Something's Mything from that statement. Like... A sneeze.
I'll get a life when it's proven and substantiated to be better than what I'm currently experiencing.

- Upgrade the Media PC's storage and bring it forward into more everyday use. (Truthfully It's a crappy/scrappy dual-core w/ built in 5.1 and an antient video card that outputs SVHS to a big ass'd CRT TV...) W/ an video card upgrade I might go HDMI... :o

I'm soooo behind the Cutting edge, well, it actually IS funny...
You know, I only just got rid of my CRT TV last summer, when I moved... My dad gave me a flat screen TV a few years ago, but I had not taken the time to do the switch. When I moved, I finally set up the flat screen TV in my new home. I put my old TV up for sale on Kijiji, and someone was interested. But when I brought it to him, it turned out that the old TV had a scratch on the screen. So he wanted to forget the whole thing, but still pay me something for my fuel for bringing the TV to him... I suggested he just keep it anyway, to use it until he could find something better. Honestly, I had never even noticed the scratch before, so it obviously wasn't affecting the image all that much... He did end up keeping it, which is a good thing, because there just wasn't any room for it in the new house...

My cell phone is a LG Stylo 3 Plus... model came out a year ago, and is fairly low end... And I am NOT using it to "keep connected" to all the social media...

My cable box is an old, outdated one, one that is no longer supported by the cable company...

My laptop, until recently, was an old Acer Travel Mate that originally came loaded with Win XP... (I only just this month updated to a refurbished Dell Latitude 5285 2-in-1 convertible... 8GB of RAM, a Core i5 7300 CPU, and a 256 GB SSD)

My computer is an AMD FX 4100 processor... it's already several years old (CPU-World says the series launched in 2011...)

My DSLR camera model (Canon EOS 40D) came out in 2007, which is rather ancient, in the digital camera world...

My truck is a 1991 GMC Suburban...

My bicycle is a fairly recent vintage, however... 2012, in bicycle terms, is not all that old.

But yeah, you're not the only one behind the technological curve... :mrgreen:

Had a bit more fun with a simple refurbishment job recently. At the flea market a couple of weeks ago I came across a KLH Model 200 table radio... a two-box stereo AM/FM system that Kyocera built back in the late 1980s when they owned the KLH brand name. The seller wanted $20, said that it mostly worked but that the volume control wasn't reliable. For the price I said what-the-hell... I've been wanting a decent bedside radio with an alarm-clock function.

It did need some work... a bit of epoxy inside to repair a broken mounting clip for the front PC board, and a good cleaning of all the controls for starters. This didn't fix the volume problem... the sound kept cutting in and out... and I eventually figured out that the output-muting relay had worn-out contacts.

A new relay arrived from Digi-Key, I soldered it in yesterday evening, and clean sound has been restored!

I don't know if I'll do anything to the speakers. They're decent little paper-cone pleated-surround drivers, about 4", not really showing any signs of age, in mostly-sealed compartments made of thin fiberboard. I'm sure they could be improved but I don't know if it would be worth the time and trouble... they serve the needs pretty well as they are.

Well, I couldn't resist the urge to fiddle. After listening to the KLH for a while I decided that the speakers probably deserved an upgrade. I ordered a pair of 4" full range drivers from Parts Express... some positively-reviewed poly-cone house brand (Dayton) whose specs suggested that they would work OK in the small KLH cabinetry.

Lucky choice... the results are very nice indeed. Installation was easy... they're basically a drop-in replacement. The sound is clearer, more balanced and musical... no deep bass of course, but what's there is clean and boom-free. The system now sounds like a compact stereo music system rather that like a clock radio with pretensions of grandeur :D Our local classical-music station just finished playing "Concerto Fantasy for 2 timpanists and orchestra" by Philip Glass... a very nice test that the modified KLH passed without any distress at all.

These inexpensive ($13 each) drivers are good enough to make me wonder how they'd sound if you put one or two of them into a quarter-wave transmission line enclosure. Might make a very nice music system for a small apartment or dorm room.

I've been kind of laying low on Audio/Video interests as I try and ramp up the career side of things, time to 'Level Up' as the kids used to say.

Still, I have a few things on the back burner, and it's always good to hear from real people and their real life chances they took and how it worked out.

Danka...
