Pioneer SR-202 Vintage 1970's Reverberation Amplifier - Spring Reverb

Personally cleaned & tested, great working condition.

Tom Elmhirst interviewed when about mixing Rolling In The Deep by Adele (Sound On Sound, Sept 2011):

“…the Pioneer on 55‑56 is an old ‘70s‑’80s spring reverb that was made for the domestic market.” …and on mixing Mark Ronson’s Record Collection album (Electronic Musician Sept 2010): “I used a lot of external reverbs: a Fairchild 670, old spring reverbs, and a couple 1970s Pioneer Reverberation Amplifier Model SR-202s. They’re old home hi-fi units; they’re not normal! I am not a fan of digital reverb, so I have a few springs I really like… Spring reverb was a big part of the Winehouse record, and it’s in Mark’s sound as well. I use two or three different springs on a track and even on the vocal.”

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.
