Then pick the 470uf's. Sorry, but you really do have to put a bit of effort in this. There are more caps available than we can shake a stick at.

No, the BOM doesn't need to be edited - only understood.
There are three sets of electrolytic caps used in Dsavitsk's PCB. However, the cathode bypass caps are optional. That's why I assumed you were talking about the output caps. In the early renditions of the SSMH, the output caps were the same as the power caps. Fair enough. However, the first choice would be to upgrade the output caps to something of an audio quality. That's where my comments were directed.
It's true that the Muse ES are recommended for the cathode bypass caps, but that's the third priority in the string of requirements and AFAIK, no one has used them on a P2P design. So, please forgive me if I thought you were talking power caps first, then output caps second.
If you are wanting to try the cathode caps, but not purchase an audio-quality cap (Nichicon KZ's are available at Mouser and the cathode cap need only be rated for 16V), then any old 220uf 16V cap will do. However, almost all of these will "sound" better if you use some Wima film caps for bypasses (MKP10). Quote:
Do some more work. Stick with UPW's or UHE's from Mouser. You need at least a 63V rating for the power caps and output caps. It would help if the power caps are at least 680uf's and the output caps should be at least 470uf. There are a lot of options under those requirements.

You won't like this answer, because it requires another source and separate shipping charges, but John's Wire Shop (navshipps) on ebay is an excellent source for SPC teflon-insulated wire (doesn't melt when you solder it). 22ga is the best all-around size, IMHO.

I guess I should consider a different source for caps at least. |

I'm confused now: The Muse ES 220uF 16v is what I read in the modified BOM on diyforum, with link to beezar.com, and note in the spreadsheet about also being available from handmade audio. If that's not the correct one to use, perhaps that BOM should be edited? |

If I can't get the caps from mouser (within reasonable time, at least), I guess I have to split the order up. If anyone has suggestions on where/what to get for the caps, I'd appreciate it. |

Also, any recommendation on the wires? I used cat5e cables on my first build, but found the insulation too easily melted when soldering. |
