Rotel RB-5000
Not much is documented about the Rotel RB-5000 power amplifier. What the record shows comes mostly from a review in HiFI-Stereo (September 1978, p.50-52) and a classified listing in Audio (July 1978, p.112).
The HiFI-Stereo review tested the RB-5000 alongside the RB-6000 and called it an exceptionally powerful amplifier. The magazine said its electrical performance was beyond what the available test equipment could measure with any accuracy. The amp had protective circuits that shut it down under overload. To restore operation you had to cycle the power off and on. It also had a power limiter.
The reviewer noted that the RB-5000 was styled for home use, but its size, weight, cost, and power consumption made it impractical for almost all home installations. That suggests it was aimed at serious enthusiasts with dedicated listening spaces. A test chart in the same review measured both the RB-5000 and RB-6000, referencing 500W as a test power level and showing total harmonic distortion at 1 kHz. The exact rated power output for the RB-5000 is not clearly stated in the surviving fragments.
A July 1978 classified ad in Audio listed the RB-5000 among Rotel products available for immediate delivery, alongside the RX-1603, RX-1203, RA-1412, RA-1312, and RI-1024. That confirms it was part of Rotel's late-1970s lineup.
Beyond these period sources, almost nothing else is recorded. No service manual, schematic, or specifications sheet has surfaced in the usual archives.
