I also want to show some photos of the now finnished Trio 9R69D, restored to better than new specifications. Only 1 electrolytic capacitor was bad, so all capacitors and components seen on top of the PC-boards are original.
The large grey electrolytic 3x40uF in the background was also found to be ok and left original.

The only difference you can see with the cover off, is the ventilated shielding cans on 2 tubes and cooling shielding cans on the oscillator and on the stabilizer tube OA2 behind the main tuning capacitor.
That tube was also moved to the empty hole for the calibrator tube socket, further away from the main tuning capacitor, not to heat it up.

Also one knob on the BFO capacitor was missing, but I found a similar to the antenna trimmer knob and it fits quite good and looks even better than the bigger original knob.

On the last picture is on the restored and calibrated military signal generator, built in Sweden by CEMEK in1958, which was used for all alignments of the Trio.
