Philips 22AH777 receiver, manufactured in 1978 in Sweden. Built like a Volvo. It weighs unexpectedly heavy, due to massive heatsinks on the side and thick aluminium front panel. Nice details: it can serve 2 speaker groups AND can drive MFB (Motional Feedback) loudspeakers. Also, there are 5 FM presets, which can be chosen with the function switch on the right. The unit produces a clean and powerful sound (2x55W into 4 Ohms), which easily can fill a large living room. New LED bulbs were installed, which look very cool on this feature rich receiver. This is a relatively rare and underrated beast.
