Tubes: Quad 6550's , 12ax7

[spellcaster]

Just bought a vintage Sunn that has a quad of newer 6550's and 3 12ax7's installed. Before I bought it I had a tech look over the amp and test the power tubes.

They test:
47.3
46.7
50.5
52.2

Not sure what they are since the logos are not there for some reason but they say "6550 C" "Made in Russia" from what I can tell they look like Wingded C's or Svetlana. Maybe some one here can confirm them from the photos.

Tested the amp and they sound great but I'm looking to put KT88's that originally came in this amp and wanted to see if any one needs these.

SOLD

Also, Have 3 made in China 12ax7's will throw in for free with the 6550's or all three for $20 shipped

In the Sunn PA

Hi, very much interested. How much with postage to Australia?
Only condition on sale being, can you post a larger photo of the one right of centre in the top photo? Only concern is that it looks like the getter might be failing.

Just looked them over again very closely and fired them up. Sound and look great! I think what you might be seeing is just strange reflections or photo distortions but add some more photos.
From what USPS is telling me, shipping to Australia is $25 first class international or $44 for Priority. Thanks!
