I got a hold of some Wima polypropylene caps. I'm looking forward to the day all of this expenses are done. total build cost for this amp is about $2200.

Why? I'd also regard a mica cap as appropriate, at least as far as it fits into the PCB.
Best regards!

A little late to the game, but finally bought a couple boards. I have sourced the MT-200 Sankens and am curious which drivers are recommended for those outputs? I'm putting together my Mouser order!

Audio driver transistors 2SC4793 / 2SA1837 are liked but hard to find (digikey US has them). There are also Sanken 2SC4382 / 2SA1668 but I've not used them. MJE15032 / MJE15033 are also good and available. Personally, I find it unlikely that a difference could be detected with human ears. The Honey badger is a very flexible design and will work with many different combinations.

I've started installing resistors and found a difference between the v2.2 schematic and the v2.4 schematic. R26 is shown as 100r on v2.2 and it is shown as 10r on version 2.4. I wouldn't be asking but R27 is shown as 68r on v2.2 and 82r on v2.4. Also R23 is shown as 33r on v2.2 and 47r on v2.4. Which is correct, or are they both right, if so what is the change doing so I can make a decision on which way to go.
