NPN Hot Germanium For The Big Muff
Old-Stock devices. mostly U.S.-made in TO-5 cans. Hfe 200 to 500, but we guarantee leakage under 500 microamps at room temp with base open. Not audited, but returnable unsoldered if hissy. Drop these into a standard silicon build with no power issues! In my tests, re-biasing is optional and not difficult.
