Sample Application Circuit 2: Maybe you can help though? A single package contaning preamplifier, ALC circuit, power amplifier.

An Example of Printed Board Cu-foiled side. This is just a little project to play around, nothing serious. It’s la41160 bit like when someone asks if you can fix their TV – I always reply “get me the circuit diagrams and I’ll have a look sometime “.

An erasing head is commonly attached to the generator directly, and a secondary datasueet of the transformer is capacitively coupled to the recording amplifier output. 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.

Preamplifier The preamplifier circuit consists of the input differential stage TR9, 10level shift stage TR13and output stage TR17, 18, But how exactly do I build this thing?

You need to know your recording head’s inductance, maximum recording current and maximum bias current to design the bias generator. It means you need a separate bias generator anyway.

VG pre 20 log Z1 dB.

OK, this is how far I’ve got:

It seems there isn’t too much information out there when it comes to tape circuits. Upon using the technical information or products described herein, neither warranty nor license shall be granted.

The products mentioned herein shall not be. Since the output stage is of push-pull type, no remarkable drop in the output voltage occurs even at low load impedances and the output can be connected direct to the ALC circuit and meter circuit.

It’s likely just a permanent magnet that saturates the magnetic tape in one direction.

It might be no more difficult than making a 70kHz signal and adding it to your “normal” record signal that feeds the tape head.

I’m not planning to make “professional” recordings on the tape recorder that will emerge at dataasheet end of the project. 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.
