My DIY Audio Scope so far (will update)

It is a well known fact that girls cannot resist a well dressed man with a Wurlyscope.

If there will be a second release put me on the want list please.
I'm sure there are others too.

Add me too

A great pickup line that works every time is “Hey baby, do you wanna go back to my swingin’ bachelor pad and check out my Wurlyscope?” They can’t resist.

But that's because they think you've got more money than sense!

A potential advertisement for the Wurlyscope:

Like many people of achievement, you’ve probably postponed some of life’s special pleasures on your way to where you are. If so, this is your time - and the new Wurlyscope is the perfect way to show to others that you have arrived. Go ahead......you deserve it. Also available in a special 24k Gold Plated version for those who only want the best.

I cobbled together two videos of the Wurly using SQ test tones generated by Malcom Lear's program with the Involve SQ and the Space & Image Composer.
First is 8-position, then X-axis, y-axis, and z-axis
I forgot to center the output balance pots on the S&IC before filming, so the center front tone is little off center. I almost never power it on since I haven't got it recapped yet, didn't want to do a retake. Also, just ignore TV and awkward breathing in the background.
Edit: Added video of Fosgate 101a, I attempted to adjust the balance pots this time but still not perfect. Unfortunately the the 101a has muddy sound but is still working in all channels, also probably could use service.

What's your opinion of these results between the two (does the S&IC lock on more accurately for most parts?)

I would say both of them lock solidly and accurately direction wise, but the Involve seems to have more ambient sound from the opposing channels, the Tate only sounds awkward with certain stereo material with the seperation pot all the way up. Btw I just realized it was at about 85% in the video. The Wurly also seems to confirm this.

I wonder if i should start another thread about the AFV JCQS-440

I used 1% precision resistors through all circuits to get accurate measurements.
There is no trim-pot adjustment inside.
I'm happy to see it in action.

Might as well at this point. This thread had a good run. It’s only right that the Wurlyscope have its own thread .

Thank you doity!

Maybe one of the mods can move my post over to here

Maybe a Copy & Paste is simpler

Thanks for the video, but I'm having trouble interpreting the results from your description of the test tones. I guess the the eight positions are supposed to be C,R,Rc,Rb,B,Lb,Lc,L (although I'm not sure I can identify them all) but what do you mean by the x, y and z axes in SQ?

Yes, the first part is fr, cr, br, cb, bl, cl, fl, cf. The next three rotation tones are in SQ, but I don't really know exactly what they are doing, would have to ask Malcom since he created the program that generated these tones. They also look cool on x/y mode on a standard 2ch oscilloscope.
Here are the tones used in the vid:

Hello Scopefans,

#6 ist working in Germany, Europe.

Thanks to Wurly for this excellent device.
It is a pleasure to see the music and enjoy the events in the half-dark.
I have given me a little delicious wiskey. And I may say that I could not go loose (but from the drink already) but I have heard a title by one.
My family already had me on the missing list

Here is a visual impression of my music room with the scope

Thank you Wurly

Hello Scopefans,

#6 ist working in Germany, Europe.

Looks like your part of Germany has been particularly badly hit by the appalling floods - I hope you and your family remain safe. Best wishes to everyone there.

 

[bevergerner]

Thank you - yes here is everything ok.
But 200km or 120 miles from here ist ist undredible, it is a desaster. Helper compared it with a tsunami. The Chancellor said that there is no words in our language for what she has seen.
Only a little removed is all destroyed ... are life lost ... do not have people anymore.
Thanks for the good wishes and the sympathy. We should always remember that it can happen anytime in any place of this earth.
There is so much distress and misery worldwide.
