Restored June 2026 ****Shipping No P.O. Boxes or meet ups****Description:The reverberation amplifier is one of Pioneer's unique products.Unlike ordinary high fidelity systems that use single scatter systems, the SR-202 employs a double scatter system involving the merging and blending of two channels in a complex composite sound.The direct signals from the pick-up that have been fed through the preamplifier, and the reverberation signals, which are comprised of the signals of the opposite channels to which reverberation effects have been added, are merged and blended to result in a composite sound that includes echoes and reflected sounds.Two time delay circuits eliminate any peaks or dips in reverberation so what you hear is absolutely stable and has tremendous depth and brilliance.The SR-202 reverberation amplifier can be used to increase the naturalness of your own recorded voice, radio broadcasts, records or tapes.It can be coupled with your own system's amplifier (with tape monitor jacks) in various ways, to provide reverberation effects to the speakers only, or to just the recorded sounds, or both together.You can even control two tape recorders at the same time by switch operation for simultaneous recording, recording with reverberation, playback etc.In fact you can connect the SR-202 in practically any way you like for the effects you want. The system can be converted back to normal operation any time with the flip of just one switch.SpecificationsInput level: 200mV (3V maximum)Output voltage: 330mVHarmonic distortion: 0.2%Frequency response: 20Hz to 35kHzSignal to noise ratio: 65dBReverberation time: 1.9 to 3.2sDimensions: 300 x 115 x 250mmWeight: 4.0kgSemiconductors: 11 x transistors, 2 x diodes
US$225 looks fair to slightly attractive versus the recent used market, sitting right on the median and just under the upper half of comparable asking prices.
That makes this a sensible buy if the unit is complete and presents cleanly. This kind of Pioneer gear tends to appeal to enthusiasts who want solid vintage build and straightforward everyday usefulness, so the value here is mainly in getting an example that’s well cared for rather than chasing a deep discount. At this price, the smart move is to confirm basic functionality, cosmetic condition, and whether any original parts or accessories are included.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Pioneer traces its roots to 1937 in Tokyo, Japan, when founder Nozomu Matsumoto, inspired by the thrill of imported hi-fi speakers, developed the A-8 dynamic speaker and launched a radio and speaker repair shop. The business formalized as Fukuin Shokai Denki Seisakusho in 1938, evolving into Pioneer Corporation and embodying Matsumoto's philosophy of "Move the Heart and Touch the Soul" through audio innovation.
The brand excels across diverse hi-fi categories, pioneering Japan's first headphones in 1960 with the SE-1 and the world's first component-based stereo system in 1965 via the PSC-5A. Pioneer's portfolio spans amplifiers, speakers, turntables, and DACs, alongside landmark car audio advancements like the 1975 Supertuner-equipped stereo and the 1986 in-car CD player, blending home and automotive excellence.
Today, Pioneer holds a commanding mid-to-high-tier position in the market, revered for reliable, performance-driven gear that balances premium quality with accessibility. Its vintage components attract collectors, while current offerings appeal to discerning buyers seeking robust, innovative sound reproduction without boutique excess.
