Hi!
I have an old reel-to-reel home recorder (late 60s).
I would like to record some tapes to PC maintaining the highest quality.
Since it has valve amplifier, I think the best way to get the signal is right at head output before any kind of signal amplification.
The question is: can I do a good tape head amplifier using only an opamp? If yes, how?
I would not like to buy a tape head amplifier IC until necessary.

hi David,
it is possible to construct a tape head pre amp, however this is not a straight foward job, the pre amp has to have tape EQ compensation and there are a few different specifications for this.
this along with the low noise and small signals involved make it quite a job.
how is the sound of the machine you have?

A tape head amplifier is very similar to a phono preamp. It just uses a different equalization curve. They use to be very common at one point. Even the old Dynaco PAS3 had one. The equalization can be done passively or actively like RIAA in a phono preamp. Below are a couple articles about building them.

Wideband so you can gets lots of gain from a single chip and not attenuate the highest audio frequencies.
