  Recently I made the version of modulaterator for veroboard, I tried it with ZZPD but the LED does not blink . The modulation is heard but not flashing LED
  This is the veroboard wanted to help me find because the LED does not blink. Thanks in advance  ;D

  I check the B.O.M. for the ZZSDX and the Rate LED is a 3mm and in my veroboard i use a 5mm led this could be the problem? that it not have enough voltage?

Maybe the LED is connected the wrong way?
Does it work at all ?

       Thomas sorry for the delay.

       The Modulaterator already works but the Led is not workink yet, flashing at the rate.
       
       I found one error in the Vero Board:

       - The two resistors (100k) that run from the +9V & GND to the pin 5  should go conected to the pin 6.

        Since I Found this error I check my wiring and I found another error, I connect wrong the terminals of the rate pot so i fix it. After that I connect the Board to the DElay 1 Terminal of my ZPDD Board and Work only the Depth Pot  cause when i turn it i heard something (i don't know how describe it, sorrry for my bad english i hope you can undestand me ) but when i turn the rate pot anything happend  and the Led is still not flashing.

         And after that I check the ZPDD Deluxe and i see that the "Opamp LFO" is identical  with the Modulaterator Board and i realize that
    that the ZPDD Deluxe Opamp LFO use it a 1MC instead a 1MB  Rate Pot
