Jim, Spencer, thanks for the updates. What a pleasure it is to hear another's excellent system. I am sure it was a blast. Salmon is the king of fish—I love it hot smoked.
Ah, I see. Makes sense. I've a 25R with some DIY mods - 4 x bulk foil input resistors in the input circuit, and main HT electrolytic cap replaced with a Clarity Cap. Big upgrade. I also use these tubes in first 3 tubes -not in regulator. In your case with the 12BH7A, you'd only need a pair. Look at replacing the buffer tube with an ECC99. They take about 20 hours to open up but I find them exceptional. http://psvanetube.com/wordpress/store/products/shuguang-custom-12ax7-lx-special-edition-pair-low-noise-triple-mica/
