Deep cleaning of my beloved AIWA CSD-SR6, a beautiful beast

I received at home my old beloved boombox that I’ve had when I was a teen: the AIWA CSD-SR6. I bought this boombox back in 1991, just before I started studying in the university. I’ve had a nice Hitachi 3DS75 and I really was searching for a big -but still portable- improvement. And I found this impressive piece for 56.000 pesetas (spanish coin back then) which is around $750 of 2014 US dollars…

This model is the best boombox I’ve ever seen (and listened to) that could be bought outside Japan. However, there were a few high level competitors that could surpass it: his biggest ‘brother’, the awesome CSD-SR8, the Panasonic RX-DT9 (I wrote about both in this article) or the massive SANYO PH-WCD950.

It has a huge lot of features that represent the one of the most advanced (if not the most) boombox made in the 90′s (outside Japan, again). It includes:

  • Double quick autoreverse deck, metal compatible, with rotating heads.
  • 10.000cc resonance capacity speakers each with bass reflex ducts (the biggest resonance capacity seen in a boombox).
  • 15W DIN power
  • Two knobs for bass and treble.
  • Dolby B (for recording also).
  • Syncronized computerized CD recording to tape (does ALL: analyze CD, adjust recording level, records two sides, erases cropped songs at the end of each side…)
  • PLL radio with 30 presets.
  • full wireless remote with so many functions.
  • Motorized volume knob

… and many other…

This beauty was at my father’s home for many years, collecting dust far from me. This is how it looked one year ago when I pulled it out of the closet:

Not bad, but if you look close, you will notice the dust:

But look inside the decks:

I managed to take back home after so many years and decided to do a deep cleaning of it, so it will be part of my collection again. I fully dissasembled it. After some brief clean, this is how it looked:

in a closer look:

So, I removed every cable and electronic board and put it in the shower and started to deep clean it. It’s definitely a rare shot to see :

Once cleaned and dryed, started to put things. First, the internal power supply:

It’s curious to see the internal ribs to make more rigid the speaker box:

Then, I mounted the speakers:

Here is the internal electro-mechanic block, with the two decks after cleaning and demagnetizing:

So finally, I could assemble all and adjust the azimuth to finish it. Now, this is how it looks:

AIWA CSD-SR6 02

Nice, huh?

Of course, both grids as well as speakers were carefully cleaned too, to take them back to the clean original black look:

Look at the front control panel:

The top side is very clean, with only the CD, volume and tone controls:

AIWA CSD-SR6 08

It’s curious that it has the common ‘Bass & Treble’ knobs as seen in many HI-FIs. The BASS knob goes from ‘Narrow’ to ‘Wide’:

Now the heads look completely different, and they have excellent sound!

Here you see the radio station playing:

And here’s the radio:

And here you can see its back:

And that’s all! I hope you enjoyed a lot.
