I have two, 212 Craig tape recorders that ran normal, until I used a 9v ac adaptor on both of them, & took out a component that makes it run in ff mode only, no play or rewind. The rewind goes to ff.
I checked my universal ac adaptor, & it was actually giveing it 14v 500ma, when the specs called for the ac adaptor to be 9v 100ma, so obviously took out something like a voltage regulator transistor.
The schematic is included with the instructions, shows 7 transistors in it, but I only see resistors & caps on the small board. (This was manufactured around 1965).
I replaced the belts recently, & was running normal for a few minutes on the ac adaptor, until I figured out, I should have payed attention to the actual dc out put of the adaptor.
Any idea of what to check for first?
