Thank you kt315

I remember a TV from Soviet Union (krimp 218 it had a lots of kt315G :-)

Thank you KT315!

Here is my first attached image:



I am beginning to make a Deltapulse. I have use a breadboard to test the driver circuit (timer + power). I used a function generator to created a pulse at 120Hz (1.2% duty) and ~100uS (pulse width)


The coil is:
25 cm, 25 turns, 0.5mm wire -> 506 uH, 2.0 Ohms


This is the pic taken from the oscilloscope; I would like to know if that is what I have to expect from the circuit; it was taken with the scope connected to the damper diodes.

[kt315]

to expect from the circuit --- ITMD was written for beginners. ITMD is perhaps RTFM for breadboarders.

ok. what you have to see on limiting diodes? the limited 'delta pulse'. good start for understanding what is delta pulse in Delta Pulse.

[nncu2020]

What is ITMD?

I attached a picture with the wave forms taken from VD3/VD4 + R6 (1K0). I would like to know if that is what we normally see when the Delta Pulse is working Ok?

thank you much, Carl and George. i always know that it was just mistake to close this thread.

I build it. Simple is a very good machine especially with large coil

Ihi is the schematic for the delta pulse here? I see a link above you here in the thread should I follow it?

I still have to make a proper coil.

i think he wants LRL detector with automatic attached shovel - seeking the gold itself and digging itself. just seat wait and smoke weed.

One question to KT315: I am looking at your red board and I cannot find the location of R59. The question arises: Have you combined R59 and R60 into one point for housing shield?
