Level Measuring Set 30A - Oscillator 132A ??

Then they brought out the VTR103:

I hadn't realised that before, Lawrence - or I'd forgotten - but I did say: 'Look at just about any early transistor radio circuit' , not every circuit. I was aware of some exceptions but couldn't recall any of them off hand.

Doesn't that VTR103 circuit look odd, with everything hanging off the earth rail like that?

I would agree, Andy, that germanium transistors were mostly forgotten by 1976 but, if the design worked and the units were produced over a span of several years there would be no reason to change it. These units would only be produced in small number so were hardly likely to have any impact on remaining germanium stock levels.

By the way, are you familiar with the geranium diode?
