@tomthiel thanks for the information. Heat management was definitely on your radar when I did my build. You’ll recall an early solution that we abandoned. But it sounds like you continued to work things out. I hope you can share this with the world sooner than later (products or “how to” manuals).
@pieper1973 when I upgraded the sandcasts on my OEM boards (sourced from FST), I bought all Mills in identical values. But when I did the full rebuild, Tom had me parallel 60.4 ohm Mills for the 30 ohm position - more surface area for cooling that big resistor. The downside is it costs twice as much. But there is a sonic benefit to running in parallel, at least for bigger resistors.
