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. Peter Wieck Wyncote, PA |

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. -- Mike Schultz "Peter Wieck" wrote in message oups.com... firedome wrote: Please eMail direct to: dieselpug"at"stny.rr.com Excellent Hickok 6000a tube tester, calibrated, good roll chart... $400 The 6000A is the "other" version of the 6000, and therefore came with the more recent sockets.

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. |
