Can you please suggest a schematics?

Any of the octal deluxes (5B3-5D3) sound amazing with a 6SL7 setup. I'm talking thick, full distortion that's perfect for blues and slide and nice glassy cleans with the volume rolled back. Octal tubes have an airy sound to them that I love. It's hard to describe without a side-by-side comparison but they almost have another dimension of sound, as if the larger envelope/plate structures allow more stuff to survive.

Passfan,

Finding non microphonic 6SQ7s is hard and actually these tubes have been hard to locate other then the ususal Ebay sales.
