TLA Fat 2 Calibration and Modification

[lame_turtle]

After extensive searching I could nowhere find the service manual for the tla fat man 2. I'm trying to calibrate the unit (it has about 8 trim pots) since it is not working correctly, and then I will try to modify it for the better I hope (I will attach photos as soon as possible).  I know TLA went bankrupt but I did remember they had the schematics on there site which now seems dead .  Do you know maybe who bought TLA if anyone or where I can find the service manual and schematics ?
Does any of you have those ??
I'm stuck here.

Thank you very much

I think I had to contact HHB some time ago for a different schematic. They actually sent me the TL Audio version because they are all the same where they had the versions...HHb Radius 3 was a Fatman 1....etc.......Maybe reach out to them? Looking more it looks like the HHB Radius 5 should be the same as the Fat2 so, chances are, they will have everything. They don't deal with them anymore but have the documents....

I'll look around......

What's wrong with yours???

Good Luck!

This is great info thank you very much.
The real problem is that I have to max the input gain for the presets or the manual compressor to come in, which is kind of unexplainable to me.

I can only say a huge thank you. Starting calibration right away. Again, thanks

Took some time but it finally works great. Just finished calibration on both unit and vu. Sounds nice and displays correct values.
Actually the process is straight forward . Test signals on specific dbu's are needed as always, more dbu readings plus a distortion reading (for this I used my 1054z's FFT but I could have probably gone better by just using my sound card).

Now I'm studying the schematics for possible modifications.

Again thanks for the schematics and service manual.

Sorry for bringing up this old thread,
I am having an issue with a TL AUDIO Fatman FAT-1, the left channel is dead.
I could not find any service manual,  I tried to download the  schematics for the FAT-2 that were posted  in this thread but unfortunately the links dont work anymore.
Does anybody have the service manual for the FAT-1 , or can anybody please reupload the  FAT-2 schematics and calibration procedure?
Many thanks

Hello,

Many thanks.
