Manual for Marconi TF2000

[Fool2cool]

Hi,

I've just purchased this unit non-working and I'm struggling to find any circuit diagrams or manuals online for it, does anyone have a manual or circuit they could upload or email to me?

Thanks
Charles

This is all I can find.

Yeah I might have to bite the bullet and buy it, I'm a bit begrudged to pay a company for something like that though, if I do end up buying it I'll be sure to post it here.

Thanks for taking the time to look

Have a look at the oscillator part of the Marconi TF2331 Distortion factor meter, whose schematics are available online. It covers the same range in the same frequency bands so might use the same or similar circuit.

I am not too happy with Mauritron, They had for sale on the well known auction site a PDF of a manual for the Gould DSO400 that I scanned and shared free a manual site.

I emailed them and had a go, so they removed it.

Dickie, as far as I can tell the TF2331 doesn't contain an oscillator?

Thanks

[Dickie]

Yes you're right. I dunno where I got that idea from

However, I also have a TF2000 (fortunately working) and although the individual modules are not identified I am sure they are a TF2100 AF Source and TF2160 monitored attenuator. Assuming that this is the case both of these modules are covered by the TF2005R manual. TF2005R comprises two AF sources and one attenuator.

The TF2005R manual might be available from other members of this forum if you ask them nicely. See

Thank you! My colleague at work actually just made the exact same discovery and found the manual listed on google, I'll post a link here when I grab it!

I've managed to dig the circuit diagrams up out of the abyss, they say TF2001 on the bottom but seem to match perfectly. Is there anywhere else I should post these to make sure no-one else struggles?

[Dickie]

Thanks, they will be useful. But note they say TF2100 on the bottom. You might like to rename your pdf to avoid continuing confusion!

[Fool2cool]

Oh is it 2100 I knew it was something like that! Oooopsi

For anyone who is interested in distinguishing the instruments discussed above, I attach images for:
TF2000 AF Signal Source
TF2005R Two-Tone Signal Source
TF2100M AF Ocillator
taken from the 1975-6 MI catalogue

As Dickie says, the TF2000 contains a TF2100 module, and the TF2005R has both. The 2100 would make an ideal source for use with the TF2331 Distortion Factor Meter.

Aha, thank you Julesomega,

Have TF2100 SN/52398/39 and always wondered why Marconi would make an instrument without calibrated output as in TF 2331A. mine is in its own enclosure without options. Measures 0.03% @ 1000Hz distortion on a Hameg HM8027. Would love to see schematics.

Regards all

Hallo Renato,
you can download it from hier_I think its usefull for you.
Sincerelly, Karl
