[QUOTE="heka2015, post: 159237, member: 7351"] [COLOR=#ffff00]The Transistor Conundrum Part II[/COLOR] Here is the source of this datasheet. Thanks for making me find this usefull gem. [URL="http://www.semicon-data.com"]Ranges and Data-Tables for Semiconductors[/URL] Interresting page, it is a SEARCHABLE datasheet database for OLD components. The "similar search"-link you can see on the pic leads to 30+ germanium SBTs. Don't get too excited it'll be the same to get a hold of them...discontinued for sure. Those are the original manufactures: - Philco (developed '55) - Sprague Electric Company (licenced '56) - Semiconductors Limited, a division of the British-based Plessey Company (licenced '57) - General Transistor Corporation (licenced '59) Yep I am aware of the different uses. Thanks for reminding though. I am trying to get my hand on a box of a mixed collection of vintage germanium transistors. I prefer locally, but ebay is always a possibility. Maybe some russian military grade ones?LOL [URL="https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313.TR0.TRC0.H0.Xvintage+germanium+transistors.TRS0&_nkw=vintage+germanium+transistors&_sacat=0"]vintage germanium transistors | eBay[/URL] Nevertheless I'll get some 2N588 separately, now i know what to look for. The plan is to build the device exactly like yours first, with Philco SBT 2N588, because that is what the schematic says, period. I want to socket the transistor and a connector for the coil to change those without a headache. That would be the only thing. I hope i can get the other parts cleared up soon to finally build that puppy. Working on it! ...to be continued [/QUOTE]
