Virtual variac switching question ?

[5150canuck]

I am new to this site as a member, have read your postings over the years with all the great help you give to each other...


I notice the 68 12 series spec said the following statement ....

*Virtual variac switching is incorporated into a three position standby switch to retain vintage accurate layout and appearance. In the center position the amp is in standby, in the up position the amp operates normally (approx 495V), in the down position the amp delivers only 400V to the tubes. This is to simulate using a variac set to 95V AC input.

Has this feature always been there, would a head built by George in 2009 have this feature ?

Thanks

Yes, the virtual variac was available in 2009.
