@All
Well we have less than (10) sec boards left and they can be configured either 3's or 20's and I need some vacuum tubes so am offering to trade a board for tubes (in working condition, high trans conduction).

The list of tubes I need is;
2) OD3
1) OB2
1) 5517
1) 5U4
1) 6AU5
2) 6V6
2) 12BH7
1) 12AU7
3) 12AX7

If you have any or all these and would like a sec3 or 20 send me an emal and we will work out the details. Send to stifflerscientific@embarqmail.com

Thanks

@Dr. Stiffler,
I carried out additional exploration along the lines of the circuit you posted Sunday. As can be seen in the picture I have added an additional 6 4148's and a second AV plug fed by a 22uH from the 400pF cap off of the collector. I'm wondering why we added the cap in series with the 22uH so I ran the same circuit without it. I put a wire in place of the 400pF cap. With the wire in place I notice that the ion current flow is at least 4ma higher than with the 400pF but more importantly I think is that my transistor runs much hotter, subjective, than with the cap in circuit. The transistor doesn't have to dissipate as much energy with the impedance better matched I take it? Another observation is that with the 400pF coupling the supply voltage tends to rise and current drops while with the wire the exact opposite is true.
Also keep in mind my batch of MPSA06's are lesser devices than yours. Time to order and demand better suited devices.

My fault for not checking earlier. Blasted mass production. I also found some real duds in that batch HFE's around 70 or less. You know I ran this with the transistor that came with my SEC3 and wouldn't you know I burned my damn finger again, I thought I had gotten over that,

Tuning the base coil either direction from peak causes the Ne in the "simple" branch to the left to blaze while greatly reducing the Ne intensity over in other "stacked" or "pumping" branch for lack of better terms and a personal deeper understanding of whats going on here. Yes both Ne's when tuned will burn you, but the one on the right gets you much faster, even with my lesser X-sistors. I'm running the best of my lot with HFE's at 160 to 172. Most of transistors measured out to the 125 to 145 range.

Just a little Tuesday morning fun.

Trying to learn all the time.

Best regards,

Jim

ADDED: Just thinking into it some more, it is not just impedance but the balance of CAPACITANCE in the effective impedance. We can have many different combinations of L and C that have the same resonant frequency but the C to L ratio seems quite important here. I think I'm smoking brain cells this morning so I'll drop back and reflect now.

@All,

Update for correction: My initial observation that the transistor was dissipating greater heat when the wire was in place of the capacitor was incorrect. The transistor is actually the warmest with the 400pf in circuit not the wire. I found out what made me think that also. LOL

LOL The lead of the 1Meg resistor was touching my transistor heat sink that I was of course touching to check temperature with a finger and zzzzzzt, RF burn, ouch, I just did it again when I retried the experiment a little bit ago. Ooops.

.....thanks doc! Someone has to keep me on the strait and narrow.

It was interesting just the same though.

Exploring is my absolute favorite activity and since I started building these I can say that I'm just as fascinated today as the first time I turned the power on and saw the NE light up on 1 wire. Very cool and learning even more. Dr. Stiffler so kindly pointed out the discrepency, I found the problem with what I was doing and confirmed his assessment. Good deal.

EXCELLENT!

Best regards,

Jim

Hi all

I've got an SEC 15-3 still coming in the mail, but I'd really like to play around with this stuff now. I've noticed that the SEC board doesn't seem to have the big copper pipe for the coil, but the latest driver circuit posted on Stiffler Scientific does. Apart from that coil, i've probably got everything I need to set up an SEC driver on my breadboard, so I was wondering if anybody could point me to what I should do about the coil?

@All,
Good morning everyone.

Since my mind is once again saturated I leave this for you to ponder.

This is the same circuit we have been working with. SEC exciter on a breadboard with an AV plug connected via 22uH choke to the collector of the transistor. Now the load is an 4148, green LED, NE, red LED, 4148. This was stumbled upon by accident not some stroke of insight or genius and I haven't figured out the significance yet but check it out anyway.

The progression goes like this and is documented in the photos.

4148, green LED, NE, red LED, 4148 ------------------------------------------------(circuit runs as we are used to, LED's and NE illuminated)

4148, green LED, NE, red LED(reversed polarity in the circuit), 4148-----(circuit runs almost as we are used to, red LED not illuminated)

4148, green LED(reversed polarity in the circuit), NE, red LED, 4148-----(circuit runs but nothing is illuminated)

Interchange the colored LED positions in the AV plug an do the same thing.

The green LED is connected to the CATHODE of the 1st 4148 and the red LED is connected to the ANNODE of the second 4148. So all I'm doing is flipping the LED connection in the AV plug. The phenomena is following the red LED but it is unclear to me right now as to why. I didn't want to be the only one distracted today.

Flipping the green LED kills all the illumination regardless of where it is in the circuit. Replacing the LED's with 4148's does not show the same behavior and I leave you to fool with this in your spare time

Check it out, try it out if you can, ponder if you will.

Dr. Stiffler will probably want to kick my butt for throwing a distraction like this out here. If that is the case sir I will remove this post. I just found it very interesting. It must have to do with the LED turn on voltage differences. Cool stuff and does not behave this way in a standard DC circuit with or without a 1K current limiting resistor. Man I love this.

Best regards,

Jim
