I just got his great JCPenny's boombox from Adam Thafuzz! :police:
It is in very nice dare I say minty condition and is fully working thanks to some new belts.
I love the look of this thing and it is quite large.
It is loaded with features and it reminds me a lot of a sony CFS66,77 or 99.
But I believe it was built for JCPenny's by NEC.
It seems well built and sounds very clean, not a lot of bass.
Adam packed it super well and shipped it to me fast in a couple of days.
Thanks Adam. :chris920: :rock: :bow: :thumbsup:
Here are a few pics.

5 Band equalizer
Analogue VU's
Digital tuner with presets
Dolby
Twin aerials.
Made in Japan

I got a brand new boxed one of these (NEC) version earlier this year locally and consider it an unbelivable score.
So many features for a one piece box.
Well done on an unusual box.

This thread just got even better now I know that there's a 250V version of that beautiful box! And Long wave radio as well, that's probably nigh enough the perfect one piece box right there.

What's not to like? Nowt! I Want one. :thumbsup:

Whatever became of NEC though but? We don't see their gear all over the shelves at Rumbelows' these days and that's a shame 'cos IIRC, they were one of the good brands and competed on level terms with the likes of Rotel, Denon and Trio.

Ha ha! I used to work for Rumbelows as a teenager in the late 80s! I've still got a 3D80 from back then. All the great boomers had gone by then though!

Yay! You received it, safe & sound. I really like this one, but I needed more room and hated to see it not getting played enough. I miss it already. I'm very happy it went to a fellow member here. Scott is a righteous Dude!

"Not a lot of bass"... that brought an idea to my mind, and I'd like to share it. I have a beater GF-575 and the other speaker had very weak bass. So, I tried to do a "manual break-in". What I did, I gently pushed the cone back and forth and gave the lower spider a little "massage" until the cone felt the same as the other speaker. After that the bass got better and the cones were moving the same amount. Before the "break-in", the less bassy speaker cone didn't move as much.

This is just an idea and it should be done very carefully. Some speakers have so hard suspension that they wont produce anything lower than say 70Hz...


Other way and probably more ideal, is to hook the speakers to a more powerful amplifier and run low frequency test tones right on the limit of the speaker (in free-air). At the start, the test tones should be higher, and then lowered step by step. In fact, the Fs (lowest resonant frequency) will drop when the suspension brakes in. Also the sensitivity can go a bit higher. When the Fs drops to the same frequency as the test tone, the impedance will go up and the amplifier will give less power. Then the test frequency should be lowered.This can be measured with a clamp meter (amps) and a multimeter (or two). I don't remember the correct procedure but it involved some math, and the result was resistance/impedance or something like that.

I was able to tweak a bassier output via my iPod's EQ setting to max bass (when playing it through the Line In jacks), and the JCP's EQ settings at max as well. I played a song with an 808 kick, and got a respectable Bassy response. The mids and highs are very clean and clear sounding, btw.
