*UPDATED*
The CA-W20 was the top of the line 3-piece boombox fromAiwa. It is 63cm long and was introduced in 1983 or 1984.
It features a dual deck with programmable auto-dubbing. The 10 buttons between the decks allow you to select the sequence of the songs you want to dub. Wow and flutter is very low (0.04% WRMS).
Frequency response is very good (30 to 16,000 Hz when using Metal tape). The woofers are 12cm and the tweeters are 5cm. And there is a large passive radiator underneath the tape decks. It is powered by air coming from ports in the detachable speakers. If the speakers are detached, then the passive radiator will not function.
This has been professionally Refurbished by Lightning Repairs in Manchester. I have an invoice and I will send a photo of it upon request. It took a long time to find parts but now it fully works, both cassette decks work and all speakers are loud (very loud) clear and even.
The only things that could not be made to work are the 'pause' functions on the cassettes, it just mutes the audio but the tape keeps playing. The cassette doors do not have 'soft eject' these required parts that were unobtainable. The memory functions are hit and miss also.
It is exceptionally rare and currently the only one listed on ebay in the UK. The only negative is the slight cosmetic mark (pictured) that is on top of tge unit. But i believe this could be painted over by someone who knows what they are doing.
