Here is a pair of mono block amps based upon the Dynaco MKIII circuit and a pre-amp built around the Vacuum Tube Audio SP-14. Enclosures are black walnut, copper, and brass.

The speakers are Tang Band w8-1808's.. cabinets are MDF covered with walnut and maple. The flared ports are handmade from copper.
