Just finished the SSL!

[moogfrotee]

Hi everybody,
I´m new to this forum and just want to say "hi",
and report that I just finished the Gyraf SSL clone.
(got the PCB from Audio Kitchen).
When I powered it up for the first time it didn´t work,
and I went realy nervous, but than I found out I just had forgoten one of the bridges on the PCB.
? I was lucky man,? powered it up again and it worked.
And it sounds awesome.I got a TAC Scorpio and it´s just great together.
It was my first DIY project but now I want to do more, especially tube stuff.

I´m still a beginner but I learnd a lot from all you DIY people out there,
(yes? I´ve been watching you):wink:
I want to say thanks for that!

Hi,

I´ve got a question already.
I need some help with my new GSSL.

I just realised that the VU-meter is acting kind a strange.

do a need to change the 2k resistor for the VU-meter?
and if,which value instead?
or do I need another kind of meter?
can anybody help?

cheers

which VU meter did you use?

 

[moogfrotee]

I bought it on ebay from the US. its smalish and sort of old
looking there was a tag with a date from the 70´s on it.
it´s sealed and the brand is: DeJUR U.S.A there is writen "Bal"
with a pencil on the back,thats all I know about it

cheers

no clue... maybe try some different resistor values in place of the 2k. I know the behringer meter needs a 3k3 in there. Play around til the meter looks right, unless someone else has the answer...

 

[moogfrotee]

thanks so far
I will try 3k3 and see what happens

err
for the Gssl .... it's not a VU meter

I think it is a linear scale current meter.

 

[JPrisus]

That's right Kev, it is a DC linear 1ma i believe... but the behringer unit is actually a VU, isn't it? so maybe changing the value of the reistor to 3k3 might do the trick for this meter as well?

 

[Kev]

oh ! ... OK

then use a trim pot and just set to a desired level ... but remember that things may look a little different as this is a VU meter
... BUT hey It's your DIY.

you can replace the trim pot later with a permanent resistor after measuring the resistance you have just set.

ähhh... as I mentioned before?
I´m sort of a beginner (but a good at soldering one).
where do I have to connect the middle pin of the trim pot?
to ground?

thanks guys,

Could you make some audio samples? Would be great...take something dynamic (and not already smashed) och compress..move the nobs some live and bypass in and out...would be great!!!

:roll:
if this is a 25 turn trim pot then it might be easiest to use the middle pin and one other end as the Variable Resistor.

The 25 turn pots give more control and are not so touchy.

Ounce you have the meter doing what you want then you can unsolder and measure the resistance. Remember which outer leg you used.

o.k. I´ll do some audio samples.
just give me some time (a day or two) to do it,
It´s to busy right now.

Thanks Kev,

I don´t know how I could live without you.

does anyone have a parts list for the SSL comp in exc el format?
