There is no clickable link in akolegov's post. If you're seeing one then you have spyware, adware, or some other form of undesirable software on your PC.

  The link works fine for me this morning. Those look like GE 6550A's. I have a quad of Sylvania 6550's and they are actually MO KT88's. I don't think Sylvania made 6550's or KT88's.

    I'm using Chrome on a PC and for me, that isn't an active link, it's a hypertext address which needs to be copied and pasted into a new window to access the page. Maybe with a different browser and/or on a Mac it'd work. The link URL below is active and clickable on my machine.
    
    As to Sylvania not making the 6550 type tube. Issue 19 of Vacuum Tube Valley devotes a good deal of space to the 6550 and KT88 types. In an article by Charlie Kittleson (copyright 2003) entitled "6550/KT88 Shootout: Hi Fi" he states, in part, regarding the Sylvania 6550:
    
    Philips/Sylvania 6550
    In 1971, responding to the demand for 6550-type tubes, Philips (Sylvania) introduced their version of the 6550. It is the smallest size, compared to other 6550s, and has a straight-sided glass envelope. Sonically, the Philips 6550 is warmer sounding and more like a super-sized EL34."
    
    The OP states that he didn't care for the EL34 in this application so perhaps he may wish to pass on the Sylvania 6550 given the above reviewer's comment.

    I am still curious but I question the need to order these tubes (I'd rather order Ei KT-90).

      "I am still curious but I question the need to order these tubes (I'd rather order Ei KT-90)."
      
      To me the Ei KT90 sounds very similar to the EL34 in the mids but with much better bass and highs. Fantastic sound IMO.
