Fortunately some companies started to produce them again. The biggest challenge was to rectify the distortion of the image emd by the camera lens. Oberheim OBX voice-card replica creation wintermute. Some of them can be switched high or low such as sync and the waveform.
In these instances I used the schematics and took a best guess based on the overall PCB design. So it is possible to “copy” the layout from the image. I hope they do work as the originals. The next challenge was to wire everything up to test it. So the first information I gathered was the schematics, some photos and I was lucky to also find the original PCB layout.
Category Browser Open all Close all. As expected some of the parts are out of production for a long time.

Eliminate Procurement Problems Process: In some cases the PCB layout was blurry or covered by some of the components. Lets work together for the electronic development We can provide the following parts1. Most of the controls just use 0 to 5 volts as a CV input. The final test rig looks like this: You must be logged in to post a comment.
It is a transistor array consisting of 5 NPN transistors. After doing some analysis 78p15a cause could be rooted to out of specs components produced by Central Semiconductors.
TLVAIDR,SmdCode:TL,Package:8,Manufacturer:TI – Marking Codes
After creating the PCB I started with sourcing the parts. Oxygen Electronics is committed to fighting counterfeiting. If you have any doubts please contact a professional service. We can provide with capability in support to multi-category, multi-specifications,multi-variety and high volume parts,the quality is good and with good prices.
These are vintage Molex connectors not used anymore since the 80s probably. In the photo you can see the circuit layer on top of the image of the original PCB.
So looking ahead I need to some up with a strategy to substitute those parts with more current technology e. After printing out the component placement plan see attached documentsI will start soldering today.
Looking ahead I will come up with a solution to replace them.
After replacing the transistors I finally had two working VCOs. Meanwhile I will create a new design of the voice-card using more recent components. I could rectify this mistake by cutting two tracks and adding a small wire.
Increase Productivity Superior Process: If all you need is price tendency, visit Pricelynx. Life Support for the Procurement Process. I did a small prototype run first to see if the board has no errors.
78L15 datasheet datasheet & applicatoin notes – Datasheet Archive
To create a faithful replica I tried to copy the layout as close as possible. Exclusive Access to Electronic Component Inventories: The sound is legendary. For our best services,and good quality, We have got their trust support. The boards will probably arrive next month. After tuning the VCOs and some other initial calibration I was finally ready to make a little demo see below for video demonstration.
The author of this tutorial states that you 78l15z exposed to low voltage.
You can download our educational brochure on how to spot counterfeiting and the very latest list of counterfeited parts from Brokerlynx. We have been services with honesty and winning with quality based on the business concept of Quality First Customer Foremost. This replica ICs perform identically to the old-school ICs. We expand actively domestic and international market, understand highly the market changes,in gradually vigorous market competition, the enterprise scope have been expanded continuously, our net-selling are all over the domestic, and now we are expanding the international market We attach importance to the technique ,and observe the market change, have the ample sale experience, we have our own stock with large quantities, at the same time we have built up a cooperate net with the factories and Agents in USA, Europe, Japan, South Korea, Taiwan, etc.
The PCB layout data was send to a manufacturer and is now being shipped. Warning Level of difficulty: Please try again later. This project is to recreate the original voice card and eventually develop a drop-in solution for vintage OBX but also OBXa synthesizers.
Although we take great care about our tutorials neither the author nor obsoledo takes any responsibility for insuries, false information or any damage caused by this tutorial.
