   I have gotten up to 18 or more leds in series to partially light up on a single diode loop, using 24v from batteries.   I also attached capacitively another 26 leds in parallel, as well. Not directly connected to the series lit bulb's output.
   I'll be adding more diodes to the loop later today.
   Unloaded voltages are around 72 volts, so far using only 5+5 diodes on a single loop.
   
    Gyula, I'm unable to obtain a current reading on my multi meter at the oscillator circuit's input.
    Thanks for the reminder of the previous posts that you linked to in your last post, above.

Do you mean the high EM field fools the meter and the display fluctuates?  Some more details please.

Gyula:
  Well, I don't know. I get no reading, at all. Like there is nothing there. Previously I was getting about 50mA's draw, or so.
  When I test the current at the input with the meter now, set at 2000mA setting, the bulbs don't light and I get NO reading.   So, maybe yes, it may be the HV feed back to the battery, or the meter itself in contact with the circuit, which may be messing with the circuit's normal operation.
   In any case, the main thing for me is obtaining some use able light from this crystal oscillator. NOT do easy to do so far, as it's running on flea power.  But, the diode loop works, along with the AC series diodes (LEDs), as the Doc had mentioned. 
   My last unloaded reading at the bulbs, (without the load on) was 72v. So, I'm getting there, need at least 100 -150v to see some real light output. My last video had about 50 leds being partiallly lit, with just 5 and 5 diodes on a single loop.

   So, I'm remodeling the oscillator now.  Adding more diodes, adding a trim pot for the base circuit, removing unneeded parts, etz... 
   
   Anyone else building something up these days? It's getting pretty lonely here now.

   I guess the Doc is still waiting for the weather to cool... to put those two rods in the ground.

Hi Nick,

The  'no reading at all'  means the meter may have a fuse inside that became an open circuit?  You need to open the meter and check it.   Perhaps the measuring leads have a contact issue?  Use another meter in the Ohm range if you happen to have another meter to check the leads.  With this other meter you can check this meter in question too: just measure Ohms across the input of the Ampermeter set to the 2000 mA position (or lower). You should find around 1 Ohm and less resistance shown on the other meter.  Rotate the range switch a few times to check the internal contacts of the switch too.  If this DMM has a 10 or 20 A current range, then check it too,  it usually has a separate input with respect to the Common input.  You can check the oscillator current in this 10 A or 20 A range, just to see whether the 2000 mA range is what is wrong (most likely due to the open fuse).

When you use this meter in question to check the input current and the LEDs remain dark, then there can be no HV field around because the oscillator cannot work, right?  It iis the meter and the connecting leads and the contacting points that must be faulty.

   Gyula:   Yes, my meter is bad. The fuse was blown, and besides that, there's no amp readings now.  Another one bites the dust...
   It's not the first one that dies this way. Once the voltages from the HV get high enough, that is the usual results.

   I'm reworking the crystal oscillator, and I'm almost done. I got the 8 and 8 diodes on a single loop now. Trim pot on the base circuit, also, and some rewiring as well.
   I'll get another meter soon as I can, but it may be a while. 
   Thanks for the help.
