TU-8600S

Phew.  I bought the last one!

I built the 8600R and use it in my small system sourced from a BluOs Node and driving a pair of Harbeth P3ESRs.  Rather nice sound.

I had tried the 8600R in my big rig between the K-01xs and the Atria IIs (?Reference System - ugh) and though it excellent.  I was surfing around and saw that there was a TU-8600S with the Lundahl OPTs for sale - I was drinking a glass of Patricia Green Cellars Pinot Noir - which may have something to do with the spur of the moment purchase - so I went into my office and ordered it.  The kit should arrive later today.

It will be a few days before I can start building it as my wife is in the final stages of her MoMA holiday card submission for 2026 and I do all of her Adobe Illustrator work.

Any thoughts on upgraded caps, the Mundorfs or Jupiter beeswax seem to get good reviews but possible a bit of extra top end from the Mundorfs (and with my tinnitus I do NOT need that)?

What an interesting little amp project. On a scale of 1-10, how difficult would you think this build would be? Assuming 1 is a complete novice who has never touched a soldering iron, and 10 is a proficient DIY builder who can handle most anything out there. 

The variance in resistor capacitance does not seem promising though. Did you ask the seller about that?
