I have been trying most of the day from two different systems to gain access to the elektrotanya site to look up TV service manuals. Did theey get shut down? or down for site maintenace? I hate to see it go.

Hi,
i unlocked my T590 with SVOD4 and wrote new ec from lenovo site. Now password is gone but dmi is missing now. So i have to write it back with Thinkpad Maintenace Utility.
I now have newest version of lenovo U1 golden key software (3.5.52) for USB boot stick. This tool starts the Thinkpad Maintenace Utility V1.20.
But i can't initialize eeprom. It says: "ERROR: Written data is unmatch."
So i can't write sn number without initializing it first.
Any ideas? -
The LM358 LM358S-13 consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
Application areas include transducer amplifiers, dc gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems. For example, the LM358 series can be directly...10-07-2024, 04:12 AM -
I'd like to drive LOTS of RG6 drops (i.e., 20?) without having to rewire splitters (they are highly inaccessible).
I can't locate anything mains-powered near the splitters so any power has to come via an injector(s).
So, is it better to put ALL the gain between the antenna and splitter; some gain on each drop AFTER the splitter; or a combination of the two? (Or, a multi-tiered splitter with gain between tiers?)

Good day folks. In another one of my "sonic projects", I got myself a couple of these little pre-made pre-amp boards off Ali (photo 1), mostly to experiment with them and learn something in the process by hopefully combining my modest electronics knowledge and my passion for audio, although I don't claim to be an audiophile who likes to spend thousands on pro audio gear....which itself is often regarded as just snake oil and marketing BS from what I've read. I'll try to keep the wall of text to a minimum so:
The op-amp they came with is an AD828, which the datasheet calls... -
Hi! Hope you're fine! (:
So a friend gave me this unit which had faulty pushbuttons. Sadly I messed things a little up while doing the job.
Here's the schematic hosted:

I managed to repair a vias connecting bottom and top with a bridge. After this sound is back on channel 1.
More saddly I managed to destroy channel 2 by an overload occured while testing (too much volume). Now channel 2 is dead and I'm left with channel 1 who seems to work fine.
As I am...
