you are wright... i've change the position beacouse the 1st 78l05 i  put, burn right away, so i did check the datasheet.. guess i didn't read it wrigh

i've built a cave dewller  using the etching layout, the pcb seems perfect but, i got no delay, just weak signal, i've made a few changes because i did not have the correct capacitors, changed the 1uf for a 1uf electolitic capacitor, and the 10uf tantalum for another electrolitic, everything else is ceramic capacitors and metal resistors.

with the probe i got signal in pins lpf1-in and out, lpf-2 in and out, but nothing more than this.
can someone help me please?

pin voltages
1-4.3
2-2.1
3-gnd
4-gnd
5-1.98
6-2.10
7-3.92
8-3.93
9-1
10-4.26
11-0.08
12-2.14
13-3.92
14-0.4
15-0.4
16-3.9

5v at 78l05 out pin witch is geting a bit hot
i've noticed that the layout is wrong at this ic, so i've put it wright, i believe....
