My GSSL - finally finished

[Purusha]

Thank you very much sir! :thumb: :grin:

So it's possible with 1x12 after all :!: I just had a quick look. If I see right, there is also Stephens circuit in the schematics. Man, this is really great. I think the new PCB layout for the whole thing is the only thing missing now. Neeno, are you inspired to finish the additional Thrust PCB which you started already?

I can't wait to build this overkilling side chain hi-pass filter :green:

I see no problem, but note that it's existing just on paper right now. Let's just build it, if there are some changes required they will not be hard to do.

OK. But one more question before I start soldering. If I follow your last schematics 100% the way it is, will I miss something? For example Neeno's PCB had an extra 100nF in the PCB layout which was not there in your schematics...

I am no expert so I might miss something which is a basic thing for you, maybe I should just wait that someone makes a new PCB layout?

Hi,

Please read note *4* in the schematic.

But as said before in this thread, use two 100nF, the first one from pos sup to gnd & the second one from neg sup to gnd. Place both close to the 5532.

Just do it, it's just the sidechain-filter for a compressor. I sure understand you want to do this as good as possble right away, but nobody's life depends on it. :wink: So just start & don't hold your breath until all details are known, seriously ! Please do make a few mistakes, you'll have learnt more from it that way :wink:

 

[clintrubber]

Please note C22 in my schematic has the wrong value: 150nF should be a 47uF electrolytic.

 

[Purusha]

OK. I'll start right after I finish recording one band after a couple of days :thumb:

Thanks!

NICE WORK CLINTRUBBER :thumb:
I think i'll start working on the pcb next wednesday...

Work is killing me :roll:

My pleasure. :thumb:

What are you going to do, put the complete sidechain filtering on your PCB or just the added thirsty filter ?

If you want to be sure about the drawn circuit maybe you could wait with fabrication of your PCB-design until someone has tried & tested the veroboard-version. For mine that won't happen before upcoming wednesday though, have some busy time at work coming up as well.

Bye,

Peter

NO hurry, guys! Take your time, I have also a lot of work this week. Otherwise I was thinking to add the Thrusty to the veroboard next to Greg's PCBs. I already bough the veroboards this time so maybe I'll make some PCBs next time.... :thumb:

Thanks for all your help and don't forget to post your Thrusty PCB layout when it's finished. :grin:

 

[Purusha]

Hi guys,

any progress with the PCB layout fot the new Thrusty, yet?
I am still too busy to make any progress at the moment.

Neeno, what program did you use the last time for drawing your layout?

 

[Purusha]

Well, I was thinking to make some progress with the Stephen/Thrusty filter but I don't know how to solve the power supply decoupling thing. I was hoping some of you will make the new PCB layout soon so I can see how to solve this :wink:

Peter, Neeno, anyone?

 

[Purusha]

I think I got the decoupling solved...

BTW, will 15v+- be OK for Thrusty?

 

[Purusha]

OK, I made some progress with the dual Thrusty&Stephens HP filter. It's not fully wired yet and my 8 G-SSLs are not completely ready to test the filter but I feel very optimistic so far :grin:

Here are some pictures of the filter in progress :green:

 

[Purusha]

Is this the right way for decoupling ... ?

 

[clintrubber]

For some reason I am not getting mail-notifications of updates of this thread. So hadn't seen the progress. Nice.

Yes, that decoupling is fine. Put those caps close to the IC.

 

[clintrubber]

Don't have the schematic here, but what are those four trimpots for on the right ?

 

[Purusha]

I was waiting for someone to ask :green:

They are there for my extra VCA CLEAN/COLOR option. I don't know how the two different settings of THD trimmers will effect the sound at the end but it might be a good idea. Here is my front pannel design.

Click on the picture and zoom in for better view :shock: :grin:

You've been busy :thumb: Nice to see a different colour, are you going 'SPL Gold Tube'-look ?

Ah I see, so with the frontpanel-switch you can change from trimmed to deliberately untrimmed ?

Let us know how it turned out.


Bye

You've been busy Heck Yeah! Nice to see a different colour, are you going 'SPL Gold Tube'-look ?

Something very similar, yes :wink: I'll post some pictures of the finished chassis next week.

Yes, that is it. I'll maybe post some sound clips when I am finished with two colour samples.

 

[Purusha]

Peter, can you recommend a good spot where to take the voltage from for the thrusty?

Would + - 15V be also OK? I think it would be just the same.
