Just to announce that I am running out of the WIMA MKP 4 caps. I plan to ship the kits with the Audiophiler MKP Kondensotor (yes, the name is terrible) red axial caps. Axial works better with the PCB. The Audiophiler are rated about the same (actually, slightly better) as the WIMA in the Humble Homemade HiFi ratings . Trying to keep the cost of the kits low. The TX2575 are the difficult parts to obtain, and I think they are worth the extra cost.
