CORRECTION; I should have said a blue glow for a fraction of a second with the stock AC cord and one/two seconds with various after market AC cords.
Valve Question?
I have a pair of Cary 2A3 mono-blocks. I know sometimes its normal to see a blue flash when the power switches are initially turned on in the 5R4 tube. Can someone tell me why the blue flash lasts about one second with the stock AC cord, but lasts from two through four seconds depending what power cord I use? Thanks,Larry.
