Aquatarkus Posted December 26, 2012 at 11:13 PM Report Posted December 26, 2012 at 11:13 PM Could not see the characters clearly (in my opinion something like 三极管), but overall schematics seems very similar to Colpitts oscillator I think you can use any ordinary NPN transistor like 2n2222, but values of resistors and capacitors depend on desired output frequency, which is unknown.
