On the nostalgia make & model list under SUPREME way down at the bottom, there is some odd-ball piece of a thing called a DIAGNOMETER! I have never heard of these. What are they & what do they do???? Are they still used & if so are they under a different name/title? Hope some of "
all you old buffs" can help me out? Maybe these things were out when I was still in diapers & if theyr'e not in existance why were they discontinued?

Take a look here: http://www.supremeinstruments.org/diagnometers.htm

These things aren't around any more for the same reason you won't find a dwell meter in an auto repair garage- they aren't relevant to present technology any more.

:::That's a good answer----BUT what did they do? that's the main question. Thanks

The site that I posted (http://www.supremeinstruments.org/diagnometers.htm)
pretty much describes what they did. To summarize, these testers attempted to be a "single tool for diagnosing all radio faults". Looks like various models had different capabilities as it occurred to the tester maker (Supreme Instruments) that additional test features would be helpful.

I have no idea how useful these things were, but I suspect that it was somewhat like most "all in one" tools: you end up using 10% of the thing's capability for 90% of your work. So, from that standpoint it was probably a better capital investment to buy general purpose test equipment (meters, tube testers, scopes, etc.) than a package like this.

The idea was to do as much as possible in the customer's home. Radios were expensive items and people didn't like to have them "taken to the shop" where they couldn't see what was happening.

A set of instruments that could exercise all the radio circuits was(is) a handy item. Some test sets had extender sockets that allowed tubes to be plugged into the set while all the pins voltages were monitored on separate meters.

All these things had their day.

:Thanks for the reply, sounds like an all around tester. Never heard of one before, before my time. Yeh, right.
