I had some time to myself this weekend so I thought for S&G I would hook up my bias probe and grab some quick readings and share them with The Board.
Plate Voltage was measured at 452V.
MESA STR-440 "YEL" (the tubes that came with the amp)
V8 = 26.2mA (39.5%)
V9 = 33.4mA (50.3%)
V10= 34.4mA (51.8%)
V11= 24.9mA (37.5%)
MESA STR-440 "GRN"
V8 = 33.1mA (49.9%)
V9 = 43.4mA (65.4%)
V10= 44.5mA (67%)
V11= 32.3mA (48.7%)
SED =C= SV6L6GC ("Mesa Grade")
V8 = 30.1mA (45.4%)
V9 = 35.6mA (53.6%)
V10= 34.7mA (52.3%)
V11= 31.7mA (47.8%)
Your typical Mesa readings.
