AC voltages do not vary whether using a solid state or tube rectifier. =
By the way I still have the 5U4 and 5R4. My problem is that the AC =
voltages are high (and hence the DC ones).

Are the rectifiers solid-state or the original tubes? The manual says =
to expect a 12% increase in voltage using solid state rectifiers. =

someone, along the way, may have changed the p.s. to capacitor input,=20
vice choke, in the filter sction??? Regards de K3HVG

During receive, I measured somewhat less than 2 x 400VAC and =

Does anybody recall having measured said AC voltages?
