Thanks Paul, that was very helpful. I do like very dynamic music, at pretty high volume. For example, I like Peter Gabriel's "Up" at pretty high volume with my Straight 8s. Other artists I like are Patricia Barber, Jennifer Warren, Keb Mo, too many to mention, tastes all over the place. I find my single ended 8 watt amp a little lacking, so was looking to take it up a step, to a 15-20 watt PP. Sounds like pin stripe might be the way to go, a little of both worlds.

  My experiences with the AS-250...
  
  I got a pair of the AS-250 units (M4 I guess, no nickel was offered at the time) when Mike first offered them (mid '90s?). I combined them with a pair of the MQ/Peerless Altec 17173 centertapped driver chokes and made a Brook 22A clone. (WE396 input amp/phase splitter, 5687 driver, Sovtek SP 2A3, no NFB). This made one great-sounding amp. While my speakers are quite efficient, this amp sounds more powerful than the 80W solid-state amp I was using previously. Even with zero feedback the bass is well-controlled.
  
  If this is a relatively-simple coil wind job (compared to a 20-20 series unit), it might make a good budget offering. It sounds good to my ears, anyway.

    neat. I was just stacking a few pairs of these today from a newer run of AS-250's. These are really nice designs.
    
    A topology such as you describe is so easy and straightforward... that with good tubes, good iron, good layout, etc... it would just plain have to sound quite good.
    
    And funny you mention about the nickel.... I actually stacked one pair with all nickel lams. Did one other pair with M4 lams... and a third pair with M6 laminations.
    
    I'll probably be putting these up for sale very shoortly---- look for an announcement over the next few days or so.
