![]() This has happened in one PC mother board and in the power supply of a pricey Tektronix 2465B oscilloscope from the early 90s. They have shortened and / or leaked their electrolyte and have caused excessive PCB corrosion beyond any repair. ![]() 12 PC-motherboards including an Amiga 600. SMD Ta-capacitors were the culprit of 3 major defects in approx. ![]() And my own statistics show that Tantalum capacitors can pose a real problem. Some background here: I have been "tinkering" with home computers and PCs since the venerable Commodore C64, say the mid-80s. Good Day, Hi nctnico, well, I am a big fan of the "Dont' fix it if it ain't broken"-theory in general. I will provide a brief write-up of this next week (in the Other equipment section) I have turned an old PACE Tweezer soldering iron into one which I can use for the re-capping job.Gosh, our dear catalogue dealers such as Conrad, Reichelt and RS Components are selling these for high prices these days. High-reliable cap types where possible, manufactured by AVX and other brands. I have ordered Ta-capacitors to match - all sourced from a reliable local eBay seller. I will re-cap the PC motherboard and probably the TLA7N4 plug-in.But I still have some here bought 3 years back. I did not expect to ever deal with 3.5" floppy disks again. As I am not sure if the TLA715's mother board & BIOS supports booting from an external USB memory: Prepared a Windows 98 start-up floppy disk.Two partitions at 60GByte each shall be plenty. I have used an external USB-to-IDE adapter and formatted and partitioned the SSD.Purchased a standard mSata to 44-pin IDE adapter & a mSATA 128 GByte SSD.In the mean time, I have not been lazy, but finished the following in preparation: Ice-Tea: Thanks for the offer, but the included TLA7N4 plug-in module shall be more than enough for me. I will share a few details later - and I am keeping my fingers crossed that the unit will arrive in good shape. Well, finally, it is in transit to Europe at this point. More than a week's time was spent for ground transportation and prep. Good Day, I am very sorry to hear about your loss - may your friend rest in peace. I will provide some irregular updates here, so please have some patience. I intend to control the TLA715 remotely from a standard laptop PC via LAN. ![]() Then I will clean the unit and upgrade to a solid-state disk, install MS Win XP OS and the TLA application SW release version 5.1. I plan to check the hardware for usual failures (replace capacitors, if necessary replace the PC motherboard's CMOS-battery etc.). So, I just wanted to thank users David Spicer, nctnico, TerraHertz for their hints, and most of all TiN for his superb work and lots of very useful information such as Good karma on you, chaps. That would have been an alternative unit for me. But, of course, a few days after the above auction, a nice TEKTRONIX TLA5201 in apparently good condition showed up on epay. So, I was glad to find a reasonably priced TLA715 after some time. I have followed several auctions and my eBay watch list was full of alternative items - as I have absolutely wanted some probes to be included. It does its job, but it lacks of features such as conditional triggering or the like- I wanted to share my enthusiasm with you T&M equipment addicts here.: I am currently waiting for my TLA715 to be shipped over to my home here in Germany scored that from eBay. I am using an inexpensive "USB-box" Logic Analyzer manufactured by IKALOGIC for I2C/SPI debugging. The 1662A was fine for most jobs, but it was large, its memory was limited to 4k and its X-Windows GUI was simply out-of-date. Background: I was looking for another logic analyzer for some time, after I have sold a HP 1662A "boat anchor" about 2 years ago. Good Day to the group, I have been "passive" in this forum for quite a while, but decided to get out of the rut now.
