'70 Teles e88cc
'68 Teles ecc88 - military stamp
'80's Siemens e188cc
'59 Siemens 6922 - Stamped RCA
'60's Amperex JAN - White Letter
'70's Amperex 6922 - Green Letter
'60's Phillips PQ (Holland) 6922 - Pinched Waist
'75 6n23p Reflektor HG's
 
The result? Nothing compared to the '75 Reflektor HG's. It had the smoothest presentation, widest soundstage, and tightest bass.

Wow that's awesome! Thanks for the post....
 
Dude, I may just lay low for a few months enjoying the HGs and focusing on something other than tube rolling

No worries -  I've done that on and off many times over the years.  But after hearing how good these are - I've always been curious as to how they compare to the Great Siemens CCa's.  Read Nightflight's ad for the Voskhod '75 grays - his description.  Says a lot.

 Up for grabs is this pair of Giant Killers. They hold themselves pretty well up against the the Siemens CCa 6922/E88CC tube in terms of dynamics detail and space. Almost as holophonic as well. These were sold to me by rb2013 as proof of concept against the Siemens CCa and they do hold up. I didn't fully break them in - sitting at around 100hrs. Rob and I both came to an agreement that they will need around 200hrs to fully break in and sound their best.

Now those were the previous #1 6n23p.  Before the HG and '74 Reflektor SWGP Silvers.  So now the #1 Voskhod but #3 6n23p.
 
So the big question - can the HG's meet or beat the sound of the Siemens CCa gray's?
 
Well - I hope to soon find out.

I'm finding the Lyr with my Alpha Dogs to be a bit upper-mid-forward - almost a little nasal.  Tried rolling in some Pope PCC88 (rebadged Amperex Bugle Boys), and they're better, but haven't changed the sound signature much if at all.
 
Anyone recommend some good tubes that recess the upper mids a little?
 
Cheers,
Dunc

I would try the Amperex tubes. How much do you want to spend?  They range from the OG's for around $40 to $250 for my favorites the USN-CEP 7308 White Print's.   The OG's will be more recessed - the CEP's a bit more forward - in the mid's.   But an excellent tube should not be nasal.
 
My experience with most of the PCC88/7dj8's has been pretty bad.  I tried the Lorenz SEL and the Siemens PCC88 gray shields - they were quickly sold.  Not all though the - Lorenz Stuttgart fused mica's I had were very good.  Also very rare and expensive.
 
PS YMMV!

What Bob said, and I'll add some Mullard/Brimar/British-made ECC88s.  They're available on eBay and from some UK-based sellers who aren't necessarily on eBay.  They'll run you about $90-$110 a pair most likely.  Mullard ECC88s have a reputation for a "warm" sound.
 
You should check Tube Hunter (mercedesman) on eBay.  He's got a great reputation and usually has a good stock on Amperex (Philips) 6DJ8s (US name for ECC88).  Some Bugle Boys might work for you.  He's got a few pairs from the early to mid '60s (I checked yesterday).

Good suggestion!  The Valvo E88CC Herleen's as well - in that price range.  Also warmish sounding -recessed mids.
 
+1 on Mercedesman

I got my orange globes from that seller and had a good experience. He has a pretty good list of tubes that works with the Lyr.

I picked up a pair of Telefunken ECC88s for $99 from a Cali eBayer and just rolled them last night.  At first blush they're nice; maybe not as 3D as the '63 Siemens CCas, and haven't compared to the Tele E88CCs from Upscale, but nice.  Early days.  After 100 hours or so I'll compare with the E88CCs (from '68 & '69, so, close in age).  While the ECC88s didn't have any test results, they did come in original boxes with about 95% of the cellophane still on, so I figured they were a safe bet.

After reading the HK tube review - I'm really curious as to the different yrs, factories (not brand! - see I'm learning. LOL!), and constructions of the Brit tubes.
 
They chose the GEC CV2492 - as the best of their group of UK made tubes.  I wish they had a little through description - like year of production - and a picture.
The surprise for me was the low ranking of the wrinkle glass Mullards.

I just got some that have crinkle glass across the bottom - never seen that before in a 6dj8 type.
They are marked 'Made in England'.  No date code I could find.
 
Here is a picture.  I need find these GEC's but have not turned up any yet.

Do you see any codes on those tubes?

I bought the Popes from Upscale Audio, and they claim they're basically just rebadged Bugle Boys: http://www.upscaleaudio.com/pope-pcc88-7dj8/
 
Will check out mercedesman, thanks.

+1 Nice!  Strong lineup there!  Including the '60's Philips PQ (Holland) 6922 - Pinched Waists!
 
Wait until those HG's hit that magical 200 hours mark.
