JVE SEA-70 - Thoughts and Advice Please

[PTL-Pioneer]

Hi
Just ordered a JVC SEA-70 for myself - never had an EQ before so would like to play around with one basically, i know most think they degrade sound, another thing in the chain etc, but hey, why not try one and play about with it.
So i have downloaded the service manual and user manuals in anticipation of receiving it.
I think from reading advice here, the equaliser connects to the tape monitor input/outputs??

Is deoxit faderlube sufficient to clean all the sliders safely?
Any and all help and advice on this especially how to set one up properly settings wise would be very much appreciated, thanks

They are fun, and JVC is one of the better ones in my opinion. I have an original JVC 4VR4554 quad receiver with Front and read equalizer built in.
I suggest that you use air first to blow out dust
If they are spotty I would suggest using fader jube F5 in each to clean the control
Then I suggest using faderlube FL100 liquid with its needle point, to put a small drop of the lube on the slider pivot points left and right so that the control moves smoothly.

Got this advice from someone here at this site (thank you , original poster)

One tip with eq's learned the hard way...
If they haven't been used for a while resist:nono: the temptation to just squirt switch cleaner or any kind of lubricant into the fader pots.
If you do they will feel slippery for a few hours...then once the existing silicone is diluted and the switch cleaner evaporates...they will suddenly feel very gritty and hard to move.
The carbon track will also be contaminated with the existing grease that has been diluted which is neither good for the sound or the life of the pot.

Better to work each slider through their travel a few times to restore the smooth movement as the lubricant on the underside of the opening slots will have collected at each end of the pot.
The carbon track directly ahead as you look into the pot should be as clean as possible..but that is not where you want to apply any kind of lubricant. You want the lubricant applied on the inside edge of the slider opening. Bending a hairclip into a U shape and adding just a *tiny* amount of silcone grease on the reverse face of the actual slot opening (both sides of the slider itself) should restore smoothness.
The carbon track directly ahead as you look into the slider pot can be carefully cleaned with a cotton bud dipped in switch cleaner with a built in lubricant like servisol 40 ,faderlube FL100 but be careful not to dilute the silicone grease on the underside(reverse side) of the slot opening.
Clean the track first...then add a tiny bit of silicone on the reverse face of the slot opening using the hairclip second and work the slider through the full length of travel a few times very slowly to distribute it.
Should keep them smooth for years. :thmbsp:
