EQ in and/or Split in cuts signal in the channel ------SOLVED------

[Dave Dicson]

I have not had any trouble with the Filter pots. Sorry I don't remember which ones. probably level? I'm not sure which Eq you have, but the G series Eq has four sections. If any one of those sections has bad pot(s), they will kill the signal when the Eq is turned on. I have three 4K SSL consoles, and it has happened too me, but not very often. I've had pots that grind when turned.

Don't neglect the Dynamics switch card, particularly the Channel Out switch. Given that this switch changes the order of Dynamics and EQ, I believe the EQ'd signal needs to pass through this card as well, regardless of whether the switch is pressed or not.

Hi,

Thanks to all one more time!! I would not be able to do all maintenance work in my loved SSL4040E. I finally could fix the channel 31!!

This channel is one of eight SL611G fited in my console.

I have started replacing the frequency pot of HMF section, after cheking the Dynamics switch card (as suggested Chris in his post).

The first pot replaced... I was testing if something have changed... and when I was testing... I have touched the +15/-15 trim pot of HMF.

I have realized that touching one of the pole of the pot... signal was coming!!

I have removed the covering plastic of the pot... and I could see one of the two white cables was peeled and touching the other pole! It is crazy!

So I have added a new heat shrink piece to the peeled cable and a bigger diameter trasnparent heat shrink for protecting all pot poles pins.

The pot works fine, the issue was the short between these two poles.

I have attached some photos as info for anyone who could have a simillar issue in the future.

Thanks to all for the support and help offered in this forum.

Very best regards.

That's a new one I have not seen before.

Well done finding it.
