1969 Geloso G.1/1040 40W EL34 Tube Amp

Here’s another nice vintage Geloso tube amp, though already dating from 1969.  With two EL34 tubes, it sports a nice 40W of output power.

Unfortunately, it’s not working, and the reason is clear from these voltages: there’s only coming 245-260V off the solid state rectifier.

With the tubes removed, the voltages are up to scratch: 360V
