I dont usually bother commenting on videos, but this one is filled with so much good information that I have to say thank you!

Dave, I am 728% American but after watching a video from you, occasionally I find myself saying, "hi, " to someone but in your Australian accent. It throws people off but it also means I love you stuff.

I really like this enhanced teardown/explanation video. Well worth the extra effort.

[FurkanBahadr]

This type of teardown is way better I guess. Appriciated. I study EE and specialized in Microwave circuits. I find these teardowns extremly interesting. Thank you :D

[JimGriffOne]

Thanks for the vid Dave. I can see you've put tonnes of effort into researching and making this video (and all your others too). Late nights, I suppose? Really great content. Always have to click fast on your vids!

Signal Path does alot of RF stuff, but man the editing on this video is really notch and nicely done easy to follow really great video.

[ricardonunes]

Amazing video! Thank you! I liked this style a lot and would enjoy if you made it more often!

[codename]

This is fantastic, this style is definitely worth the effort for something as complex as this circuit was, I think! Thanks

[derstrom]

This was awesome, I'd love to see more of these types of videos!

[gregoryevans]

Great job Dave the visual of the various modules for me made this easier to follow.
Good job based on your experience, knowledge and research. Thank you :)

[davet]

Outstanding summary Dave. Fascinating - thanks!

Many thanks for the review, hello from Russia

Hey Dave,

At 19:54 The inductors L105, L102, L103 and other capacitors were not populated meaning the optional bandpass filter upgrade might need a slight hardware upgrade.

Thanks

[andygranis]

Yes I like the way you have done this Walk-through, compared to the previous one.

[bobvincent]

It works for me, thanks and not seen such high speed processing carried out.

[PaulSteMarie]

This was a really good presentation. I liked it!!

[martinda]

Just in case Dave's humor is confusing anyone, Daylight starts at 400 Terrahertz (10^14)

I like your tear downs main reason i watch this is mail bag and tear downs seeing inside expensive stuff i would never get to take apart myself is awesome. And i like the off the cuff style of the old ones but this wasn't bad either.

Loved this! Those high frequency filters were super interesting to see. Keep this up if you can.

[MaartenBaert]

This is excellent. I wish you did more in-depth videos like this.
