Good day,
A long time ago I bought 60 pieces of the D3a 7721. The idea was to use them in a phono (RIAA) amplifier, and have more than enough spares, but I do not think this will ever happen. So I am putting 50 pieces of the them up for sale, the whole lot for 1250 Euros. Is that doable?
best regards, Erik

At 25 euro each is easily doable if you sell them in lower quantities like 10 pcs.The actual ebay price is completely unrealistic.
I'm absolurely sure you can find a guy able to offer all of the money you asked for, but that is not really advisable for the usual diy-er while true salesmen that make millions from luxury products usually like a 100:1 profit margin.Pronably few still remember the ec8020 ebay story i can't imagine ANYONE paying 1000 euros/piece even though ebay pretended it was doable.Actually i'd buy proof of any ec8020 sold for 150 euros /pcs ...
As you are here you should probably talk to Jan Didden to sell them through its network as spare parts mainly with a small profit, but I don't see him making huge money out of 50 pcs that also need transconductance matching .

Hi,
What you are saying sound reasonable. Do you want 10 pieces? I would indeed prefer that they end up at a DIYer than at a salesmen.
I can also test them for transconductance. I even have a curve tracer (utracer), but would need to find the motivation to match them.
Curious, I just saw that the EC8020 is more than USD 2000 at ebay. Wow!

I bought 10 from Germany on ebay in 2017 for 17euros each.I have enough of them, thank you!
Ec8020 price is in the same ball park as 6000 bucks for a Nakamichi ZXL...while actually nobody's willing to pay a mere 1000 bucks for one.Just because there are a few pieces outhere the owners wait for a museum to buy them..They probably replaced all the capacitors 10years ago and put those decks on a shelf waiting for their next recap.If they start using them the tapeheads and pinch rollers will wear out and they are basically impossible to source.Anyone willing to buy a nak deck like that is a knowledgeable person and knows what to check for and that those decks will hardly sell for more than 1000 bucks to a different owner .Just 12 years sgo nobody was willing to pay 500 euros for one...Mechanics wear out, electrolitic capacitors dry out, rubber belts, idlers and plastic gears degrade...nothing is really immortal.
One more thing...tubes aren't usually specified to have the same parameters for more than 50 years even if unused because noble gases go through glass or get inside tubes near the pins that can also get oxidezed over time and the tube vacuum cannot be preserved indeffinitely. They may still be ok today and completely useless by 2030... Anyone who bought a new chinese or jj cheap ecc83 knows its emission is more powerful than that of an older mullard ecc83 even though the mullard ecc83 will last longer if you start using a nos one today .That is because the vaccum inside the old tubes is lower, but the fillament and the cathodes of the old mullard was better made not because the original mullard ecc83 emission was lower.Noble gases don't burn the fillament but help ionising the tube which fights emission. So tubes aren't really like wine...They don't necessarily become better and more valuable with time.
There are too many delusional guys running the world's economics unfortunately.

Thanks for the PMs. A long time member offered to buy the 50 units at once, and I prefer that.
