Thought I would share where I was at with this so far. Been studying the DVD video close, and what I came up for the beta multiplier stage so far is different than what I have been seeing everywhere else. This is what I am seeing over all on the board though, two linear reg packages, one controlling the amp and beta multiplier, and the other is just the power supply (probably 5v) for the comparator IC and LEDs which is powered off the charging battery. In my drawing, c2 is small and c3 is large, forming a voltage divider(but also it is another filter stage) to start the beta multiplier feeding the regulator when the SG is running. My thought is it just barely turns on the multiplier, and the linear regulator feedback punches it when needed. This isn't tested yet, as I haven't figured out all of the component values to start with yet :





Also, please note, the only way you will know if you have it all figured out, is if you test it with a radiant input and only see almost perfect dc on the output, with little to no ripple.

hey everyone,
i just built the battery monitor part of the linear reg amp, ignore the marked + and - on the board because i did, i connected it up and popped the ic on reverse polarity straight up lol luckily for me i had a ic holder in so i could easily change it out.
the circuit isnt my own i found it on the net and works like the bedini video, i set the red led to be on by itself up until 14.7 ish and then the green to turn on at that same voltage and up, the red goes out and the green comes on and if the circuit is left on you can watch the led's swap back again as it goes back down and around 14.7v they swap back. i think in bedini's awesome dvd i bought there was only 1 pot to move to change this voltage changeover point but it does the same job and without watching the dvd i probably wouldnt have made the circuit so a shout out for bedini u are awesome and also the circuit online i posted because its not mine im sure that person should get credit for the circuit too.
i tried another circuit with only one op amp and the 2x leds were against each other but i couldnt get the leds to swap over they were both on for some reason, looking back i probably should have had a 680ohm resistor in line with each of them and it might have worked, i have the board still ill find it and post it too with the circuit i made it from to see where i went wrong

Nice work pjreed01
if you watch Mr Bedini video he only used one op amp. what we were doing way back then was trying to come up with how John did it. Nitesh added some more bells and whistles but tried to follow how John did it.
I bread boarded the comparator part on the charge state of the battery.
It does have an issue in the Schematic as drawn.
it works fine if you don't connect it to the VR (adjusting the Regulators) but now what to do with the VR. Maybe a resistor to ground?
Or go with your idea and use 2 op amps

Hello everyone,
I wanted to ask a question,.
I replicated Nitesh Schema,exactly this - as far I can see it seem's to work, i use a 30V 5A power supply, to test the circuit and tune/balance the voltages,but as I understand,LEDs should't both light up while the voltage on the battery does not reach (let's say 15v) that we determine with the RV1,but my two LEDs are constant light, independent of the battery voltage 12v or 16v,no matter how I adjust RV1, both two LEDs are always bright...
My question is
Perhaps I misunderstood something, maybe LEDs must light up simultaneously, or I miss something, please help me if you can
THANKS
excuse my bad English

Hello Tjjusten I had purchased the DVD 6 weeks before I made my fist post on this thread, and I had also purchased, the "Linear Amp Regulator" Too.

That's awesome. i must say i was a lil disappointed when i bought the DVD. the Real content of the DC linear Amp was left as a "black box".

[Nityesh Schnaderbeck]

@Nityesh Schnaderbeck, that would be great. YOur understanding of Electronics is very deep. But do purchase the DVD.

Linear Amp build

Greetings:

I have an 'up and running' version of the Linear Current Amplifier.

A 2n3055 was used to power it on and two MJL21194s were used as Q1 & Q2, while a NTE37 is on the output.

The whole thing is powered by a Kodak printer power supply providing 36VDC @ 2100 mA.

This thing is pretty neat!

I appreciate you folks sharing this.

Right now, I'm working on a scaled up build using a transformer from a UPS, 60 Amp bridge from somewhere, a 51000 mFd cap, and several MJLs of both flavors.

Pics attached.

Someone requested if I could post my Previous circuit designs of the "linear Amp Regulator" That I designed before I came to this forum. It may help someone to get some circuit design ideas.

But now I have a new circuit that I will post soon.

The Previous Circuits, before I came here

But now I have a new circuit that I will post soon.

[Nityesh Schnaderbeck]

Regulator Phase Splitter Amp Ver6, Sounds awasome now

I had a look at the internal schematic of the LM337 and I saw my big mistake with all the previous versions of the "Regulator Phase Splitter Amp"

Both Lm317 and LM337 have NPN power transistors inside.

Inside the LM317 the emitter of the internal NPN power transistor is connected to pin2 (+Vout)
Inside the LM337 the emitter of the internal NPN power transistor is connected to pin2 (-Vin)

So the following circuit has the internal NPN power transistors from both regulators connected as "emitter followers"

This new circuit has the true high fidelity sounds, nice bass and nice treble, and is louder than the previous versions of this circuit.



note: Both R2 and R3 are 3.9K (looks like 39K on the picture)

"Ecancanvas" you will love the sound of this amp now, very nice.

[Nityesh Schnaderbeck]

Complimentary Regulator Phase Splitter Ver.5 with offset adjust

Here is the same circuit with an offset adjustment, I believe John Bedini had a similar or same offset adjustment on his "Linear Amp Regulator"



Note: R2 and R3 are 3.3K (on the picture it looks like 33K)

Reasons why I think that these regulators are used as like an audio phase splitter.

In the posts I read John Bedini, says that the regulators have to be matched. If the regulators were used as static voltage references, then they would be not need to be matched, just simply adjust the opposite voltages the same.
But as a phase splitter, the more identical the plus and minus regulators are in characteristics, the more accurately it will phase split the signal.

John Bedini is also talking about regulators as class A amplifiers, and that the industry standard had taken away the control pin. But if you bias it correctly, these regulators can be used as low power Class "A" amplifiers.

[Nityesh Schnaderbeck]

Regulator Phase Splitter Amp Ver4

This design can be simplified even more, and this also works. Looking at the LM317 schematic, I see that the output pin is connected to the emitter of the internal power transistor. So this amp is using an emitter follower as the output stage. Because of this, the two 47ohm resistors are load resistors and the feedback resistors. Here is the simplified schematic, and it even works.



"Ecancanvas" you were right once again, without knowing it, in this circuit the two 47ohm resistors are feedback resistors, Congratulations, good on you and thankyou

Some notes: If you drive it too much it will distort, too much bass will make it distort, if the load resistors are incorrect for the speaker load it will distort, and if R1 and R2 resistor values are too high or too low it will distort. But when you get the bias right it sounds good. And this amp is not very loud. The output capacity can be increased by making the two 47ohm resistors a lower value, then the regulators will need a heat sink, but this is not the point of this experiment since, this amp will not be delivering any power anyway once it is in the "Linear Amp Regulator" circuit.

[Nityesh Schnaderbeck]

Regulator Phase Splitter Amp Ver3

I have discovered that this circuit works without the diodes.



It seems to work better without the input capacitor, it also seems to work without the output capacitor. I have the 470uF cap in place, just an extra measure to make sure DC does not flow through the speaker.

The ratio of resistors values in this circuit seem to give the best sound.

[Ecancanvas]

Nityesh, Its free but they restrict the times you can use it. They only want you using it in evening and not at work. the program is called Yenka its down side is i have not been able to find voltage regulators, but for working out how the circuit is working and the amps and voltage its pretty good
