hey, but with the harmonics, there's way more there than meets the eye.That's all there is? Nothing more?? I've lived my entire life for three lousy square waves?

Cute. Now do this animation with the Carver square waves.
Okay, NOW they've shown up, thanks.You can't see 'em? Heck, I even see them in your quote of @paulbottlehead's post (?!).
I disagree. ;-) At 1K you really should get a dead straight top, maaaaaaybe a little ringing at the leading edge. 10K looks very wobbly, 100Hz is very poor, way to much slant.I see the images now. Not all that bad. This is for the factory bought amp?
But I wanna see 30Hz at 20 watts.
Let me tell you a story about the car parts shipped from the East Coast on Boxing Day that have been sitting in Minnesota for almost a week, also thanks to FedEx. Seems there are issues with timely deliveries right now.The factory assembled amp has been sitting about ten miles south of me since the 29th of December. Thanks FedEx!
Kind of points out the difference between audio (not essential to life) and nutrition (definitely essential to life).What's really disturbing is there is also a Blue Apron box of food in the FedEx system that has been sitting somewhere for even longer. I definitely will be refusing to accept that one!
Yes, lightweight was always a marketing point. My observation was that the amount of effort required to remove the covers (de-soldering things!) made me wonder if that was done to prevent casual inspection. I don't know how hard it should be but I wouldn't have expected anything more than screws.According to the promotional literature, the small output transformer was a bragging point. If they had wanted to conceal it, they would have potted it.

Makes me wonder if along with the light weight as a selling point if they had also touted that they were using output transformers rated at 15 watts if it wouldn't have scared people off. I mean hell, I've owned Carver SS amps before and I always found the marketing hyperbole a bit much. If my now defunct Cinema Grand had said that it used Adamantine Steel in the tranny I probably would have bought a Bryston (and it probably would still work).
I was giving a big benefit of the doubt to the Carver amp. I'm surprised that even passed a square wave. Let's be nice to it until it really screws the pooch.I disagree. ;-) At 1K you really should get a dead straight top, maaaaaaybe a little ringing at the leading edge. 10K looks very wobbly, 100Hz is very poor, way to much slant.
Here's a 20 year old Jolida 40wpc I recenty tested, at 60Hz and 10kHz. A little ringing on the top but that just keep things lively, IMO. ;-)

How about we place a questionarreHello Jim!
Why don't you and Bob have a talk and then send a production unit over to Amir for testing..?
Since I'm actually interested in these amps for myself, it would clear the air, so to speak..
That will always happen as it is now on a few Carver related sites. Some sites are reporting on this thread as people going berserk and are offering many explanations on why the measurements must be wrong or that the Carver camp kits were a different design.3. Listening to the amp will be pushed rather than a science based approach
Well, Dave Gillespie over at AK set something of a standard with his Heathkit tests. The old rule of thumb (according to 1950's articles about Williamson oscillation issues) was .05uF across the load at 10kHz without the square wave collapsing indicated "good enough" HF stability for the hobbyist. Dave tends to shoot for .2uF across a load as "very stable."How much capacitance would you like me to put across the speaker terminals?
Actually, maybe it's better that they point or link to this forum so the context is clear, rather than just grab them, don't you think?And do you mind if they repost your square wave shots?
That's up to you.Actually, maybe it's better that they point or link to this forum so the context is clear, rather than just grab them, don't you think?
