Also after hours spend searching why the VCO is not oscillating I reached the point where I had to investigate the component level. It is a transistor array consisting of 5 NPN transistors.
Why Oxygen Electronics Is Your Essential Supply Chain Partner
These are vintage Molex connectors not used anymore since the 80s probably. The software I use has an option to load images as a layer. Meanwhile I will create a new design of the voice-card using more recent components.
Oxygen Electronics is committed to fighting counterfeiting. One of the most difficult and expensive parts to source was until recently the CEM envelope generator IC. This was challenging because I first had to figure out what voltages are needed at each of the control inputs.
Category Browser Open all Close all. The image shows how I arranged the controls. It is this consistency which enables Oxygen to continually improve our levels of customer satisfaction. The PCB layout data was send to a manufacturer and is now being shipped. To search for more components and get quote from us, please use our Part Search: I will use them for the prototypes though. You can download our educational brochure on how to spot counterfeiting and the very latest list of counterfeited parts from Brokerlynx.
To create a faithful replica I tried to copy the layout as close as possible. For our best services,and good quality, We have got their trust support. Unfortunately this is not possible because the VCO will become unstable due to temperature. Most of the controls just use 0 to 5 volts as a CV input.
In these instances I used the schematics and took a best guess based on the overall PCB design.
Increase Productivity Superior Process: I could rectify this mistake by cutting two tracks and adding a small wire. The Oberheim OBX synthesizer is one of the most sought after vintage analog synths. The final test rig looks like this: We have been services with honesty and winning with quality based on the business concept of Quality First Customer Foremost. As expected some of the 78l1a are out of production for a long time.

Today the prototype PCBs and some other components arrived. Fortunately some companies started to produce them again. So looking ahead I need to some up with 7815a strategy to substitute those parts with more current technology e.
In some cases the PCB layout was blurry or covered by some of the components.

After doing some analysis the cause could be rooted to out of specs components produced by Central 78l51a. So I desoldered all transistors and and the FETs.
In the photo you can see the circuit layer on top of the image of the original PCB. Exclusive Access to Electronic Component Inventories: Life Support for the Procurement Process. The PCB creation was straight forward. The breadboard and a dedicated PSU connect directly to the voice card. Powered by Hong Kong Inventory Limited. If you have any doubts please contact a professional service.
This project is to recreate the original voice card and eventually develop a drop-in solution for vintage OBX but also OBXa synthesizers.
