I enjoyed a little "garage find" this weekend. Not an equipment find - not even really a garage find - but a magazine squirreled away for decades.

I've been writing a series of online articles about old computers, mostly eight-bitters from the 1970s. I actually hoped to do one about every three months but I kinda went crazy on the first one - the Sym-1 - and so the second one was delayed. But I finally got around to writing this weekend, and uploaded an article on the RCA COSMAC ELF. In the months to come, I'll write articles on the Altair 8800 and the Inmos Transputer.

The ELF was a computer project described in an article written by Joseph Wesbecker, published in the August 1976 issue of Popular Electronics. A photo of the computer is shown on the cover of the magazine, and I reference that in my online article about the ELF.

So now to the point of why I wrote here. Go to the RCA COSMAC ELF page and find the image of the Popular Electronics August 1976 magazine. Click on that and you'll get a PDF file of the whole magazine. Then go to page 14.

It's an article about the differences between tubes and solid state. I had to post that here 'cause we still talk about the very same stuff, almost 50 years later!

Beats me but I sure dig my tube gear. But same with my ss gear. Just not as fondly. I didn't know that tube gear was as prevalent as it was in 1976. Like vinyl and phono it just couldn't be made extinct. Maybe because of us baby boomers, but like Pandora's box it's out there affecting younger generations. At the end of the article is an ad for a dot matrix printer. Damn thing looks like it's got a Briggs & Stratton motor on it. Digital really has come a long way from it's infancy.

P.S. Enjoyed looking at your "day job" work, You're on another level Wayne, what you do. And your family photo's.

Hi, As long as there are tubes and solid state gear they will be talking about it. I have a considerable amount of each. In my main system there are 4 Oddblocks that provide the muscle to the speakers. But there is no way I would replace the solid state electronic crossover that splits the sound to the amps. It would take 50 tubes and not be as good. Same thing on my main turntable. I can't even imagine trying to power the motor (an ex Dual 701 ESD1000) with tubes. The heat alone would require its own cooling system. The issue is not so simple in other parts of the system. I have tube and solid state phono preamps. The SS ones gather dust. FM is done by a really slick vintage Sony tuner. Tiny thing with only one sealed metal box in it. The thing made the "B" list for Stereophile. Incredible sensitivity, sound etc and OBTW gets HD FM. No way I would swap that for a tube unit. It would be a serious step down.

Now that we opened Pandora's box... the argument of discrete SS components vs IC ones. That is nearly equal in pros and cons. It includes the thoughts of some negative feed back, none or lots (as with ICs). Chomp on that one a while.

My overall take is that (one) there are many ways to do most things (two) each of us has to decide what works best for ourselves. Rolling Eyes


Good Listening

I'm pretty sure that each of us (regulars) here on ART is in one-accord on this. But I was just surprised to find that amplifier article, long lost in my mind. I just had to mention it here, just for fun. It was as fun to read as the computer article I dug it up for.
