Fortunately 2N and 2N work perfectly. After doing some analysis the cause could be rooted to out of specs components produced by Central Semiconductors.
After creating the PCB I started with sourcing the parts. Powered by Hong Kong Inventory Limited. It is a transistor array consisting of 5 NPN transistors.
So looking ahead I need to some up with a strategy to substitute those parts with more current technology e. So it is possible to “copy” the layout from the image. I 78l5a they do work as the originals. Please try again later. 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.
It is this consistency which enables Oxygen to continually improve our levels of customer satisfaction. You must be logged in to sjd a comment. Today the prototype PCBs and some other components arrived.
The 78l5a OBX synthesizer is one of the most sought after vintage analog synths. Oberheim OBX voice-card replica creation wintermute. Our proprietary data and data systems enable our staff to understand Pricing trends, historical availability, and a myriad of other factors ensuring we can always negotiate the best pricing! Some of them can be switched high or low such as sync and the waveform.
After replacing the transistors I finally had two working VCOs. Life Support for the Procurement Process.
The PCB creation was straight forward. After tuning the VCOs and some other initial calibration I was finally ready to make a little demo see below for video demonstration.
Distributor Of Electronic, Military, Obsolete & Passive Components.
The image shows how I arranged the controls. The boards will probably arrive next month. Our in-house-designed fulfillment process ensures that every transaction is handled identically every time!
First I started with the VCO section. Basically one could use 5 transistors instead. In some cases the PCB layout was blurry or covered by some of the components. 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. The author of this tutorial states that you are exposed to low voltage. If you have any doubts please contact a professional service. If all you need is price tendency, visit Pricelynx.
Eliminate Procurement Problems Process: In the photo you can see the circuit layer on top of the image of the original PCB. The last rare part of the voice-card are the connector sockets on the PCB.
Oxygen Sm is committed to smc counterfeiting. I got some of the first prototypes of the IC. Warning Level of difficulty: The final test rig looks like this: After printing out the component placement plan see attached documentsI will start soldering today.
The PCB layout data was send to a manufacturer and is now being shipped. You can download our educational brochure on how to spot counterfeiting and the very latest list of counterfeited parts from Brokerlynx. Because I do not own a OBX nor a single voice-card I had to work with the material available on the internet. Looking ahead I will 7l15a up with a solution to replace them.
Most of the controls just use 0 to 5 volts as a CV input. The biggest challenge was to rectify the distortion of the image caused by the camera lens. We can provide with capability in support to multi-category, multi-specifications,multi-variety and high volume parts,the quality is good and with smdd prices.
These are vintage Molex connectors not used anymore since the 80s probably. This was challenging because I first had to figure out what voltages are dmd at each of the control inputs.

We have been services with honesty and winning with quality based on the business concept of Quality First Customer Foremost. In these instances I used the schematics and took a best guess based on the overall PCB design.
This will help to spot errors which then can be corrected in smr layout. To search for more components and get quote from us, please use our Part Search: I did a small prototype run first to see if the board has no errors. Category Browser Open all Close all. I will use them for the prototypes though. I will compare them as soon as I receive the prototype PCBs.
