You had to bring up the "Metric" thing again, didn't you. ;D
Great stuff. Thanks for sharing!
there are some wonderful illustrations in those audio books! good info too. thanks for posting.

Art, you were reading my mind. I'm already downloading a bunch of these for etch images. New contest? :icon_twisted:
Thanks Jimi!

1) Thanks, Jack. You're a pal. :icon_smile:
2) Hoochie MAMA!!!
3) The younguns here should go to that site, called up an issue from the early 80's, and flip through the pages at the back of the issue to get a sense of the prices and availability of things at that time.
4) Thomas Henry has a nice little article in the July 1983 issue on using transconductance amplifiers. And I imagine somewhere in that archive is the Mod Box construction project from Jack and Thomas.
Wow! Hey, maybe this e-lectricity stuff is going to be more than just a fad after all.
A lot of the old books and articles ought to be interesting. Let's see who can be the first to make a fuzz box using a spark gap generator. (I'd say use a Tesla coil as well, but I think someone already made a plasma speaker, which kind of looked similar, sort of, kind of.)

There are also some schems for guitar (2 fuzz and amps) from the same website: http://www.rsp-italy.it/Electronics/Kits/index.htm

also some tremolos and guitar preamps and stuff... i downloaded all of 'em!
speaking of mad old nikki tesla, I read somewhere (http://www.diystompboxes.com/smfforum/index.php?topic=70160.0 reply #5) that R.G. created electricity, and was wondering if tesla ever met the great man.
all i can say would be i'd like to be a fly on the wall to see that. :icon_biggrin:

Negative. I've seen that datasheet. I've repeatedly sent requests for information to Toshiba Canada, USA, and even Japan, without ever getting a response. Just sent another one. :icon_evil:
This should keep you guys reading for a while:
http://www.tubebooks.org/technical_books_online.htm (http://www.tubebooks.org/technical_books_online.htm)
Note: This big ol' pile of electronics books includes the Radiotron Designer's Handbook, 3rd and 4th editions.
This should be a sticky thread.
a public domain copyright free books and articles sticky thread would be awesome.
*edit* or maybe a sub forum? to organise tube, transistor, op amp, digital etc...

it's fascinating comparing the style and wording of the snake oil advertisements from the 1919 electrical experimenter magazines and the 1980's radio electronics ones... progress?
The TA7125P was a vca in a 7-pin SIP. You've probably already seen this application, but I'll include it here for reference:

Yeah, Jack, that`s lifted from the Japanese Guitar Synth schematic. I`m intimate with it because I had it on the bread board about a month or so ago. The thing that throws me though, apart from the fact that it`s labeled as a VCA on the schematic, is that the ONLY info I`ve found on it is the descriptor «Ton Control». ???
That`s why I was hoping the a datasheet would clear things up. Even the TA7120 (7 pin SIP), which is listed as a VCA, doesn`t match up where the pins are concerned.
Think I`l write a form letter, and start bombarding Toshiba into submission. :icon_lol:

Metric buttload = ~475-480 liters
Imperial = 126 gallons.
It's based in a unit of measure for wine, so in terms of weight, it's about 544kg, or 1,200lb.
;D

A fair amount of the audio-related stuff is taken from Pete's fine site.
One in particular *can't* be from anywhere else: the original is hand-signed and I know the full history of that scan.
I don't think either Pete or that scan's originator really cares, though Pete does ask "please contact me for permission".
^Wow!
