Tube Sound Comparison - ECC83 VS ECC808 (VALVO)

Comparing ECC83 with ECC808 Hope you enjoy this video. and if you do subscribe ! :) ECC808 info from tubemuseum.org "The ECC808 is a low hum, low microphony and low crosstalk dual triode for high sensitivity AF amplifiers, especially for two channel stereo circuits. The static values of the ECC808 are practically identical to those of the ECC83. Unlike the ECC83, however, the ECC808 is only intended for parallel heating (6.3 V / 0.34 A). In combination with a more practical socket circuit by improved shielding and better cathode isolation, a particularly high freedom from hum could be achieved. (Ripple voltage at G1 approx. 4 μV with pin 4 at ground.) The microphony resistance could also be improved by a factor of 3. Due to the good shielding between the two systems, loudness and clarity controls can also be arranged between the two stages without difficulty in the case of cascade amplification. With two-channel amplification, a crosstalk attenuation of -50 dB at 10 kHz can be achieved."
