Your Clarity Cap plan sounds good. You can save money and space by going with the 250 V version for the larger capacitance value (ie, 10 and 18 uF) and 630 V version for the smaller value (3.9 and 10). Another path to 28 uF is to get 25 + 3. Madisound has the CSA 250 in 25 uF and I think Partsconnexion has the 630 V version of 3 uF. You might also get add a small bypass to each, say 0.1 uF. I’m going to try Multicap RTX at ~1% but Cornell-Dubilier is a worthy contender, among others.
You might also upgrade the 43 uF cap which is a subfeed. That cap is downstream from the 16 ohm resistor so you can go with a lower voltage. Until I started working with Tom Thiel, I considered a 39 uF ERSE Pulse X (100 V?) + 3.9 uF CSA250V. Finally, those 100 uF electrolytics should optimally be replaced with MPT-type capacitors. Again, ERSE PulseX is a worthy contender but you might have trouble fitting those on your boards. At the least, I suggest replacing the electrolytics with fresh ones (see Tom Thiel’s recent post on the Thiel Owner’s thread).
While you’re in there, I highly recommend replacing all resistors with Mills (or Vishay-Mills) MRA-12s. Sonic Craft has all the CS2.4 values although you have to mix and match the old (Mills) and new (Vishay-Mills). Only about $100 for all and makes a worthwhile improvement in SQ.
