andyboombox - 2010-06-10 04:43

right guys
all being well im gonna be buying one next week-ill have a look on ebay uk-but before i do-i need your reviews please-your honest opinions of this model-and also-its nearest rivals and how easy to get in the uk.
i know its got a good following but let me know how you rate yours please-or should i be looking at something else? Wink

lav.loo - 2010-06-10 05:01

it,s an awesome box andy, you would,nt be dissapointed with a 777 No No they bang mate Nod Yes Wink

andyboombox - 2010-06-10 05:12

cheers az-nice one-now, who else has their thoughts?

im.out.of.hear - 2010-06-10 07:24

i got one,there lovely,mine is even more lovely because i replace the bog standard paper outer bass with the good quality 25w ones,and it looks nice aswell..

Mine started like this..



and ended like this..


im.out.of.hear - 2010-06-10 07:35

Oh yes,as for sound,the 777 is'nt like your typical sharp distortion box (which alot of sharp boxes do) they did something right with this one,wether it be the cabinet design,amp,speakers,i dont know,but these sound nice and bassy,loud,they feel solid..

But...one word of warning Andy ! make sure you get a good all working one,because when these go wrong (even the cassette decks e.g Rewind/FF faults) they can be a real pain to repair !! they can develope some spooky pain in the ass faults that are a nightmare to fix..But...if you get a good one,you'll be ok..

Oh and as for price,Typically on ebay,for a good un-abused one,you'd be looking at £250-£350,crazy i know (i would'nt pay that) ! but thats what the market is saying right now

retro.addict - 2010-06-10 07:41

gettoman, when you replaced the outer woofers, did it improve the treble? I find that mine sounds pretty flat, the awesome bass just overpowers everything if you have it turned up, it's just a mega bass machine. I'd like mine to have much more highs. Oh and also, it would be my preference to have the replacement woofers black to match the inner ones. Nod Yes

lav.loo - 2010-06-10 07:46

yes i forgot to mention the highs are not too good andy, and like RA i like highs too Nod Yes maybe that won,t bother you though as i think your a bass man Nod Yes
love the conion by the way G,MAN Nod Yes Wink

im.out.of.hear - 2010-06-10 07:56

Retro,with me,i first really wanted a 777 about 7 years ago,but before that i was'nt really interested in them..but when i saw this pic i fell in love with them..


I was determined to make mine look like that,it just makes it different than the norm..it looks lovely..as for the sound,i think your right mate,the bass can kill the treble a tad if its turned up too much,and if you hit the subs up too much they can flap and crap out,i'm not sure about the outer bass giving more treble as i have'nt used the 777 in a while,i mainly like it to look at..it definately sounds alot better with the white outers than the standard outer bass,these ones i put in sound more beefy and it can take more of a thrashing before it distorts..

im.out.of.hear - 2010-06-10 08:01

Lav,yeah the conions a monster,alot bigger than people think ! but mine has been a problem child ever since i got it,and cosmeticly,its ok but its not mint either,and there a pain in the butt to work on..i still like it dont get me wrong,but i'de much prefere to swap it for a GF999 or Lasonic 975,only prob is,there aint anyone in uk willing to swap..

lav.loo - 2010-06-10 08:35

to be honest id rather have the conion over the 999 or trc975, it,s the mother of all boxes Nod Yes surely somebody wants a swap Wink

My 9494 doesn't distort too much even when I put it at maximum volume. Said this, the 777 it's my favourite 'box of all times Nod Yes !

bendycat - 2010-06-10 13:28

love my 9494
and a few other that i have yet top sort out

but for sound th xbs 680 is da bomb on bass - which makes me wonder if the speakers could be changed over to a 777 to beef it up ??

Andy where are you getting yours from ?
and did you think about the other one's 1000 909 - 919 - 999 - 767 ?

jayt - 2010-06-10 14:02

Andy V, You will be very pleased with the GF777, I know just look at my Avator.
<----

lav.loo - 2010-06-10 14:51

hey jay, im comin over to yours right now mate, youve got too many 777,s so il,e take 1 off you Laugh Out Loud Wink

im.out.of.hear - 2010-06-10 15:47

yes jay,your floor is just about to cave in,quick,get some of those out of your house,i think you need a conion to replace one of them..

Some people do come in handy ey ghettoman Smile

andyboombox - 2010-06-11 02:12

great comments-thanks all-hey b-like the other models but gonna allow upto £500 delivered.also considering a toshiba wx1-cos i like them too-we'll see Big Grin Wink

Andy,

I'll try to give more detail to help you make up your mind. I'll warn you, this one's an essay.

Bass
----

The outer speakers are full range but have a deeper and richer bass the the inner woofers. It has been observed by one poster that if you switch off the inners speakers you can get a more pleasing sound.

The inner speakers have a limited bass frequency response. The speaker units say 30Hhz to 8KHz but what you hear is more like 100 to 500Hz, which is partly due to the crossover circuitry in the box and partly because the stock speakers physically cannot reproduce low bass.

To get the best bass sound I find the turning up the master bass control to about 3/4 and turning down the woofer controls does the trick. That way you can crank it up pretty much fully without distortion but you need to experiment with the music you play.

