I did find 4 matched philips/amperex holland made fom 1963 - 1969 here in sweden to a really good price so i brought them and just put them in.
But when i start the pre amp (C500T) the tubes flashes like a normal light bulb for 1 sec and then turn green. is this normal? It did not do this with the gold lions.
Everyting else is normal.
