Do you guys know the difference between a double and triple-mica Sylvania Gold Brand GB6080? Except for the mica, the internal construction is identical. The triple however has a tan colored plastic bottom while the double is black.

   As i said before my CRACK and S.E.X. was not working,2 weeks ago i managed to fixed the CRACK and today i installed a Cree Diodes.
 

As the proctologist said: glad to see your Crack is healthy again!

Has anyone tried choke loading the cathode of the power tube (6080 etc) of the Crack? I have read about supposed benefits of choke loading a cathode follower.  While I don't have a Crack anymore, I am interested in its effects in respect to another build.

Check out the Bottlehead forums - this topic is discussed rather extensively there in the Crack thread IIRC.

Thanks for that.
 
I know that there has been extensive experimentation with chokes to replace the resistors in the power supply, thus CLCLC or some variation thereof.  I also know that the subject of plate (anode) loading the 12AU7 with a choke has been brought up, but that the experts prefer the C4S.  I haven't seen any mention to date of loading the cathode of the cathode follower with a choke.  Can you please provide me with a link to where you have seen this?
 
Warm regards

Neat idea. Do you have a scope to show the difference between the two bridges? I assume its better. :)

 Sorry i don't have a scope.To my ears with this MOD the background  is quieter(this crack never have any hum before the cree diodes was installed now it's even quieter),overall sound is smoother.
