So I desoldered all transistors and and the FETs. Looking ahead I will come up with a solution to replace them.

After tuning the VCOs and some other initial calibration I was finally ready to make a little demo see below for 78l51a demonstration. I hope they do work as the originals. As expected some of the parts are out of production for a long time. The member registration is currently not possible. Eliminate Procurement Problems Process: The biggest challenge was to rectify the distortion of the image caused by the camera lens.

The image shows how I arranged the controls.

One of the most 78l15z and expensive parts to source was until recently the CEM envelope generator IC. This will help to spot errors which then can be corrected in the layout. Nothing to be worried about so far. After doing some analysis the cause could be rooted to out of specs components produced by Central Semiconductors. The PCB layout data was send to a manufacturer and is now being shipped. In the photo you can see the circuit layer on top of the image of the original PCB.

The author of this tutorial states that you are exposed to low voltage. And if you are just ssmd, use our Part Search features! It is a transistor array consisting of 5 NPN transistors. The next challenge was to wire everything up to test it. This replica ICs perform identically to the old-school ICs. This was challenging because I first had to figure out what voltages are needed at each of the control inputs. I did a small prototype run first to see if the board has no errors.

I got some of 78,15a first prototypes of the IC. Powered by Hong Kong Inventory Limited. Also after hours spend searching why the VCO is not oscillating I reached the point where I had to investigate the component level. We have been services with honesty and winning with quality based on the business concept of Quality First Customer Foremost. Today the prototype PCBs and some other components arrived. After creating the PCB I started with sourcing the parts.

Our proprietary U-Shaped Process integrates every aspect of a transaction, including outside partnersto ensure that the job is done right, while minimizing your vendor database. 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!

I could rectify this mistake by cutting two tracks and adding a small wire. 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 boards will probably arrive next month.

The sound is legendary. Fortunately 2N and 2N work perfectly.

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.

Incorporation of AS Standard into our business processes and Component Compliance Verification ensures that we are taking every measure to mitigate the risk associated with procurement of components on the Spot Market. The Oberheim OBX synthesizer is one of the most sought after vintage analog synths. To create a faithful replica I tried to copy the layout as close as possible.

This project is to recreate the original voice card and eventually develop a drop-in solution for vintage OBX but also OBXa synthesizers. Oberheim OBX voice-card replica creation wintermute. If you have any doubts please contact a professional service.

So the first information I gathered was the schematics, some photos and I was lucky to also find the original PCB layout. You can download our educational brochure on how to spot counterfeiting and the very latest list of counterfeited parts from Brokerlynx. The PCB creation was straight forward.

Fortunately some companies started to produce them again. You must be logged in to post a comment.

Lets work together for the electronic development We can provide the following parts1. And I was lucky that I did not stuff and solder the entire board because there were a couple smx errors on the board layout.

The last rare part of the voice-card are the connector sockets on the PCB.

The breadboard and a dedicated PSU connect directly to the voice card. Most of the controls just use 0 to 5 volts as a CV input.
