[The Philpott]

Thanks John, that's quite a smart looking thing. I'm not sure if the yellow legends on the front are original, or whether they should be ivory. It's basically a tweak of the Model 8 and 9 design, carrying Model 8 (english!) legends but Model 9 type (100/30) scale.

Certain components are potted in resin against humid environments. Mainly discrete components in there at this stage rather than windings of resistance wire so reliability quite good.

Richardsradios is 'the' website reference point for different versions of the avometer.

Meters that are damaged or killed are usually the victim of electrical misuse, a drop from height, or corrosion from old batteries.

The inside of the meter is quite cramped, some repairs can be awkward to carry out. A meter that has no corrosion, a healthy movement and unworn leaf switches is something that should carry on working for a very long time.
