Hey guys
 
I'm looking for a tube recommendation for my LCD3.
 
I want to keep the bass tight, sweeten up the mids a little bit, and then maybe add some excitement to the 3-5k region without increasing 10k
 
Is there a tube like this?  This is specifically for the Mjolnir2, but the same should apply
 
I was thinking Telefunken but most people seem to say Telefunken doesn't do much for the midrange
 
Should I be looking at Siemens?

Single Jan. 1958 Heerlen pinched-waist E88CC.

That is going to go for big money, got the new tube insert I NEVER seen first hand.
 
 
 
Used CV2492, Brimar? $46.94 pair.

Linked this Telefunken "CCA" few weeks ago but no response on if it is a real CCa or not, just curious for some responses, not looking at buying.

I received three pairs of BRIMARs recently, and based on all the research I did into codes and whatnot, the consensus seems to be that BRIMAR tended to use "Made In England", whereas Mullard, et al., used "Made In Great Britain" or some variation on "GB".  I love how the seller says, "Please see carefully the photos"... they're rubbish, and not just because they're out of focus.  Still, a decent price.
 
All three pairs I have use a date/type code like, for example:  3G4/3910, which translates to Week Month last digit of year/type code.  I've seen 3910 listed as "6DJ8", of which E88CC is a variant of sorts (roughly(?) the same electrical specs).  One of my ECC88 pairs has 410/1778, but I've yet to find a reference to 1778.  Didn't blow up the Lyr, so whatever.  The "year" digit is typically problematic: are mine 1960 or 1970?
 
The interesting pair are "Sylvania" 6DJ8s with gold pins.  Maybe they're really E88CCs mislabeled.  Internally they're all nearly identical, except the ones labeled BRIMAR have "gold" rods protruding from the upper mica, whereas the "Sylvania" pair do not.  The latter sounded pretty good in the 24 hours I gave them.  None of them can touch the sound stage of the 6SN7s I switched to, but the BRIMARs have that nice, weighty Brit. tone.  I tried mashing them together to get the perfect combo, but just ended up with bloody hands... j/k.

Thanks guido. You too and have fun with rolling,

 
Sammy's on a strict Tesla diet.  Inhumane...but effective.

I'm using some Orange Globes I got a while ago. I switch off with LiSST depending on my mood. I basically want LISSt with better imaging, detail and lusher midrange. Actual tonal balance is decent besides seeming a bit V

 
Cheapest way to go for the lusher midrange might be a Dutch Philips or Valvo E188CC.  Certainly a grey shield Siemens Cca or Telefunken Cca or E188CC would be vast improvements over the Orange Globes.
