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.

Sorry to bump out thread, I want to do the same thing and my tube amp doesn't have a tape out. This is the specs of the decks input for the recording. Any help would be great.
You mean sound source. the only one I'm using is the Bluesound node 2i and I can adjust the volume going out to the RCA as a preamp out. They didn't give an actual number beside the specs.
Audio Output
Analog RCA Stereo Coaxial RCA volume controlled variable
Native Sampling Rates
32 - 192 kHz
Bit Depths
16 - 24
NODE 2i - Bluesound
I was able to record in my other amp for it has a tape out using the same bluesound node 2i source and it worked fine.
What do you think?

Check the output level, since it can overload a vintage deck input.
In that case a pot or a resistive attenuator is needed.
Many decks from that era accept only 350 or 750 mV at 0 dB VU input level.
Just connect it to the tape deck and check if You can record without distortion.

okay so if I understood since I don't have a tape out on my amp, I will Y connection (parallel) the audio source which is the input going to the amp then go to the tape in of the cassette deck. I was concern if its gonna affect the sound of the source since in splitting the sound into 2.
previously I have recorded on a preamp out using the same source but that was coming out of the amp and it was fine. So basically this is like bypassing the amp.

I got confused when you mention recording from the amp. I assume that it's some sort of integrated amp. Correct me if I'm wrong. Can you describe your set up in a bit more detail?

Are you using another analog pre-amp or are you running the Node 2i directly into your power / speaker amp and using digital attenuation with the Node?

ans:
From the node 2i rca output, then plugged in to the primaluna integrated amp rca input (nothing in between the 2), then primaluna integrated tape out directly to the cassette deck in and I was able to record fine.
"previously I have recorded on a preamp out using the same source but that was coming out of the amp and it was fine. So basically this is like bypassing the amp."
ans:
Same process as above mentioned but this time the integrated amp doesn't have a tape out. So I was thinking if I will have to Y connector right between the node 2i and integrated amp going to the cassette deck input.
All results of my cassette recording are analog. the node 2i has a built-in dac.

The addition of the word "integrated" is important.
Either way. If your tape deck has an input level adjustment, just run the Node into the tape deck with a Y connector like you describe. The other side of the Y connector to the pre-amp. Run the Node with no digital attenuation and set the input level on the tape deck (if so equipped). Check levels on the tape deck using VU / LEDs or whatever is on the tape deck. Give that a try.

Any time. Hope it works well. Also, if your tape deck has a "record out" (almost all of them do), you can run that back to the pre-amp / integrated and listen to that signal for distortion etc. You probably knew that, but just in case.
If that doesn't work well, post back. Others may have some better ideas.

its should work. the main thing I was also shooting for is when you do the y connection (parallel) does it affect the sound at all like getting loose or "monoish".
I was just cuirious what is the real inside circuit of an integrated amp with a tape out.
If its just "basically" like a Y, then that's great.
I have recorded over hundreds of 90 minutes tapes I prefer the sound more this way than most cd's. Nothing better of best but Its just a personal preference.
Both my nakamichi and old sony 3-heads does a wonderful recording job.
