I found this on the car boot sale this morning. AVO Mk1. The price was £75, but I pointed out there was no valve-holder panel. Eventually, I got the price down to £40, and at that stage, asked if it worked. "Don't know, pot luck" was the reply. I said I may give £35 for it for spares, and was told no deal. So I said I would think about it as I walked round town. I had hardly got ten feet away, when they relented and I got it for £35.
When I got it home, I had a dreadful job getting it open and even managed to damage the case edges in doing so. Once I looked inside, it was pretty obvious it is a write off. The mA/V wire-wound pot is physically damaged beyond repair, and I don't suppose spares are available.
The good news is that the meter movement is OK, so I have a spare for my working AVO Mk1. Also, of greater importance to me is that the tapped heater transformer is OK and that must be a very expensive piece of kit. The rest of it doesn't seem to be in too bad condition, and I am quite happy with the purchase!
