So I can't win. My ebay order fell through for some Russian K40Y-9, and my current vendor for parts (Allied.ca)doesn't have the Nichicon caps suggested for the B+ on the K12.

As for the C2/C3/C6/C7 I'm on the hunt for something I can get that won't arrive sometime in March. It's a mixed bag but the consensus was go Russian. I have had the kit for 2 weeks in a box and don't feel like another 4 week wait. Any recommendations would be appreciated.

Judging by what I've found in reading the B+ caps should be of low ESR such as the Voltsecond recommendation of UVR2E331MRD which I'd have to pay $20 shipping to get from digikey, unless somebody of greater knowledge than I have about caps can suggest a cap from allied.ca.

Reason for sticking with allied is they have the rest of the parts I'm looking for, my list is below for critics or cross reference to digikey.ca to keep the order to one site. OPT's are on the list but just not right now incase anybody was wondering.

Well I need to get some XO parts for a speaker project from Solen so I can just place an order for some PPE022 0.22uf 630v Metalized Polypropylene caps from them for the coupling capacitors.

Now I just need to figure out what to do about the B+. I just want to keep my order to 1 site to save shipping costs. Guess I can spend some time on digikey.ca for my main parts that way I can get the Nichicon caps for the B+ as recommended.
