Panasonic RQ-J20X "dbx" RARITY

johnedward - 2009-10-17 12:39

What an exciting day this arrived this morning. Truly one of my now most prized Walkman's and a DIAMOND among them. The player is an unusual brown/grey metallic with two tones darker being on back half. It was released in 1982 or 1983 and is based on the Panasonic RQ-J9 model. I do not know a lot about this model so please anyone with knowledge please share. The icing on the cake I paid $30 USD !!

I believe the only other walkman to ever be made with dbx is the Teac PC7RX. Jazzrat2000 has the Teac with dbx. TIM would be great if you could post a picture of your Teac here.

A lucky "expensive" find almost a year ago.. BRAND NEW in box dbx PPA1 decoder for portable Walkman's. Amazing ability to wipe out tape hiss far exceeds Dolby and does NOT cut out highs. Have to really play with recording levels and dash pots on DBX 222 encoder/decoder to minimize the dbx system drawback of "breathing" but when right it is ASTOUNDING...Sadly its lot to carry on the belt the Walkman, Sony SEQ-50 and PPA1. "WIRED" I would say Laugh Out LoudLaugh Out Loud .
The PP1 also adds nice level of boost to volume. It has a setting that is a Dolby B compatible decoder so Dolby B recorded tapes can be played back if Walkman not have.
VERY NEET IDEA and rare to find.

Great " dbx " site for those curious.

DBX HISTORY AND HOW IT WORKS

OH MY GOD... Now the forum knows I have a BOOMBOX... what a beauty too Toshiba RT-SF5. Sound is excellent as long as your not trying to push it loud. SSHHH Actually have several Boombox's just not jumped into the boomer side of forum yet. Here is the dbx 222 have been playing with for recording. Hassle is once you record dbx tape you have to use a dbx decoder otherwise its like a MP3 even more compressed with high and low freq. range squashed into middle.

Oh yeah sitting in back left a Sony PS-X600 gotta have the analog direct drive Vinyl machine with ultra rare Dynavector Ruby moving coil cartridge...I bought new in 1981
Smile Big Grin UH OH.. now am admitting age... Laugh Out Loud
My Nakamichi LX3 is in the shop for repair so the Yamaha handling backup for moment.

Nice Panasonic I think I bidded on that guy.

johnedward - 2009-10-18 13:12

Was unusual bid situation item had been up for few days and a $10 opening bid. No bids. It was 11 pm at night when I saw it noticed in comments seller said make offer if accepted would put on a BIN option. My first email asked function condition she could not verify operation and a noise was in headphones while tape played ( obviously from her response wording she knew nothing about Walkman's). Also picture was only of player inside case so had no idea how really clean or not it was when bid and accepted her BIN. I made offer few mins. after I first saw and asked here to test player. She replied instantly. Got lucky she accepted my offer and within seconds of BIN put up I clicked. Next morning she said she had two more offers already since mine but would honor my BIN. Was lucky for once at right place right time. From when I saw it to me clicking BIN less than 10 mins. went by.
Totally astounded at the cosmetic condition when I got it and build quality of player. Not a mark on it even clear window. Tape transport works perfect and steady speed.
Has a odd constant electrical pop pop sound in headphones that if hold mic switch hard to off stops and if DBX turned on it increased same sound. From reading on here other problems my guess is simple grounding problem or wiring situation with Mic switch. Do not think it is anything serious. Can anyone suggest what problem may be and how to test or repair?


ANYONE have Service Manual ? ? ? I dont want to open up with out that help.

The service manual seems impossible to get-either in paper or PDF form.

Very nice walkman and pictures! Cool Smile

Thank you Nicole... kind of you to comment. I do try very hard to be creative and put up excellent pictures. I often take 50 pictures of one Walkman to find a few perfect ones.
