Back in the day when I was listening to 408A's, I found these Philips Miniwatt TS62. However, even though these carried the Philips' label, I am quite sure Philips didn't manufacture them. The characteristic seams in the glass are missing and there are no visible etched manufacturing codes. My WAG is Philips contracted with Sylvania to make a deluxe 408A for the European market and these are the result. Anyway, as best as I can remember, these have the same sound as the Sylvanias. Nice tubes.
