Dynaco ST-70 Original vs. VTA Bench & Listening Test Comparisons - Stereo 70 Tube Amp
In this video I compare the differences between a stock restored Dynaco ST-70 and VTA modded ST-70. Bench tests include frequency response, max clipping power, and THD+N at various power levels and frequencies. I also conducted a casual listening comparison with friends.
My bench test results seem to reflect the results found by ASR. You can find the VTA and Original ST-70 write ups here:
