Ram,
I made the new delta plus in a single day & tested it was ok, because the calculations you have done is already done by the designer of this circuits than why I waste my time, if the circuits assembled  OK , than why there is a issue with circuits
In my delta plus circuits I used 2N3904 transistor between FET740 gate & the 556, it is working well
The circuits is already working , but with small modifications we can do better , 

BR,
Obaid

obaid, you said your dp is working well, why you gave wrong idea to ammen in trouble shooting his dp, is your new dp has 100 ohm resistor in mosfet gate? if it has, that is 100 percent not working well.

for ammen, check schematic, 1led is for power, another one is for low battery indicator.
no sound-check 555 circuit w/c is sound generator maybe solder bridging/also chk spkr connection.

regards,ram,

I would be very interested when you get it all together. Are you going to do some comparison "Field Tests" " & post some "Depth" Testing? I would love to see some comparisons.

Best of Luck!

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.
