No time to post photos now, but I'll try to remember to do so later. I suck at describing tubes, but these are all gray between the mica(?) plates, and have the inverted UFO getter which has the single support. The "UFO" is at a slight angle. I recall from the old Lyr tube rolling thread that there was some confusion about what the "shield" is. I will say that on the top mica(?) plate there is a long, low gray piece that extends up perpendicular to the plate, just below the "UFO". Think of a rectangle that is wider than it is tall.
I'd refer you to the eBay listing, but the seller used a pic of the '78 Rockets, which have a different construction (at least they were honest enough to state that they used a stock photo that may not match the actual item). Mine are clearly 1974s. Irresistible at that price.
I don't want to judge them yet, as I think they really need to burn in. I did listen right after I rolled them and heard a lot of room for improvement. Eight or nine hours later I thought they sounded better. After a couple more hours today, with different tunes, better still. I like to give whatever tubes at least 100 hours before some seriously critical listening. Still, the first pair is very promising, esp. with the HD 650s.
These are very good tubes, I believe I rated them 6th on my ranking of the '70s Voskhods. And it sounds like you got a bargain, especially if they were well matched. The ones I'm looking for have a single wire the runs up from the shield to hold the getter, as the 'getter post'. These are exceptional beating every tube I have compared them against. Including the '75 Voskhods with gray shield and plate getter post. Including those wonderful USN CEP 7308s I just sold. Only trouble they are so rare. I '73, '74, '75 versions of these wire getter versions, which all sound good. But after weeks of comparing again each other and the USNs, the ones that had the magic where the '74s with silver shields. They added this level of depth and timing to the already excellent detail and musicality of the the top Russians.
My hunt continues. It's so hard, as you mentioned, the pictures don't match what these Russian ebay sellers send you. Good luck!
