genius way of fixing the three little buttons that were missing. spray them gold and you'd never know! Mine is missing two of them but there is a little black spike that I can press instead.
I have a Kenwood KE 7090 Graphic Equalizer worked fine still sort of works but I've noticed when the unit is in standby mode the display is now displaying red horizontal lines which never appeared before, any help would be much appreciated 👍
i got one of these equalizers today for 20€. but needs some cosmetic restoration and 2 pushed buttons like yours.. the original graphic spectrum is gold color. I see yours is white. did you clean the front visor from the inside and lost the gold tint?
Hi Nick, nice video. I just bought this and I must admit, it is a beautiful unit and I love it. However, small issue, when I change the values up and down or the presets A, B, C, ext... there is a one second distorted spike comes out of the left channel. Can this be a caps issue? The spike is even shows on the left channel level bar as well. Please advise. Thank you.
Nick, Just picked up the pioneer from a thrift shop and all is perfect but it’s missing one of the gold buttons, please tell me how you made them, I am so impressed with your work in the video. Any help on making a button would be great, have not taken it apart yet but the tape monitor which is the missing the button has a tiny pin like piece of plastic sticking almost out of the front chassis, it’s just flush but if you take your fingernail, you can press it in and it works, so I was thinking , maybe I could fix it from the front with something very tiny and round with a tiny hole drilled in the back of it to slide on to my tiny plastic shaft that I see, and help or thoughts would be great, thanks
Hi. I used a small rubber/plastic cap that comes with a Receiver aerial (27Mhz) tube , that is used in model radio control cars etc. They were a perfect fit. They are very cheap, about $1. I am sure you can find them on Ebay
@@nickadams5411 thanks Nick when you take the front off the little cap goes behind this little piece of plastic for the tape monitor do you have to remove anything or can you just slide it in there please advise thank you
@@equalizr1958 Hi, Soory, it was some time ago, I can't remember. The video has quite a lot of detail. Not sure how much of yours is broken, but it only has to operate the micro switch.

Do you have any issues with the sound input being too low? My PC's headphone jack needs to be at full volume otherwise it doesn't really show up on the spectrum analyzer...
Hi. I do not have that problem. But I do feed all my inputs throgh a Denon PRA-1200 Pre-amp, so I can balance the levels from some records (vinyl) and Cds etc which vary in volume. A PC headphone jack, has a volume control in the computer, make sure it is set to maximum. Nick
Hi Nick, please help. When I set an EQ ( I create it at my choice) and program it if I do not turn the GR 777 on for a couple of days it is erased. Furhtermore when I want to set an EQ ( I create it at my choice and want to program it ) in key A, 3 individual frequences ARE NOT IN cero at the very beginning.Ever ytime Iturn on my GR 777 these same frequences are not in cero. Please consider I am not British, so if you can try to explain easily. Thank you in advance. Pedro
Hi Pete. I am not sure. The memory has a large capacitor to hold the voltage. It may have failed causing the memory to be lost. Are the levels only wrong in memory "A". Are B, C, D , E all good?
Hi Nick, i am the owner of a gr-x540 that's very similar to a gr-777 internally but externally it's a midi format component. I was surprised when i started to use it with my hi-fi chain (amp AX-340, cd pd-x950m) and it dostorted the sound in flat position! Also with eq button in off, so i can only remove part of bad sound only using it as "negative", pushing down the levels... When the levels are not touching the top of the displays the sound return acceptable. Is it time for a recap? thanks for the videos and for your attention. Riccardo
Hi Riccardo The Gr-777 has the same limitation. The highest bar must not exceed the top or the sound distorts. There is no margin for overload. The individual frequency bars are often higher than the Level bar on the right. It is important to keep the highest frequency bar below the maximum level. It is a design flaw?. A recap will not change it.
Thanks a lot Nick! I had a doubt about capacitor fault just because it was made in 1988, 30 years ago now! It's a little bit crazy that Pioneer sold it in a rack with other components that pushed a too loud signal to be well managed by this kind of equalizers. I'va also a Technics SH-8046 and when its bars toucked the top, the volume never distorted! Really thanks for the news
I have a preamp with a level control, so I can adjust the level from different sources, so they always are just below maximum. Without that, some outputs , such as CD will be too high for the equalizer.
Thank you nick. I proceeded to download the service manual on hifiengine but my old eyes can locate the location .Could you tell me where to locate this capacitor on the pc board???? Thanks my friend!!!
@@nickadams5411 Another old stupid question, is this a supercapacitor like those button cells??? I can't find on the very poor printed service manual where the location is.
Hi You turn on the unit, and the displays all go to maxim (both channels) You disconnect the phono leads and display is still full. 1. Are both channels the same, at maximum display. 2.

Bought this EQ brand new in 1995 with remote control still works.
Best way to replace these broken parts is custom 3D printed parts. You redo both side so the color match.

How does yours have blue LEDs? All of the others I’ve seen are amber LED’s
USA version has amber, UK or Europe has blue. Remove the plastic amber filter on the back side of plastic cover and you have blue.
