Marconi TF893A Manual Required
I have just acquired one of these instruments, and it is proving very useful. However, I'd like to have the manual. Does anybody have one ? I have seen the 'manual' for the TF893, but this doesn't have a full schematic, and mechanically, it's quite different.
Thanks for any offers. I can copy and return, paying all costs, if necessary. Cheers, Alan G7DCF Islington London |

Hello Alan,
A not so quick Google revealed a free PDF manual - https://docs.google.com/viewer?a=v&p...2I2ZmViYTNmNGE Michael |

Re: Marconi TF893A Manual Required
Hi Michael,
How did you find that ? I'm so embarrassed. The first thing I did was google, and went down to about the 8th page. A few manuals for sale, but no free ones. Thanks very much, Alan |

Re: Marconi TF893A Manual Required
Hello Alan,
More by luck than judgement! It was on Google page 1, third entry for 'Marconi TF-893A manual' (The hyphen was apparently critical for some strange reason.) Michael |

Re: Marconi TF893A Manual Required
Marconi TF868 series. There are several different variants, with fairly significant changes over the amplifier/ chopper circuitry.
TF868 of 1946, TF868/1 of 1955, TF868/A of 1957, TF868B of 1958. I suspect you have found the one appropriate to your model. If stuck, then I have details of all of them. WME_Bill. |

Re: Marconi TF893A Manual Required
Michael,
Yes, it was the hyphen. Something to remember for next time ! Found it this time; the 4th entry, the extra one being my enquiry here on vintage-radio.net. Thanks again, Alan |
