Similar circuit on web has R12 = 20 ohms so likely that R12 = 6 ohms. You can use BD139 for Q3, Q4 and BD140 for Q9. For inexpensive power transistors try C5200 and A1943.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6778607571473979269.post-39460721817438641042018-09-14T08:16:00.719+07:002018-09-14T08:16:00.719+07:00What is the value of R12 and L1?..What is the value of R12 and L1?..Anonymoushttps://www.blogger.com/profile/12837070452065458986noreply@blogger.com
