Request to update BOM. I found a better price for the PT-10 box than the link thats on the Excel file.

http://www.pactecenclosures.com/Enclosu ... =Calculate

The case on the original link costs $36.65 (also shown on the Excel file) but if you buy it from the manufacturers site it's only $28.20.

True, but ground shipping is $14 from Pactec, which almost completely erases the savings, as you'd most likely be getting other things sent for the same shipping amount from Mouser (or wherever).

Ah, good point. Ignore that post.

Sorry if this was mentioned already, but I noticed the BOM says you need 94 10K resistors, but on the manual, it says you need 54. http://www.ladyada.net/make/x0xb0x/fab/parts.html

Is either one incorrect?

I think the extra 40 are for the LEDs

In the parts list on adafruit, you need 54 10K resistors and 40 appropriately-valued resistors for the LEDs. I use 10K resistors for the LEDs, so 54+40=94.

The BOM calls out 2x 8pin dip sockets - optionally. However I think you could use up to 3:

2 x AN6562
1 x 25c33

Which is to say I'm almost done and I used the 2 I ordered on the 6562s which go in first.

It's included in the BOM on line 16 for the EEPROM. It's a part that was already specified by ladyada. The 2 optional ones are for the AN6562's.

Polyester Caps

by synthasonic on Fri Oct 15, 2010 9:04 pm

Hmmm... I bought a WillZYX express kit, thinking I'd be all set b/c I have a lot of parts sitting around, only to discover that Mouser and Digikey no longer carry polyester caps. Jameco's site is currently down, so I can't check there. Small Bear has a few, but not all of the values needed for a x0xb0x. Can anyone recommend another source for these caps?

Thanks!

Hi Phono,

I see what I missed before. I had just checked out the parts on the BOM and upon seeing that they were no longer available, moved on to other vendors. So, basically, as long as I match the capacitance value, tolerance, and voltage rating, any polyester film cap is cool, right? For example:

Thanks for the advice!

Is this BOM same as the original tb-303 or are there compromises made? I understand it is possible to get very near the original 303 with the right components so just wanto be sure before starting to order...

The only real "compromise" is the BA6110 in place of the BA662A. The difference in sound, if any, is still a subject of debate. I think some of the kits out for sale use a LOT more 1% metal film resistors than the original, and in my opinion that will make a noticeable difference. As the posts previous to this had trouble finding polyester caps, I think Mouser and others have more of what people will want listed as "mylar" caps, which are the same thing really. Mylar is just one brand name for polyester, and most of them listed as mylar caps will be packaged more like the originals, i.e., dipped in plastic as opposed to being contained in a small plastic box.

Thanks for the detailed answer. Is the BA662A changed to BA6110 because its hard to get or some other reason? And this BOM seems to have all its resistors 1%... But isn´t it just a matter of luck what the final value of the 1% or 5% resistors are, just that they are inside the procentage....

BA662A was made by Roland, thus it's impossible to get unless you salvage a Roland synth. Sometimes they pop up on eBay.
