Ok, if you playback the testtape, you have to adjust the internal level to 675mV (with this 250nWb tape) @9,5cm/sec
The internal level you can measure at the adpapter board

or on the input plug for the phones amplifier

Hi Mampfi,

Still waiting for my level test tape.
In the meantime, could you explain the role of R1/R3/R5 and R2/R4/R6 trimmers on board Y for recording ?
Thanks in advance.
Regards.

Very clear !
I'll use the adaptater board.
Nothing to do with other trimmers (R88 + R99 on board D and R13 + R14 on board G) ?
What are their role ?
Thanks

Hi Mampfi,

I bought the tape.
I should receive it next week.

So if my understanding is correct, reading this tape at 9.5cm/s should provide a -3dB level on the VU meters, as it provides a 250nWb signal, right ?
To adjust, I have to tune R53 and R54 trimmers on board G but also R61 and R62 on ...

Hi !

Got it !
The tape is still available but it seems to be IEC2.
Is it compliant with the TS1000 ?
I thought IEC1 was mainly used in Europe.

Kind regards

Hi Mampfi,

Thanks for your answer.
Anyway, the TS1000 I get was already no more calibrated and I had to replace some trimmers during its restoration.
So, I'm starting from scratch !
Unfortunately, I have no pre-recorded calibration tape, and the cost of a new one is a bit dissuasive...
How can I ...

Hi al !

Now that my TS1000 is fully recap and new belts are installed, I'm working on calibration and I would need your support again.

I applied the folowing sequence :

- Feed a1KHz / 1.5V (2.12V peak 2 peak) sine wave signal to the Universal input (I used a lab waveform generator)
- Select ...

Hi Mampfi,

I'm going to follow your advice !
I only sprayed some WD40 on it, but maybe not enough !
I'll let you know.

Hi all,

Thanks for your answers concerning the playback.
About the preselection counter issue, I opened a new topic here :

Thanks.

Hi all,

On my TS1000, autostop feature does not work with the preselection counter.
The issue seems mechanical, as when I activate the electrical switch manually, it stops perfectly.
But the small plastic piece that pushes on the switch does not move at all when the preselection and counter ...
