Got the new couplings caps and load resistors installed...

Posted by jeffreybehr on April 17, 2016 at 01:24:01:
...Wednesday evening and got the amps in the system and the system rebalanced (for their higher gain) last nite. Tonite, even after enjoying a fabulous concert of REAL music played by the excellent Phoenix Symphony Orchestra and with only about 30 hours on the amps and with too-long, lower-quality speaker and IC cables in the left channel, the system sounds GREAT! I'll be running these about 15 hours/day weekdays and 24-per on weekends until they get at least 500 hours on them.
The new coupling caps are very small (0.01uF) SoniCap Platinums driving new PRP load resistors of 390K for a high-pass filter of 42Hz. This will protect the otherwise-filterless MR drivers in my Serenity Super-7s.

I'm THRILLED!
BTW I'm using Tung-Sol 'N7 roundplates in what I believe are Vs 1 and 3. I plan to use A-S's gain-reduction plugs in the V2 positions, and probably I'll select some low-testing TSRPs to use in the cathode-follower (V4) positions. Right now, the four TSRPs were selected for moderate transconductance and low microfonics.
