@andy2 holco has uploaded the schematic. The 14 and 28 uf caps are in the feed. Note the SE version gets full values in single caps whereas the original added 1uf bypasses (ie, 13+1=14). The 43 is a subfeed. Those big ELs are in the shunt position, so they probably make less audible difference but might still offer a sonic improvement with an upgrade. Even if not, it’s worth replacing older ELs.
The decision to go with CSAs is partly a choice of price. I mean, does it make sense to put $8000 worth of Dueland caps in a speaker that retailed for $4000? Mundorfs and many others were considered. Tom and I spent many weeks researching and we each spoke with several people with good knowledge before landing on the CSAs. I was pushing for the top of the Clarity line CMRs but Tom got some good info that the CSAs, possibly with small Multicap bypasses, would hit the sweet spot and for much less money. Toms decisions are very well considered and one of the considerations was price. At the end of the day, Tom wants to not stray too far from the Thiel tenet of value while still providing a very worthwhile upgrade. Might you eke out even better performance with Dueland and such? Maybe! Let us know whatever you try.
