jung-415 surface grinder -- Circuit modification
A German grinder will be purchased in 2021. The electronic circuit is old and some minor faults will affect its use. Determined to rearrange the circuit himself.

Yes, there are some! However, with the strict regulation of speech, there are fewer and fewer forums, and even now the only remaining forums have to be very careful to speak, and the atmosphere of the forum is more and more utilitarian swamping the space for easy and free discussion! So, I chose here!!
