Thanks mates,
this compressor is worth every hour I´ve spent to built it. It´s not really a difficult but quite complex built. Stuffing the boards was easy, wiring takes some time, mainly because I had neither a wiring guide nor a help thread as you have, but Volker was very helpful and gave a lot of hints, thanks mate.
The rotary switches took me almost two full days, since I haven´t done it before, but in the end everything worked fine. The Time Constant switch with 6 settings is fine, especially when you want to use it as mastering compressor. Soundwise I like the longest attack/release (6) most, because it gives the mix a very smooth and dense character.
As I mentioned before, a VU meter is the best choice and recomended by Rowan. Other meters work as well. I tried several, VU, 100 uA, 250uA and 1mA meters. I finally took the 100uA meters, because they looked and fitted best. Pay attention while fiddling around with various meters, there is fairly high voltage on the meters.
The uraltone switches are nice and quite easy to solder, although there are better (but more expensive) ones. The enclosure is 3U with 300mm depth from: http://www.modushop.biz/ecommerce/cat069_l2.php?n=1
Vented covers for your enclosure are highly recomended, 2U for a stereo unit is a no go. Stereo tracking (two channel linked) is fine now, the values for RV3/RV6, that Rowan gave us, are a good starting point.
I posted a lot of pictures here to give also less experienced builders an impression what it could look like and to learn from. I´m a musician and have only a vague idea of what all the components in there are good for. Well, I did some other tube stuff before, but honestly, I don´t have the faintest idea of all the maths that is behind it. With a bit of patience and care everybody should be able to build this nice piece of gear.
Thanks to Rowan for this superb compressor and to Volker for the splendid pcb layout. It was a real pleasure to beta test this beast (Volker, I love the T-shirt you made for me).
regards
Bernd
