TESORO GOLDEN SABRE

Maybe you can make a dual beam adapter. Allows you to use a single channel oscilloscope to display two signals simultaneously for comparison. Here's the link to one such circuit.

I'm sure there are other similar circuits out there. It's not the best, but if you just want to compare the phase difference and null for balancing, it should suffice. You may need a preamp for the RX signal for the above circuit.

Thanks,guys
is it possible?
the coil should be two identical circles,not two D
like the picture I put

Do you reckon the dual beam adapter would work as per the schematic

Why,? Have you seen something on the schematic that looks suspect? It's essentially a chopping circuit. I only had a cursory look but maybe I'll check it out again in greater detail. In 1974, a dual channel scope would have been quite expensive.

You can have 2 D's or 2 circles or even 2 squares if you wish. The principle is the same. Balancing is achieved by overlap method.
In the concentric coplanar type coil, balancing is achieved by means of a feedback coil commonly referred to as a buck coil
So there are essentially two kinds of coils based on how the nulling of the RX coil with respect to the TX coil is achieved. Namely 1 overlap method, and 2 feedback method.

There is also a coil known as an Omega coil. But it is still a coil using overlap method for nulling.

Just because you can make any shape doesn't mean that you should. The optimum or best shape for overlap method of coil is the soft 2D shape. I recommend you make this coil for tgsl.

sorry Delta Banner i must reminder that Tesoro design coils were NEVER '2 D's or 2 circles or even 2 squares'.
they were always classic planar. Tesoro was always kinda conservative. NO DATA on 2D coils, NOT EXISTING, people has to calculate THEMSELVES those data
and check themselves.

My dear KT315, it is not for you to interpret my reply to the other member, but for him, in order that he may grasp on the fundamentals and basics of coil design.
If I was speaking to you, I would have said something quite different, like for example, take those two circles and put them around your neck.. and look for nearest ac wall plug.
Of course I'm only joking.

I have only had a cursory look also, not studied in detail, it would be handy for the guys with single channel, could be worth a go at.

Maybe I give the circuit a run on ltspice. The plot of the output waveform should reveal whether the circuit is feasible. If it is, then maybe I'll go looking for a single channel dinosaur, just for fun.
I need to read through the article carefully to see how this thing is supposed to work.

we mean the (THE) filters in tesoro schematic, at very first. they sure had been calculated/made under a coil used.
just because the coil is always in moving above ground with the certain given speed.
if not - a niwbie gets a trouble, no depth! WHO have to tell that 'to the other member'?
Vaniuschka from Novosobirsk city or good englishspeaking senior from USA??

Or Vytautas from Zarasais)))

The parameters of the tesoro coils are well known.
Here's a tesoro stock widescan coil (2D) on the end of a tesoro royal sabre. Same filtering as the golden sabre. These coils came in two sizes, 8 inch and 11 inch.

Does this scope help me????

Here is another scope beam switching unit circuit. This one uses only transistors, easy to construct and should do the business.
