Best thing for an Avo that.
Together with the 8060A I got an AVO Multiminor and a Hung Chang toy. The Hung Chang is never coming close to being used; it's down right dangerous. The Multiminor looks superficially OK, but is as of yet untested; my plan is to assess it this weekend. In the repair queue I've also got a Model 7 Avometer that looks OK from the outside but is somehow broken; no reaction on any range is detected.
None of these will be turned into a lamp.
As far as the telephone; I've got an Asterisk PABX at home where one of my Grandstream ATAs has support for pulse dialling, including the Swedish system where -- properly -- 0 is less than 1. So, a rotary phone is not useless here; I've got one by the bench and one in the garage proper. The garage one is a BC560, which is a name collision with the transistor. The phone was first.
That's always the problem with Avos. They always seem to be broken. You can tell by the high price a working one commands ![Laughing :-DD](https://www.eevblog.com/forum/Smileys/default/smiley_laughing.gif.pagespeed.ce._hfWAz_QHO.gif)
Rubbish, AVO's can still be had for not a lot of cash, working OK as well and providing the seller understands them, they can be transported reasonably safely. If the meter does not have an official "OFF" position on the switches, then select DC and 50uA ranges on the 2 switches and a shorting link between -&+ terminals and your fine. The meter will be well damped to cope with most jolts which cause the needle to swing violently. I have purchased 4 Model 8 AVO's, all arrived fine as a result of setting them in their transit modes, 3 are in use today and the 4th was fucked internally by some bloody gorilla but it was really cheap and a source of spares.
One thing with all meters is that the seller must pack them pretty well because of the meter movement is pretty delicate by its very nature. I've brought loads of analogue meters over the years, including some Heathkit VVM's and ever had 1 completely buggered movement, a Heathkit.
The most recent one was that TMK500 which had no way of damping the meter due to the missing switch contact, and it arrived OK without much protection, a single wrap of bubble wrap,

and that movement was what I would consider to be the most delicate of them all as it was a "Taut Band" suspension system for the needle.
