[R-390] Solid State rectifiers vs Tubes

[Scott, Barry (Clyde B)]

List,

I was looking over the changes to the HP200CD audio signal generator and I found where they went from solid-state rectifiers to a tube rectifier.  That seems rather odd to me.  Why would they have decided to go back to a tube rectifier?  The change notice included distortion figures.  Would a power supply configuration with a tube versus solid-state diodes have lent itself to a cleaner signal?

Thanks,
