I wish I could get your thoughts on the sound of my mentioned at the end of page 1 since you are picking the little brother to my pride and joy tube, lol! (1963 Amperex Holland 7308 w/ Bugle Boy logo)

I would give one word of advice on purchasing any of the pinched waist tubes out there. Do not rely solely on pictures to analyze the tube, it's very easy to make a tube look like a pinched waist without even trying to deceive the buyer. It has to do with certain camera lenses and the angle the pic was taken at. So if you are going to drop that kind of dough, either see it in person or buy it from a reputable tube retailer instead of Ebay. That is one of the few times I would discourage using Ebay. BTW: you have 3x more Pinched Valvo's in your single picture than all known 7308 Holland Bugle Boys in existence!

https://zosoncsu.com/2017/09/11/1963-amperex-holland-7308-w-bugle-boy-logo-first-one-ever-verified-by-audiotubes-com/ Never before seen 7308 Bugle Boy Tube: Amperex (Holland) 7308 labeled (eqiv. E88CC or better) w/ the Bugle Boy logo (w/ production & date codes: 1963). First 7308 Holland Bugle Boy Ever Verified by AudioTubes.com in 20 years and counting. I am gauging interest to see where people would put the value of this ultra rare and amazing sounding tube vs. other rare tubes. However this is a different caliber of rare even to say a CCa Siemens or the famous MiniWatt line, those are just hard to find due to cost at time of production resulting in low volume. The tube I have which still tests out at 77 out of 100 on my 82A tube tester (in line with orig Ebay test results in link above); being made in 1963 and it found its way to the US through Canada. I found it on Ebay and had a strong suspicion this could be a diamond in the rough (ugly metallic Tektronix Sticker rating) at purchase. However I had to take a chance on it and pay the premium for an Amperex 7308 Holland ($70-$80) testing about 85% with no shorts or leaks present. Screen still in good shape, overall the tube itself was nearly perfect except that ugly sticker.. I did indeed notice the Bugle Boy logo showing barely at the bottom of the Tektronix sticker and did some research. AudioTubes.com lead me to believe this had to be a fake, since all they had ever seen claiming Bugle Boy + Holland 7308 were always fakes from Richardson Electronics dressing up 6922's. This is why the fakes never have 7308 batch codes as you'll see in the photo (VR = 7308 for 1963). The Bugle Boy logo was older than the Tektronix sticker which meant it wasn't fake, AudioTubes.com only challenged the 7308 status which I then countered with various photos showing the VR code using both enchanced and non-enhanced photos. At this point Brent verified this as the only one ever seen in 20 years of AudioTubes.com! I was offered $200 in 2015, but turned it down right after Brent from AudioTubes.com verified the tube as a real Bugle Boy, the first spotted online. $200 is about what a CCa brings, so what would you all value this tube at?
