how not to build your bee pre

The 157M chokes fit perfectly!

Thanks Jim. I should have thought to just call Blue Jean's and ask nicely.

Interesting! After the noise in my Eros with the choke under the hood I'm apprehensive of putting them that close to signal wire under chassis. Please keep us posted if you end up with noise.  This is the one mod I'm going to hold off on.

Hi Xavier,

Will you have to do anything to the base to accommodate the 157M's under the chassis plate?  From the photo, I can't tell if the chokes go that far outboard.

thanks!

Hammond chokes in place. They fit and there's no need to modify the base.

BeeQuiet switches also in place.

Hi Xavier,

Awesome - thanks for the follow-up and the picture!

Best,

One output channel wiring. A single 89259 feeds all four outputs. No piggibacking here!

I have to ask, since it is dual mono, has anyone been tempted to put in two IEC connectors so you can use 2 Botthlehead power cords?

I think it might sound better with four runs per channel, you should give it a shot!

(Just joking)

Grainger, not me. I haven't even tried the bh power cords yet.

Paul, look at this other pic showing the output wiring of both channels.

Done with the PITA input and output wiring. Next is the beeQuiet and then the actual preamp power and signal circuits. I'm getting there!

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.

 

[xcortes]

BeeQuiet in place!

looks like the business end of the Hadron!

Home stretch!

Looking good!

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 .....)

Auricap xo output caps, the last non stock item to be installed!

Done!
