Circuit power tube current is particularly large
Where are the two feelings are self-excited
The three waveform test points are those few points
How four det / BAT switches should be chosen (which circuit should be destroyed or reset)
Five audio is too high, right?
The six sounds are too small and should be enlarged

Another question is how much voltage the LM357 should be on its six-pin counterpart

Hello, my friend, I made this machine, but now some of the above problems have arisen, asking for your help. Thank you

Posted on: November 09, 2017, 11:36:08 am
Since the author created this probe and published this book, I hope he will not mind our discussion and try to do it.
There are many errors in the electrical scheme that may be intentional or unintentional.

Motherboard does not contain platinum module
Error: Transistor T4 (2N4126) Collector and Reverse Counter
Transistor T5 (mpsA14) Collector and Emitter Reversal
