When the power is 9V then TIP127 not heated, and of course the coil L=450uH and R=1R5.

thanks jap i read the original literature/reviews and i understood it as iron tone identification
and earlier on in the thread alexmex was it seemed to me screaming at us "its due to the tip27"(though noone in the thread was listerning to much off topic nonsense)
plus i'm not having that "the switch/trans is unknown" i'm positive the collective brain power of this forum can crack it if properly stimulated as for sinclair
at maikl i designed my barra to run 9v anyway(with the option of going to 10.2 by adding another aa cell

Barracuda problem
Hi
I have build Barracuda from silverdog and after i play with it a few seconds, the detector starts to make an intermitent beep beep beep every two or three seconds.
I rechecked components placement and values and this are correct too
Battery is fully charged and coil is the correct one. Any ideas of what could be wrong?
In advance many thanks
Nelson

Hello Volcano, eliminated 270K resistor ic pinout different from LF357 NE5534, iliminado "offset" because I do not have the original ci.
Attention: The PCB has been modified to correct the use BF245C pinning.
