Testing...

Added: 15-4-2004 0:56:45

Everything is in place and the testing can begin.


Everything is working! I really didn't expect this. After reading all threads about SSL clone problems on the Tech Talk forum, I thought I would be encountering some problems too. But the thing is working fine. The sound is very good, punchy, not really subtle. The extra white wire is not in the scheme. It's an earth connection to make the clone less noisy. I might remove it once the clone is put in it's 19 inch case.



Enclosure

I put everything in the enclosure. All there is left to do is waiting for the Sifam knobs and meter, a couple of weeks....



Sifam 14 PPM

Added: 10-5-2004 14:15:53

Today I contacted the Dutch distributor of Sifam and he told me that the "Director 14 PPM" meter will be ready on 21 May. So, the project is now on hold. The distributor allowed me to buy the gray Sifam knobs with blue caps in small quantities. On the Sifam site they mention a minimum order quantity of 1.000 pieces. Before they got a chance to change their mind, I quickly decided to order twenty of them.


"A change of plan....."

Because of this thread on The Lab-forum I decided to make a sidechain on the GSSL clone.


This is the balancing circuit of the sidechain. I copied the input and output from the clone on a prototyping pcb. In the thread mentioned above you can find where you have to cut the PCB traces.


This is how the frontpanel will look like. An extra "Sidechain In" and "Sidechain Listen" button are now there. Almost like the original.


To create space for the two new buttons I had to detach the Lorlin rotary switches from the PCB. I connected them with wires.



Drilling holes

Added: 26-6-2004 15:12:21

Today I drilled the holes for the XLRs.


...and the XLRs in place.

The XLRs on the left side are for the side chain. I drilled 10mm holes. After that I made larger holes with a round hole punch. I'm very pleased with the result. The front plate will be done by a professional company, because my drill press is a bit wobbly.



Finally there

Yes, there they are finally: the PPM 14 meter and the knobs.


I started right away.


I made an extra aluminum plate to prevent showing the bolts from the switches on the front.



Lazertran

Added: 26-8-2004 16:21:39

I want to do the lettering on the front panel with Lazertran. This is a sort of transfer paper. Thanks to Twin X, for printing mine.


I'll do some practicing first on some aluminum plates...


The real thing...

For an explanation on the Lazertran method you can read the Lazertran site and Frank's DIY-site.



Finished

Everything is in there


My second clone is less messy inside...


The front, and it still sounds superb!
