Rotel is over 50 years old these days. That's over half a lifetime, a few generations and a couple of average marriages. In that time, we've released a lot, and a lot of our older components are still highly sought after on the used electronics market.
If you have time to wait and take care of your equipment, a flagship pre/power combo bought today might be worth more in thirty to forty years (provided you're willing to sell it). The famous RB-5000 and RC-5000 pre/power combo - one of our industry-leading products of the late 70s - is one such sought after duo.
With all the bells and whistles, the duo had a combined weight of 53 Kg, and the RB-5000 had a monstrous output of 500W per channel (20Hz-20kHz, both channels driven). Aptly nicknamed 'the POWER amp' and 'the CONTROL amp' these are two products to not pass up at a garage sale.
Of course, let's not forget, we also made tape decks... and they were awesome.