Mids and Tops
-------------

I don't think there's any box in the world that has a problem reproducing good mid-range so I won't dwell on it. The outer speakers will do a very good job on that and the inners speakers will support the out ones in giving voices your music 'body'.

When you buy your 777 it will be nearing 30 years in age and it will be a bit shy on tops. You can change the crossover capacitor to improve this, furthermore you change the tweeter. The tweeter outlet doesn't help; more of the high frequencies are lost because of that horn design being used with a speaker that is not designed to be used with a horn

All-in-all
----------
The box sounds quite pleasing with the original speakers and as long as you get one that's in good nick you won't be disappointed.

My observation with the sound is that this box can throw sound quite a long way for a boombox. For instance, my Crown 850 is quite q loud box and when your close to it you think Wow. But when you stand some distance away its really the 777 you hearing. I don't know whether other observe this.

If you change the speakers it comes to life in the most incredible way. I changed my outer ones for Kenwood car speakers and I recently found some 4 ohm replacements for the inner woofers. I also changed the crossover capacitors for bi-polar ones with a crossover frequency of 1KHz. The inner speakers produce the lows VERY NICELY now and the tweeters (both the Kenwoods and the original sharp tweeters produce the highs together really nicely.

You'll probably need a demagnetizer for your tape players and your box will probably need a service. You can get a service manual from Fatdog (legend that he is) on Boomboxery. The service manual will tell you how to recilibrate many of the areas inside the box.

There's a chap called Superduper on Boombexery (I think his name is Stormin Normin here) who suggests replacing all the capacitors in the box because over the years they dry out. I am no expert but I would agree because the change in SPL when I changed that tweeter capacity was quite something; I can't imaging what changing the rest of the caps would do. You have to be an expert to change all those caps though because there are just soooo many.

Hope this helps.

andyboombox - 2010-06-11 03:13

wow-mate-what a writeup-well done GLD!im convinced-a gf777 it is.i will be asking on here next week any members in uk willing to sell one to me, if i dont find one on the bay-the funds i have for the box will clear in my account by the end of next week so will be looking to part with the cash by next weekend definately-
GLD-top review and the clincher for me-ditch my 3d80-here comes the 777 Big Grin Wink

Hello Andy

I got a GF777 (a new, original one) - for me and my collection a must have. But when I did the first soundcheck I was very disapointed.

I know that you are a fan of the Sony FH's - they sound much better than a GF777. I'm looking for the best sounding units, posible with hifi-sound quality. And the GF is far away from that ... but that's just my opinion, as a sound freak ...

Look: 10 points
Sound: 6 points

Best wishes
TOM

lav.loo - 2010-06-11 06:51

but you got to consider this, ghetto blasters were made for street sound Nod Yes hi fi,s were made for the house Nod Yes so on that note if you want hifi sound from a box, you gotta get ones like the sony fh7 because their not street boxes, their more like a small hifi for the home Wink

andyboombox - 2010-06-11 07:01

I Agreewith you az on this mate Wink

im.out.of.hear - 2010-06-11 07:04

Agree lav,alot of the FH series have handles but dont even take batteries,also the technics Sac05 dont take batts,theres others aswell that are mains only..they cant really be classed as boxes..

gld - 2010-06-11 07:08

I agree Lav Loo. Boomers like the Sony FH7 and the Telephonic Studio run on seperate main power supplies which means there is enough juice to play music in high fidelity.

There Sony requires a seperate battery pack to be portable (try finding one!) and the Telefunken has two powers supplies I believe; one for mains and one for battery. There was another thread that said that when the Telefunken is run on batteries it doesn't sound that great; good but not great.

The M90 apparently blows the 777 away and that is a true boomer in that it does its work on batteries in the same way as one mains.

The M90 has a toroidal transformer (someone correct me I'm wrong) which is far superior to a normal one in terms of power delivery.

paul....i have 4 fh`7s and i where the power unit is at the bottom, i have a box that you swap over and it that takes 10 d cells thus allowing the ultimate portable sound with handle included

im.out.of.hear - 2010-06-11 14:41

Ahh dave,those battery units are RARE !! and you've got one ??? Bet you are one of the only owners of one of those Eek

andyboombox - 2010-06-16 03:04

With what input source? And what bass/treble settings? That's the key question.

I have one of these - they have an optional battery pack. The SAC-07 (?) was mains only I believe.

With an mp3 player playin' trough the mic mix input, with some songs you've to turn off the loudness and take down a little the bass but generally quality it's very high from this point of view. My usual settings are loudness on, bass all the way up, treble a little less. Obviously the mp3 player has to be taken at half or less of its volume or it'll be distorted at any volume.

You're using the mic mix input? That box doesn't have line-in or even phono inputs?

Phono imputs are there, line ins sadly not...there are any problems with that?

Well the mic input wouldn't be stereo, would it? A lot of people here use the phono inputs with a $15 line-in converter/booster.

miami - 2010-06-24 12:21

I see, I've noticed this matter sometimes with some songs but looks likes it comes and it goes...thank you for the advice man Wink!
