Dude,

Absolutely fantabulastic review. I love your attention to detail. I highly endorse using the Zen 50,75,100, or 200 mf film caps as a cathode bypass if and only if you can't use battery bias or get away with just a resistor. They are superior to the BG's in every way. I am happy you are satisfied with them in your system.

I didn't know caps in the heater supply would make such a difference. Probably because I haven't used dc heaters in a while. I will definitely look into this when I current regulate my heaters for some preamp/headphone amp designs I have in the future. Perhaps you should look into current regulating as well for your driver stage. For your 300B output stage there is a special choke filtered current regulating design type you can find by searching for Tom Ronan's regulators on the bottlehead forum.

I only wished North Creek would make high voltage (ie 600V) caps larger than 1mf so I could use them in parafeed and in the power supply.

I look forward to your review with the Borealis loudspeaker.
