On page datasneet of the datasheet, the bias oscillator is missing, is that DC biased then there’s just a filter with unmarked cap and resistor?

I’d like the most simple solution, which could be easily put on a daughter board and hidden in the tape recorder. Andy aka k 10 Sign up or log in Sign up using Google. A single package contaning preamplifier, ALC circuit, power amplifier.
Information including circuit diagrams and circuit parameters herein is for example only; it is not guaranteed for volume production. It looks like the circuit in page 3 will not be able to record anything in acceptable quality, but it can be a mistake in the datasheet itself. I think somewhere around datashret makes the most sense.

Specifications and information herein are subject to change without notice. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer ‘ s products or equipment. The products mentioned herein shall not be intended for use for any “special application” medical equipment whose purpose is to sustain life, aerospace instrument, nuclear control device, burning appliances, transportation machine, traffic signal system, safety equipment etc.
On the other hand, it may not work because the “simple” resistor circuit above may cause the amplifier producing the regular record signal the audio to clip and distort.
Check the type of your recorder erasing head. It is possible that these probabilistic failures or. LA is Single-chip tape recoder audio system. Anyway, it’s better to replace it with a ferrite erasing head because it demagnetizes the tape and prevents it from producing low-frequency saturation noise. An Example of Printed Board Cu-foiled side.
The bottom line is try it and see and if it doesn’t work then no harm done. Sample Application Circuit 2: VG pre 20 log Z1 dB.
When designing equipment, adopt safety measures so that these kinds of accidents or events datasehet occur.
Since the output stage is of push-pull type, no remarkable drop in the output voltage occurs even at.

It’s likely just a permanent magnet that saturates the magnetic tape in one direction. Given the rest of the Datasheet, I might be able to locate the point where this oscillator has to go.

I was thinking using a 70kHz oscillator, and adding it to the signal somehow before the DC bias, as in, removing the DC bias parts.

Such measures include but are not. The bias current is several times higher than the recording current and also its frequency is higher. If there is no consultation or inquiry before the intended use, our customer shall be solely responsible for the use.
I don’t know which peak-to-peak level, and I’m not entirely sure what frequency. An erasing head is commonly attached to the generator directly, and a secondary winding of the transformer is capacitively coupled to the recording amplifier output.
