I have a working (well it was working last time I used it) Marantz SQA-2B decoder. It was bought in 1975 to replace an SQA-2 but the 4140 amp with SQA-2 was stolen before I could change it.
I soldered the device into another non-Marantz quad circuit (I have the pin-outs) and used it - occasionally - for years without problem. I now have another SQ decoder so it is no longer required.
I have since desoldered it and cleaned up the contacts. It is thus not in new condition but it should work fine back in a Marantz amplifier or tuner with quad socket underneath.
The SQA-2B has a known ideosyncracy in that the rear signals are somewhat lower in amplitude than the front signals compared to SQA-2 outputs. This can be (and was) easily balanced by use of the front/back fader on the Marantz amp.
The surround logic in the SQA-2B is fine, however (since I last used it some years ago).
Note that my motive for posting this is not to sell it - it takes very little space - but to give some deserving Marantz quad enthusiast who just needs an SQA-2B an opportunity to make his system complete. Price can be easily negotiated.
Is anyone interested in it, as-is? I live in South Africa so postage may be a factor but shouldn't be too high.
