Threshold FET/10 He Service Manual

[Nounours18200]

Hi friends,

I am looking for the Threshold FET-10 preamplifier Service Manual: does any of you own this document ?

My email address is : nounours18200 (at) free (dot) fr

Thank you very much for your help

Analog Guy once posted a schematic without component values. It is more than sufficient if you need it for repair.

[Nounours18200]

I have sent him an email to get the info he has if he accepts to share it.

The "diagram" he posted in this topic
here

is only a low resolution PCB, but I have not found a complete schematic : and I am looking for the schematics with the components values and types, as I plan to replace some of them to improve it...

If any of you knows a source for the complete Service Manual...

Thanks a lot,

I'm very interested too!

I got a original Threshold Fet nine, it sounds very well and i'd like to give a chanche to a diy Fet-10 too

To date, I have not succeeded in getting this Service Manual:

-I have e-mailed almost all the websites supplying service manuals: none of them has it
-I have posted a lot of messages in various high-end audio forums, but no success
-I have sent a request to Threshold Audio Inc: no response yet (but I sent the mail just yesterday), but they will probably reply "ask to an official Threshold service office"....: not convenient for us.
-I have send 3 requests to Jon Soderberg from which I got other Service manuals in the past (he is a very nice person and his service manuals are excellent), but he has not replied to my mails: maybe he is on vacation.

it looks like if nobody has this "bloody" document ...

Any suggestion is welcome !

well - if you send me one FET/10 , I'll back - engineer it ,and write service manual .

and I'll send you Fet/10 back ................

maybe you can ask some of your country man DiyA fellows to help you in back engineering .....

for start - you can make few ( as much you cant) pics of it and post them here ;

you can even mail big ones to me - I can shrink them , in case that you can't .

Yup. I'm with Choky. Reverse engineering a simple device like this is trivial, fast and easy. And not nearly as humiliating as begging for a freebie

The circuit is available - just read the component values from your unit.

OK ! As soon as I am back to home after new year, I will take a lot of pics that I will post here (I had already planned to take pics for myself) so that we can work on this together).

Thanks to all, and happy christmas !
