Default Re: AVO VCM Mk 3.

Thanks for the quick reply Martin.

First the MkIII. EL84 fitted. 35mA

aV 267V ac.
g2 146V ac / 120V dc
g1 3.98 ac / -8.22 dc. . mA/V possition and nulled, 10.22 ac / -14.57 dc.
h 6.30V ac.

Now the 163. EL84 fitted. 55mA
aV 197V ac. 200mV ac.
g2 159V ac / 129V dc
g1 4.24 ac / -3.92 dc. .
h 6.39V ac.

Quite a difference with the D.C. grid volts?
