.g., closer to $1,127 USD). This obviously means that after the build, you’ll have plenty of spares sitting around for your next build or another project. For a premium build, which uses real SIDs (8580 R5s), panels from FPE / Shaeffer and components sourced mostly through Mouser, your BOM will run closer to $1,221 USD. In this case, out of pocket expenses would come in closer to $1,661 USD, which means you'll still have plenty of spare parts left over, but far fewer than with the more economic option above. There are obviously many other sourcing and bulk volume options that can be considered and all of them would have an impact on these numbers, so consider this to be some type of rough guidance. Hope you find it as useful as I did when planning your own build(s)... Cheers, -Darrell

These just came in the mail... Will try to make time to test soon...

Yeah, it requires a bit of extra legwork with each and every purchase to find the best deal. I’m not always willing to price compare for the smaller one-offs, but for larger BOMs in the ~$100+ USD range, the saves you can find are usually worth the extra effort.

I’m guessing that SID playback should work, since that already works well to a MB-6582 or sammichSID using MIDI Patchbay and TK’s ASID mod for SIDPlayer. However, using MIDI encapsulation to manage the ARM2SID config is an altogether different animal... Waiting for a window of free time to give this a try though... Cheers

For the most part, I've been sourcing my components from either Mouser and or Digikey, but lately I've started placing one-off bulk orders with AliExpress. You can typically find what appear to be great prices on larger quantities of discreet component, but then there's always that large shipping fee (at least to the US) and the significant wait time for deliveries (which typically take 4-12 weeks in my experience). So, I decided to take a look at some of the components I need for a particular BOM and compare the actual costs, side-by-side: In each case, I tried to source the cheapest components from reputable suppliers with the most positive reviews and feedback. You'll notice that the volume and quantities aren't exactly the same for all items, since Mouser required some minimum qty. for certain items. But in the end, the cost delta worked out to only be around 9%, so I decided to stick with Mouser for most of this order and benefit from the trusted quality and faster shipping time. Apologies if this is stating the obvious, but the exercise was helpful for me, so I thought it was worth sharing. Cheers, -Darrell

[EDIT: Both have been sold] Selling two sammichSIDs which were built earlier this year (March and May 2020). The silver one has two 6581 R4AR SIDs and the black one has two 8580 R5s. Both are running the latest MIOS 1.9h and firmware 2.044 Both come preloaded with tons of patches and ensembles from the forums and elsewhere. Happy to sell them together as a set or separately. If you already happen to have your own SIDs I can sell them cheaper with empty sockets. I’m based in the US (NYC area), so a domestic buyer would experience the fastest, cheapest and most reliable shipping. PM if interested...

I would suggest trying Julian's shop first: http://thebeast.co.uk/?product_cat=midibox He’s based in the UK and he typically has panel sets ready to ship internationally. And as I said above, his prices are the best I've seen (e.g., £80 vs £170) If you want to source local to Germany (Berlin), you can try Shaeffer: https://www.schaeffer-ag.de/en/front-panel-designer/?lang=en Whichever way you go, good luck with your build and post some pics when you're done.

I was planning to configure them using my Ultimate 64 (https://ultimate64.com/Ultimate-64) I can certainly give the Vice + ASID thing a try (Hmmm... Interesting)

I'm selling my first MB-6582, which has been with me for several years and has never let me down... I just finished building a brand new MB-6582, so it's finally time to pass along the baton to someone else, who wants a pre-built system to play with and learn from. Included are: 8 * SwinSID Nano Chips, which were recently assembled and they sound great IMHO (all configured to use the 8580 filter) 16 * 22nf metal film capacitors, just in case you want to swap in some real 8580s 4 * brand new PICs, flashed with BSL 1.2b, MIOS 1.9h & firmware v2.044 Banksticks are pre-loaded with plenty of patches from TK and the rest of the MIDIBox Community Using JST XH cables and connectors, which enables quick-and-easy removal and maintenance of the Control Surface Comes with a 12VDC 3A Power Supply compatible with 110VAC US power sources (it says it supports 240VAC, but I haven't tested that) Power Supply 5v regulator has been swapped from a linear 7805, which ran VERY HOT, to a nice-and-cool Recom switching regulator (e.g., https://www.mouser.com/ProductDetail/RECOM-Power/R-78B50-15?qs=YWgezujkI1JgY7IeN1uB3w%3D%3D) I’m based in the US (NYC area), so a domestic buyer would experience the fastest, cheapest and most reliable shipping. PM if interested... ** EDIT: This has been sold **

Guess what showed up in the mail today, fresh from the Czech Republic? Sound test soon...
