This one is a monster! It’s the Rotel RX-1603 and is the biggest receiver they ever made. It earns its way into the Monster Receiver hall of fame by churning out 180 watts per channel into 8 ohms. It was made in Japan and would set you back a hefty $1100 when it hit the market in 1976. You would probably have to have someone help you get it to your car because it weighs in at a plump 73 pounds!
It has a beautiful white/amber glow that emanates from the dial face, FM tuning meter and signal strength meter. I wouldn’t necessarily call the receiver aesthetically pleasing because it has somewhat of a robotic look to it and the alternating knobs and switches give it a mechanical Morse Code look.
The Rotel RX-1603 didn’t just perform at high levels it was also built with exacting standards. It featured top of the line Sanken 2SC1586 output transistors that were hand picked and hand tested. It has 22,000 x 80v power capacitors that are as big as beer cans as well as a specially designed toroidal transformer made just for the RX-1603.
Another interesting feature of the RX-1603 is that it can be separated into two units, much like the Sansui G-33000, so that it will fit in more confined spaces. At 60cm wide, 18 cm high and 55 cm deep it won’t fit in most cabinets or shelf spaces. But, with the special RK-100 separation kit you can break down the unit into two pieces and stack them. It saves about 27 cm in depth. Of course, nowadays that kit is very hard to come by.
Because the unit can be split into two pieces the designers located most of the inputs and outputs at an angle on top back of the receiver itself. The speaker outputs are located on the back of the amp section. There are outputs for three sets of speakers.
While the Rotel name may not be as well know as Pioneer or Sansui it has held its own with regards to price. Both the Pioneer SX-1250 and the Rotel RX-1603 run about the same price when fully restored. So, if you want to veer a little bit away from the mainstream, and want monster receiver power, then the Rotel RX-1603 just might be the receiver for you.
