Here is the BOM for the 6-channel MOTM-750 Interpolating Scanner: http://www.synthtech.com/misc/m750.txt Just a DOS text file (opens in Notepad/Wordpad, etc). Even though this is a 3U wide module (if you don't know what it is, look at JH's pages on oldcrows.net), http://www.oldcrows.net/~jhaible/tonline_stuff/jh_ipscan.html this module has: 99 resistors 12 jacks 6 LEDs (yellow this time) 16 discrete transistors 8 matched pairs 25 caps 11 (!!) panel pots and 1 switch (not really 2 as the BOM says) 12 dual op amps 15 diodes or about *230* individual parts. Now, the though of soldering this beast I'm sure has several folks drooling already. However, on my end, assuming I sell 50 kits (about average for a new model), that's about *12,000* total parts to be bought, counted bagged and shipped. There is 1 thing I can to to GREATLY speed up the process (and reduce errors!), and that it to sequence all the axial parts (resistors, most caps, diodes) on tape. This is done by machine by an outside contractor. The downside: it's more expensive, roughly 12 cents/part. So, that's 99+20+15 = 134 or $16 labor (plus cost of the parts, not much maybe $8). The other thing is that I have a 100 "set minimum", or I have to run 100 sets. That's $1900 for labor + parts. So, I don't mind doing this, but here is what I'm thinking: asking for a $50 'deposit' via PayPal or money order. This is to offset this cost. The module kit cost is not yet calculated, but it WILL be over $300 but less than $500. So, as a %, the deposit is small. But it does greatly assist my cash flow :) The alternative: 100% SMT, no kits. Paul S.
