Elrog 300B vs Takatsuki 300B tubes

Hi Bill,
I'm very glad that you are doing so well and indulging in your  hiking passion 😊
No  I didn't get your reply email, I am very interested in your in your thoughts on the two speakers. Bill the SR fuses are something quite special. The many positive comments about them are legit. If you only want to try just one,  put it in the CSL. The Red is excellent but the Black is a step above. They're terrific tweaks for the CSL.
Charles, 

Bill,
With the kind of hiking schedule you're following you must really be whipping yourself into seriously good physical fitness. 
Keep it up! 

Charles, I resent my reply to your PM.  The physical conditioning is coming along, but I'm still not where I want to be.  If I can continue hitting it hard, another couple months and I should be there.
I'm following the fuse thread.  I will probably order a black for the CSL in a week or so.  

Bill,
I don't think that you will regret that purchase. Let me know what you think of it.
Charles, 

Charles,  It looks like the fuse in my CSL is a T7AL, which is a 7A slow blow.  That seems like a lot of current for a preamp.  Is that what you ordered?
