The 6000A is the "other" version of the 6000, and therefore came with
the more recent sockets. So, 7 & 9-pin miniatures, compactron (9 & 12
pin), Octal, Locktal, nuvistor, transistor & VOM. It will not test its
own 4-pin 83 mercury rectifier, for instance. It is also much more
limited than the 539-series inasmuch as it does not have variable bias,

does not have a way to test plate and filament current directly and one

must choose between which vintage tubes one is able to test (without
adaptors). So, as a general-purpose GM-type tube-tester when matching
is not a
requirement and pre-octal tubes are not used, it is an excellent
option.

Note that the 6000 option (both the 6000 and 6000A were offered at the
same time) does test pre-octal, octal, locktal and 7 & 9-pin miniatures

(also transistor & VOM), but NOT nuvistors or compactrons.

As to the price, that is between the buyer, seller and their respective

gods.

Most nice 6000A's bring between $200 and $300 on the well known auction
site.

You're right-in no way is this an alternative to the 639C (or any of the 639
series, for that matter).

It has one serious drawback that you didn't mention. Most Hickok designs
allow you to reset the line voltage while the tube is under test. This
allows you to compensate for the added load and consequential drop in all
applied voltages (filament, plate, bias, and screen).

The 6000/6000A testers specifically do not allow this.

Maybe somebody should've bought that "toy" from last week.

You can monitor the filament voltage with a voltmeter with the tube
under test and reset the line voltage.

Requiring a test-socket and a VOM. Many Hickoks had this function built
in, hence Mike's note.
