I've found a source of these tubes in Vancouver, BC. They are made in England and I'm wondering if english Amperex tubes are OK or better. Thanks in advance. If this is a bonanza, I'll be glad to post the suppliers name and address if that's not a breach of 'netiquette.

never heard of Amperex 6550, it might be relabeled Chinese 6550.

I can assure you that Amperex never made a 6550. For that matter 6550's were
never made in England (or Germany, for that matter...I've seen these offered
too).

The easy way to tell a Chinese 6550 is the hoop for the getter, which looks
like a thick washer. Recently Philips has been offering Chinnese made 6550's.
These should not be confused with the ones they made in the U.S. which had a
straight glass envelope. Chinese 6550's use an "ST" envelope (curved at the
top).

While were on the subject of forgery, I still see a hi-fi dealer in Arizona
offering Amperex JAN 7308 10 for $100. Though when I called him I told him
they were fakes (based on some identifying marks not there), he still offers
them. Also says he can get plenty more (wouldn't that be great if it were
true?) His ad is in Audiomart.

I also saw some GREAT EL34's made by Telefunken...oops...labeled "MADE IN
ENGLAND" on one side and "MADE IN W. GERMANY" on the other. Maybe they got
confused.

Unfortunately, it's becoming more commonplace. ---Kevin Deal

Yes, beware of tubes that cone from unusual sources, like an Amperex 6550.
FYI, there lots of fucking scumbags out there that are re-lableing
Chinese firecracker tubes with the labels of good manufacturers. I've
seen Russian 6V6s labeled as Westinghouse, and Chinese 12AT7s with the
same label. If you buy tubes, make sure you can return them if indeed
they are counterfits. Moreover, threaten to turn the dealer over to the
law for fraud. Big jail-time usually.

I have a set of "Amperex" 6550's and they're identical to some Chinese Gold
Aero tubes that I also have. They even die like the Chinese 6550's.
Amperex - no. Junk - yes. I'd stay away from them.

So did the old American Tung Sol 6550s. The Tung Sol is generally
regarded as the best of the 6550s, while the Chinese copy is no doubt the
worst. I assume everyone has heard the story of the guy who bought a
bulk-pack box of Chinese 6550s, and he found one with a cigarette butt
inside.

Does anybody know how to identify Tung-Sols? I have 2 tubes that have an
Octagon with 6550 printed in the middle.
