I got a Christmas card from Putin!   He's loving his Voskhod fed Lyr  

Anybody recognize which HP's Vlad is listening too? Jamming some Marylin Manson......

Not to 

 too much, but I found this quote:
 
"...labeled KB/AD, with the AD designation indicating the vacuum pumping process was completed in the Thorn-AEI (Brimar) Rochester plant.."

Thus:
 
AD = Thorn-AEI (Brimar), Rochester

  Well, my CV2492s are not labeled EDISWAN or any other brand, though they did come in the real red and yellow Brimar boxes.

 
I don't see any evidence of any brand on Upscale's so-called Ediswans either. I do see KB/AD in the photo.

 

[Oskari]

I need to try Ediswan cv2492 sometime. This hobby real does drain the wallet lol

 
Don't get too hung up on brands, guys. The manufacturer and the factory matters, a particular silkscreen does not.
 
Ediswan and Mazda (UK) were AEI brands. Thorn bought Brimar from STC in 1960. In 1961 Thorn and AEI merged their tube interests, including CRTs, in a joint venture forming Thorn-AEI. A tube made at the Rochester plant could carry any one of the brands.

Thanks for the information. I appreciate it.

Hello all,
I have been reading this thread over the past couple of weeks and covered a bit of ground. I purchased voskhod rockets and in the process of burning them in now,

I am interested to hear about your top 3 tubes for the lyr / lyr2 for best sound across different genres: rock, jazz, vocal, etc. I realize that some tubes are better suited for one genre over another, nonetheless, from a practical standpoint what would be good tubes for all.

Look forward to read your responses,

If anyone's looking for some Dario Miniwatt E188CCs, here's a pair on Italian eBay.  Not a bad price:

Not sure if the "VR" code is VR1 or VRI.  I know my wife writes her 1s like that.  So, they could be 1966 or 1976.  The 'F' factory code means they're from La Radiotechnique in Suresnes, France, not Heerlen.

There was a French Mazda brand which was unrelated to the Brits, just to make this confusing hobby even more so

Just realized I should have posted this question here: Could anyone do me a favor and point me to a recommended warm sounding tube for me to drop into my new Lyr 2 and where to buy it?  I really like warm sound and don't know what to make of a lot of the tube discussion in here because it's all new to me and I'm trying to avoid getting too deep into it.  I just want to drop in something to sound warm and good for me equipment (see sig) and forget it.
 
Help please! (and ty in advance)
 
edit: also happy to buy from Head-Fiers selling goods.

I have some 77 6n23p grey shield Voskhod's. $40 shipped. They're definitely a warm tube. But still deliver some stellar details. And a good 3d , holographic soundstage. They're a top 5 Voskhod on rb2013's rankings. http://www.head-fi.org/t/736428/1975-reflektor-swgp-silver-shield-6n23p-6922-6dj8-holy-grail-matched-nos-pair

You might like the British tubes (Mullards, Brimar, et al.).  I've got three pairs and another on the way, and they live up to their rep of being "warm."  You can use this list
 
http://www.head-fi.org/t/673709/schiit-lyr-tube-rollers/4215#post_11159200
 
to determine the equivalents (e.g., CV2492 = E88CC/6922) by googling for it, but eBay sellers often list the equivalents in the description to get more hits in searches.  No doubt veteran rollers in this thread can give you a better/enhanced answer.  I'm diggin' the "Ediswan" (probably Brimar) 6BQ7As I got from a Spanish eBayer (http://stores.ebay.com/cryogenichifitubeslamberto1111), and the E188CC 7308 RTC made MULLARDs I got from http://stores.ebay.com/frauolia/ aren't bad either.  Both were well under $100; barely over $100 for both pairs.  Can't promise they still have them, but it's worth a look, if you're interested.
 
Mullard ECC88s are pretty common, and you should be able to get them under $100.
 
HTH.

Thanks for the heads up, I will be checking eBay for "Ediswan/ Brimar" cv2492 tubes. Have a great New Year.
