Xavier,

Jamb nuts!  I hadn't thought of that!  I have my gold RCA jacks on my equipment backing off all the time.  I need to get a set of nuts and double nut them.

By the way, beautiful, careful work there.

Grainger,

These are the Neutrik rca jacks that BH uses in the tube repro and now in the BP. They require larger holes than regular rca jacks but are now and, as you suggest, stay in place forever.

Xavier,

You'll need to remove the jack hot wire to add a nut and then resolder. May I suggest that a couple of drops of Epoxy on the RCA jack nuts and top plate will securely keep the nuts from backing off.  Loctite and CA won't work as they can form an isolation barrier between the jack and the ground solder lug.  (Don't ask how I know this .....)

Thanks buddie.

Incredible how productive a "labor day" can be!

After maybe 5 or 6 hours only it's starting to smooth. The beast is amazing. My only thought of describing the sound vs the FP3 is a more natural sound. That damn cathode follower does add distortion. Maybe not much and not noticeable clearly until it's out of the circuit. And I guess the linearity of the dht tube is playing a part too. Damn, the best system in the world just got better!

Glad to hear it. There's something very cool about a 300B just loafing. Labor Day in Toluca meant a rehearsal of Mozart's Requiem -- a good day! I just installed the C4S in one of the S.E.X amp kits, which is a nice step forward. I'm a big fan of the stock sound but I now appreciate the increased attention to detail from the C4S.

About 10hrs. The caps are sounding nastier. Not only harsh but muffled as well. Interesting this burn in process!

Hi there Xavier, I assume you didn't end up with any noise coming from the 157M chokes? How's everything sounding? :)

Also, what model Elma switch is that? I haven't seen that one before with the PCB. I usually use the 04-1264 but that one is only 2 poles. Ah, nevermind, I discovered it is a Goldpoint model.
