Tesoro Tejon Heeeeeeeeelp!

[eduardo1979]

"Hi all, i have not long had a tesoro tejon and would like to make a modification if its posible, its to do with the sound.
If i pass an object close to the coil it sounds very loud, the further away the object is the lower the sound. What i would like is a constant sound regardless of if its close or distant, if anyone could sugest a small circuit or mod i would be gratefull, Regards"

It is normal behavior. Same as at any other Tesoro and many other models and brands.
But if you really insist than look up for "monostable mod" at Tesoro Golden Sabre thread.
Try to trace out Tejon audio stage and post that part of schematic here.
Looking at it we can dig out some even better solution.
Take shots of Tejon inside. Take close hots - macros, and post here.
Regards!

B L U R ! ! ! USELESS !!!

[eduardo1979]

Sorry, I do not have another possibility! If we adapt an audio oscillator to the exit go to work?

As simply, make earphones with limiter. This work very well.

I have proved it and without result. Thank you!

[ivconic]

That's why i said you have to trace out...at least audio stage. Trace it out and post here that part of schematic. There are no other ways..

[eduardo1979]

I have to find something that makes the constant sound, a limiting and an audio amplifier.

As told before; monostable mod from TGS thread. But it has to be connected before last audio driver at Tejon.

hi-tech espionage is not your vocational aptitude... it's clearly... you may only loudly speak (like to heeeelp!) but need in un-loud detector sound... you need in Automatic Sound Tuning Amplifying... or have to limite a signal in pre-end stage opamp...

just turn threshold up full,works on cibola,trident and most of the other tesoro/laser machines or is it diff on tejon ?
