Dimensions and weight: 18 cm high, 38 cm wide, 25 cm deep. Weight: 9.5 kg
Power requirements: 117 VAC, 50 W.
When I tested the receiver after purchase it basically worked, but had a lot of audio distortion. This was reduced by replacing a leaky C23 (detected because of +0.8 V on the 6AQ5A grid). Some distortion is still present especially on strong stations. I should probably check the capacitors on the AVC line for leaks since the AVC does not look to work too well.
Alignment history (the calibration keeps moving):
My receiver has a power-line leak problem (mild but annoying shock when touching the chassis). This is enough to knock off the house differential switch if the chassis is grounded. I replaced C28 without improvement. Reversing the insertion of the power plug reduces/suppresses the effect. To find the correct orientation touch the ungrounded chassis with a neon tester: it's OK when the lamp is off.

|Rear view of the chassis. From the left: multipin socket/plug for remote control when used with a transmitter; antenna binding posts (balanced and unbalanced); S-Meter zero adjust; audio output terminal strip; fuse. The mechanical construction is robust. Clamps are used to keep tubes in place.|
|Bottom view of the chassis. The coil pack and the band switch are in the middle, with the mica trimmers well visible. On the bottom right are the main power transformer and the transformer for the mixer and oscillator filaments (always on). I suggest to suppress this feature to spare the life of filaments by rewiring its primary in parallel with the main transformer's primary.|
