Tape output

[vincy]

I have built a balance line stage preamp and would like to be able to connect a tape deck so that I can record from the output, as well as having an output connected to the power amp. Any ideas anyone?

Tape out is a simply an output after the input selector (in parallel to the actual preamp); to avoid loading down the previous stage, check that your tape deck input is high impedance, or better (more general) build a B1 as buffer in between

Thanks h_a, I have looked at the B1 on passdiy. Is the volume control necessary, as I would need a fixed input to my tape deck?

No volume control necessary, it ensures only a high input impedance

But that's already the perfectionist level, you can start right now by simply paralleling tape out after your input selector - chances are good your tape deck has a high input impedance.

Hi,

you could also wire the tape-out in parallel to the input-selector as proposed above but put a 10k R in series with the output. Some commercial products enshure like this that the impedance will not go below this value for the price of some dB dynamic range at the tape output.

Could be a good solution.

Best regards

I have found out that the input impedance of my tape deck is 40k ohms, so I should be OK to parallel the output.

Question about tape output.
I'm using a B1 that I built as my preamp. I need to add a tape out. I need that signal to be buffered as well but to be independent of the attenuator. Can I simply split the input signal sending one line to the attenuated buffer and one line to the non-attenuated buffer?
Thanks.
