Guys,
my LOPTs are television LOPTs, thus they would have no internal capacitor.
i am referring to this post from Maxolous here:
https://www.overunityresearch.com/index.php?topic=4219.msg110508#msg110508 2nd video:
https://www.youtube.com/watch?v=kK5pOSgyvaw where can be seen (like at 1:27) this view of a LOPT:
As can be seen, this is a modern LOPT like i use and which is internally connected like this:
So no capacitor on the output because as i understand it, the CRT itself serves as a big capacitor.
But in this Ruslan device setup it looks to me that nothing is connected to the thick red output lead (going inside the grenade ending at the opposite site).
I retested with my same LOPT, but varied the duty cycle from the 50% to 1%, but the DC stayed, only got less en less.
Then i used another LOPT (bigger) and also used its internal primary but with the same result (7kV DC at 3.5V input)
Then i wound a 6 turn external primary (like the white one in the Ruslan device) and used this to switch it, but again with the same result, 6,8KV DC at 3.5V input, see picture and screenshot:
Also here when reducing the input duty cycle from 50% to 1% only reduces the DC level to almost zero
When putting the scope in AC coupling, i see this ripple on the 6.8KV DC:
So once again, according to my tests, such modern LOPT produces a static DC on its output (WHEN LOADED WITH A HV PROBE ONLY), so no sharp pulses are present, but once again, perhaps they somehow pulse this static DC / field.
