Does any one know where to find a signal generator program for running on PC.?
just a 1khz sine wave would suffice!!
Thanks

i think there is one on duncan amp tools. i downloaded it but havent tried to use it, as i havent made a probe to attach. when i do make a probe, i will make sure to put a cap on the hot side, to ensure that accidentally probing something with dc on it -
I've been wanting to build a signal generator from an old casio mini keyboard
the flute setting is a pure sine wave
ted weber sells small transformer (less than $5) for making a line out you can plug into the headphone jack
the volume control will give you amplitude
and you have your choice of frequencies

Attached is a 1kHz sine wave mp3. It's about 10 seconds long so use your computer/mp3 player's loop function for testing.-MikeComment

Hmmmm. my last post disappeared....anyways, i don't know what kind of A/C voltages to look for at the various points. I can tell you what i checked so far with the master all the way up
speaker out: 7VAC
EL34 grid: 75VAC
Master vol out: 2.5VAC
tone stack in:47VAC
any clues there?Comment

Well, 75VAC at the grid should be enough to drive the power tubes pretty hard. But 7VAC across an 8 ohm speaker load is only about 6 watts. So something doesn't add up there."Enzo, I see that you replied parasitic oscillations. Is that a hypothesis? Or is that your amazing metal band I should check out?"Comment

I have one, but I'm not sure how to post it for downloading. If you'll email me, I'll send it to you.Originally posted by conisat View Post

pc based dual trace osciloscope AND a stereo programable signal generator with sine square and triangle outputs
I forgot all about this program
My son uses it to "super tune" his guitar
has a lot of nice features on it

I just downloaded it onto this computer and it seems to work with VISTAComment

Has you son checked out G-tune? It's shareware, but well worth the nag screen - especially for intonating.
