I have: Used Quad of Sovtek 6550WE's I want: LEGO bricks. Background They came in my Traynor YBA 200, and were the stock model tubes for that amp. They sounded fine, but can't (IMHO) compete with the JJ KT88's the amp now has for tone. The amp has since been upgraded to remove the "auto" bias feature, and changing tubes will require similarly rated KT88's or a rebias, so I have no use for these 6550's anymore. I want LEGO. -If you have loose LEGO, then I'll ship the tubes in a standard size USPS flat rate box. Fill the box with LEGO bricks (any kind, but no off-brand stuff) and send it back to me as payment. -If you have something special (complete kits, etc...) shoot me a PM and we'll work something out. As long as you're not too sketchy, I will ship first. Tubes will ship in JJ electronic KT88 boxes, which will be shipped well padded inside a larger box.
