Hi all, after reading about Daniel's discovery a couple of years back and seeing that this thread is alive and well after years of information sharing I would like to tackle this project. My question is, are the JVC boomboxes offered today still the right ones? or where can I purchase my deconstruction boombox and be sure I am not making a mistake? Thanks.

I will post some mechanism, board and chipset options for you.
I have been hunting around looking for current boomboxes that use the same chipset and so far, I have only found one in Australia.
It is is fun project and one I definitely recommend.
The Sanyo laser is history ever since Sanyo offloaded the optical division, however there are numerous clones that all do the same job (pics to follow)
The chipset is also discontinued although chinese manufacturers still have massive stockholdings going into boomboxes, the trick is finding them.
Pics and instructions to follow tonight.

Well, the actual ones that were originally spec;d were the RC-EZ31 and RC-EZ51. One person got the RC-EZ32 to run, but it wasn't easy.

Search for those first. There may be some on ebay. Buy 2 and then you have a spare controller board if you mess it up on soldering. The replacement mechanisms are cheapo on ebay.

I purchased a spare unit that I'm willing to sell if you're interested.

The mechanisms on eBay are mostly cheap copies of the Sanyo. The all look the same but are definitely not. The mechanism hasn't been made now for some years with the Sanyo markings. Most have no markings, or just 101N.

To whom it may interest, I have seen lots of the original EZ31 on the shelves at Zellers in Canada. They still do not seem rare here in Quebec as I've seen them elsewhere also.

Unfortunately Zellers online arm does not sell into the United States as I discovered to my chagrin when I first started working on my clone.

I'm the one incidentally who built one with the RC-EZ32 - still works just fine. Was not that easy to get it working, but the details still exist in the early part of this thread if you happen to find one of these.

I'd be interested in sources for the chip set if you happen to know of them.
