Some cool-sounding, made-in-USA tubes...

I've been messing with 7868's, 7591A's and even rare and hard-to-find 7355's lately.....and researching the cool uses for them. Lotsa NOS ones are around and they are making some of them again in Russia.....the old ones are mindblowingly killer-sounding. The new-production ones have about 80%-90% of the vibe of the old ones....they're almost there. The 7868's are about 22 watts rms per side in Fisher amps from the early 60's like the venerable integrated amp the X-101-B model with two 7868's per side. In the X-202-B there are 35 watts rms per side with two 7591A's per side. Some really cool Sansui tube amps used them too----those old Sansuis have some killer-sounding output transformers too! Also check-out Hashimoto hi-fi output transformers for extra-rich, musical warmth....but beware: $$$! And I have been messing with the interestingly rare and weird 7355. They had made Fender amps with this power tube in a small batch of blackface Dual Showmans in 1963 but the more powerful 6L6 opted as the choice for the production models........they're really hard to find...but they would make for some cool low-wattage amp projects---right in between 20w-40w rms..just loud enough to get you into trouble....but not like the Ampeg Coliseum I used to play through..or thought I was "playing" through....lol.
