Fantastic information and demonstration it'd be interesting to see some of these popular Amplifiers being used today on same test...of course without names or finger pointing more of an example of what's commonly being used, thanks for sharing

nice work. That SB 220 is clean as well. A clean signal gets out better ! Peek watts means nothing if distortion . Nice showing the wave forms. Starts with a clean radio . I had some tube amps to fix that where just driven too hard to long and tube flash Then lots more parts burned up. Watch for them Cheap China tubes like 811A or 3-500Z .They known to flash over. get good tubes like Penta Labs or RF Parts ones. Replace 811A with Penta 572/B . Some junk 8877 China ones on eBay . The Russian tubes are real good and getting hard to get for some. 73

Penta Labs tubes are made in China, RF parts are made in China. This might be news to you, but just because the company selling them is in America, doesn't mean the manufacturer is. I guess you can keep believing those are American tubes if it helps you sleep, but they're made in China.

I wanna incorporate a 2 tone signal in all my future builds just to show what the amp is really doing with the signal. Otherwise lots of IMD splatter will make any watt meter happy.
