Don's Compact 300B Amplifier

Don has build this exquisitely compact 300B on one of his fine Spotted Gum bases. He uses ABS for the top plate with no bottom plate. He doesn’t believe in them. The 300Bs and 6SN7 are Chinese made “Electron Tube” – Shuguang . All components underneath are high-end. Though Don is on a pension he always uses the best passive parts but skimps on the tubes. The rec. tube is a Golden Dragon 5U4. The horizontal power tranni, OPTs and choke are locally wound by Dyne and are expensive. The best amp I have heard of Dons is his 2A3 which I intend to re-borrow. This amp is new and may improve with time but for now both the top end and bottom end are a little crippled. Mids don’t sound fast and slightly masked. BUT this may all change with time. It does play very loud though on a large 3 way Osborn Eclipse @91db efficient.
