Sir. good practical knowladge. But dir it could be a better explanation and illustration by circuit diagrams

Also, on schematics, there is a conection from bias oscillator to recording amplifier. Why is it so? Shouldnt the bias benfonnected justo to erasing head?

I have too much noise from the dc motor. Do you have any tips on how to remove it?

Make power supply for DC motor and Preamp Head separately.

Friend, can you send me a bias oscillator finished circuit because, the circuit I made is not working. I may send the cost and C.C.

What is Value of Blue Bias Oscillator? Please Help Me, Sir 🙏

What happens if you don't use bias

B-H Curve of magnetisation and demagnetisation of magnetic tape is not linear at some regions of the curve. For distortion less recording it is necessary that recording characteristics should be in linear region of B-H diagram. Hence we apply AC or DC Bias to recording head, so the recording curve will be in linear region of B-H curve and during playback of recorded audio we are capable of reproducing high quality of audio signal. Frequency of AC bias is always kept higher than audible frequency range.
