Testing the TK Tar Baby

She is a reptile.

Good stuff MH!  It is delightful to see and hear those
old tunes which were popular when I was a deck seaman
aboard ship home ported in the San Francisco Bay area.

Reptile aye.

You guys may win her over yet with your playful banter.

It is quite obvious that the gang here are enamored of her.

1.  to fill or inflame with love (usually used in the passive
followed by of or sometimes with); to be enamored of a
certain lady; a brilliant woman with whom he became
enamored.

2.  to charm or captivate.

Yeah, sure ... like a favorite inflamed pimple, or an inflamed rotten tooth. Feels sort of good to  poke it, but when it's finally popped or extracted, the relief is even more palpable.

Bear in mind that under this "schematic" the source leg of Q2 would be DISCONNECTED. This statement she made while describing the proposed test.

But that source leg Q2 needs to be attached to the function generator's terminal. That's for the test. The statement she made immediately subsequently, on being presented with .99's drawing of what he thinks she might have been describing in the first proposal.

Connected, AND disconnected. That will be some test all right, with the RED FG lead (called "probe" by her for some reason) connected to the battery negative, the BLACK FG lead connected AND disconnected simultaneously to the source leg of Q2... and where are the oscilloscope probes and their "terminals" going to be connected?

Can we be allowed to see your schematic, .99? Because I now have no idea at all what she is proposing, other than it seems a lot more complicated than simply RUNNING THE CIRCUIT AS DESIGNED, and scoping a CVR in series with one or the other of the FG's output leads.

[TinselKoala]

OK, from going through the statements carefully and drawing what I think she means on a schematic with white-out, red and black markers.... it looks like what she winds up with after the second statement is simply switching the RED and the BLACK alligator clips and disconnecting Q1 source at the transistor.

Am I following this correctly, PW and .99?

Is the diagram below anything like what you are discussing?

[TinselKoala]

This constant reference of hers to the Function Generator's "terminal" and "probe" disturbs me greatly.

Is it possible..... please tell me it isn't so...... that she has used, for some trials, an _oscilloscope probe_ , likely attenuated, for the FG's output connection at some point? After all... both the FG's output patch cord and the scope probes have the same BNC male connector on the instrument end......

So maybe, for convenience, she uses a BNC T-connector at the scope. So the FG's output goes to the T with a patch cord, which is on the scope  channel input. This eliminates one probe at the circuit, since you are just monitoring the FG's output as the "gate" signal anyway. Then you can use a scope probe from the other side of the T to connect both the scope and the FG to the circuit with one cable !! Briilliant !!

Please tell me it isn't so.
