Just want to give you a little status update. We have prepared the producers desk bucket for the additional 8 channels. We had to relocate the plasma motherboard a bit and will install a frame to make room under the bus cards for the connector panel. The panel will hold computer ribbons and the power supply cable. All audio connections will be on the other side under the patchbay. Speaking of, we removed all patchbays and are currently trying to get through the snake nest to configure it to our needs. We have to rearrange some of the EDAC connectors (no DLs for the BBC) and have just received the tools to do so. Still waiting for the Atomic to power it up. Meanwhile we started removing the switches from the channels to give them some ultrasonic cleaning. It seems to help especially with the routing switches. The knobs and switch caps will get a bath though we are still arguing, should we put them into the washing maschine or the dish wascher.
There are also a few questions that came up through the last days.
First, there are different type of capacitors throughout the console. I know, that some have been replaced at some point. There are a lot of the orange ones, some kinda dark blueish and some in "british racing green". Among the photos I attached you'll find one of a channel with all kinds on different boards (preamp, dynamics, vca). Can anyone shine a light, which ones are most probably factory original and which one might be changed? It's mostly out of curiosity , I know I better recap but I will start with the center section.
Then we have removed an eurorack under the producer desk which had, besides some custom switching electronics, fitted several "dual switching/buffer card 82E148". As far as I can tell, these were used to disrtibute certain signals throughout the (BBC) studio. Am I right that these were used to balance signals and bring them to the right level/impedance? What else do these cards do? Any idea what I can do with them?
As I mentioned earlier in this thread, the desk had two custom BBC 682 panels fitted. On one, there are two switches labeled "A-H solo inhibit" and "25-32 solo inhibit" (see attached picture). Do they provide some kind of "solo isolate" for those buckets? I wasn't yet able to figure out, where the cables go. Any ideas? As I have lots of switches to spare, I thought I could install this for every bucket or at least reassign one of the switches to another bucket.
As always, any help is appreciated. Thank you.
Cheers,
Martin
