Wheeee.....

A typical stereo phono cartridge of any ilk has four (4) wires coming out
of it. Some (very) cheap devices have only three, sharing the ground
between the channels, but I have not seen one of those for over 30 years.

Oops, I was having a brain fart. Yep, these are STEREO cartridges. They
need FOUR wires (or at least 3 if they share the ground).

Whoooo Boy! I can think of no reason whatsoever that one should ever use a VTVM in these modern times. Sure, loading a Zenith TransOceanic while performing an alignment via a VTVM makes some of the things go 'by the book', but using a regular high-quality VOM is just fine.

A VTVM has a 1 megohm resistor right at the DC probe tip to isolate
the cable capacitance from the circuit being tested. Of course YOU would
never think of using the right equipment.

You never do any precision work, so any old crap meter is fine, for
you.

You don't care about detuning an RF or IF stage, or shifting the
L.O.way off frequency.

Mpfffff...

No, I do not do precision work, which, in point-of-fact is probably the case as the typical Zenith or Hallicrafters or Tesla or SNR radio is not a precision instrument. But, they do just fine aligning with a Fluke meter ILO a VTVM.

Nor, of course does Old School. And, given his posts, is likely defeated by anything more complex than a rubber spoon.

You're trolling, as always.
