In this effect they used some realy old fashioned MP41A germanium transistors ( although here dated 01.81 they're already to be found in a 1968 transistor receiver) , with the battery positive to the ground.Others transistors are KT203B ( or KT203V) .From both I have found some data sheets ,those aren't the problem , the other are ! The're two with only "G"(in cyrillic) marked on them and another with KD302BM ( or KD302VM) I wonder what that last electronic device is , because it's marked on the pcb with cyrilic E , I and K ,not E B K as usual transistors .The "G" marked are transistors due to E,B,K markings on the pcb.Those "G" 's can also be found in Formanta , Borisov Solo II & Bass I . Do you know something about them ( those "G" and KD302BM ), have you some data about those ussr transistors ...or if not :do you know someone who has ? thanks !

| Гость | Hi, sorry for my english. Are you sure that кд203 is a transistor? So usually denoted by a diode. кт - Кремневый Транзистор (silicon transistor) кд - Кремневый Диод (silicon diode) for example: [link] | ||

The metall-oxide-semiconductor field effect transistor! Analogs of components: МП41А - 2SB175, AC542, ОС75, 2N2428, 2N369, 2SB120, 2SB175 КТ203В - 2N2276, 2N2277, 2N2372, 2N2373 And at last, КП302В - 2N3972, MFE2098(but other body) It so easy... Good luck! [ Редактирование 18.04.2011, 19:13 ] Japanese-Manufacturers-of-Made-In-Japan-from-1950-to-1980 Обмен - [link] Менялка педалек Заштатная сволочь. | ||
