CA3081 Replacements With Discreet Transistors
Options are really limited for transistor arrays. Emitter is all common together inside the CA and attached to ground. I have them on my website now. I used to use SSM’s, but you ca30081 find those anymore either. Assume all of them from China are a used pull which is probably not tested. Pin 5 and 15 of the CA are grounded so you can use those, or like i did, just find a nearby ground pad that was most convenient.
New and Cca3081 RCA.

See details for additional description. Got the size down as small as possible with zero extra vias.
I thought I needed one of the CAs earlier this week, thankfully it ended up being the 74LS I bought a bulk lot of dead Williams Master Display driver boards from eBay and harvested the s from them. Remove the legs and clear the pcb holes then just straddle and solder a BC across the chip body.
But I think the is scarce.
Desolder the pads clean. View topic image gallery. Let me know what you think. Here’s a Flash Gordon that i did recently. Ghostbusters Pro by Stern.

I couldn’t find a different transistor array to sub in, so i figure 2n is probably acceptable commonly used discreet sub. I could make them available as a DIY kit. But for something like this, reduction of size is important so it fits on all pcbs.
Me too, and having too many vias as well and jumpers. See all 3 brand new listings. Certain page elements may have been deliberately hidden. I wanna breadboard one now and see if that works. I was going to try and do this in a IC socket, but this is way much better!!! But that would make for a neat little package, just hot air the SMD IC right onto a single layer board with headers.
I think the other type of CAX is for common collector instead of emitter. Maybe you could breadboard up the next hack on something like this: All I did was snip off the bad associated CA legs.
Stuff collector and base into the appropriate pins of the CA Went with through hole transistors for ease of assemble. I opened my part drawer and found I was out of the CA Any input is appreciated.
I build a lot of VCO circuits for synths with 2n matched pairs for oscillators. You can probably leave the diode bias unconnected on aground the input and leave the output unconnected and you’ll be in OTA business, unbuffered. I need to order some more of your other chips anyway.

Star Trek Shooter Rod. It’s guys like you that will keep these machines working. Game Of Thrones Gear Mod.
You would get a sheet of blank PCBs, headers, ac3081 2n transistors. No ratings or reviews yet. Wizard of Oz Standard. That comes naturally after building your first few crappy designs.
At least most of them worked, but they’re ugly. My cousin does multi-layer boards. This page was optimised for printing. I love this kind of old school electronics. Ingo, tilting the transistors is perfect. Fa3081 barakandl 2 years ago. I pulled off a hack today.

Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.
