Re-wire AC adaptor for JVC portable CD?
Posted 25 February 2011 - 05:46 PM
Cleaning my closet, and lo and behold, a JVC XL-R10 Portable CD player. Circa mid-80s, very heavy and well-built with a high-end feel. Google says it's similar to the Technics SL-XP7.
Problem: It has a really oddball power connection with flat blades. This takes a specific AC adaptor (same adaptor for both JVC and Technics models).
Luckily I have the connector tip (the blades) because I removed the player from a JVC boombox that featured the slide-out CD unit. But, just the tip and three wires attached.
I'd like to use a Universal AC adaptor, basically mating it to the tip's wire leads. BUT....(and here's where my lack of knowledge will be apparent) - the original tip has three blades (pos, neg and grnd) and the universal adaptor has just two leads I can see (pos/neg).
So, if I just hook up the pos/neg and don't have a ground, will I be jeopardizing the health of this CD player?

Dual 15v power supply means +15v - 0 (ground) for the first supply and 0 (ground) to -15volts is the second supply.
+15v --> 0v (ground) --> -15v.

Seems my old universal adapter won't be filling in, but luckily partstore.com sells a replacement.

This CD player was actually on my wanted radar... I wanted a 1986 era portable JVC CD player to go with my pre-CD player boomboxes and this was the exact one I was looking for. A while back I bought an original brochure for it and I knew that was it!!!!! I finally found one on ebay a few weeks ago and it works great and is in very good condition. It did come with the power adaptor... that was a must for this odd-ball. So if you need any specs off the original adaptor, or need some output voltages read let me know, I will be happy to check for you.
Nothing for sale though... this is a keeper for me!!!

As for specs, I've got both manuals (operating and service) for this model, so I'm good there. I think my strategy will be just to keep watching ebay for a parts model or the standalone compatible adaptor, and in the meantime see if I can pick up one of those benchtop/testing power supply units so I can try the player out.
Since you have a working model, what are your thoughts on this JVC player? How's the sound quality compared with your other units?
And, any chance of getting a brochure scan?

No problem on the scan swaps, athough I can't get to it for a couple of weeks. Just learning to use my new scanner, and work is full blast. Will let you know when they're done.
