I am merely filling out my collection and I did not have a 1961 Melz so I bought one when I saw one available. How was I to know I would like it this much lol? There are a couple 1963's on Ebay and they are quite nice, and a friend picked up some 1959's last week. The tubes are out there but you have to be diligent, and take chances. This is not a game for the meek especially when some are $140 each plus shipping. :ksc75smile: Also oftentimes you need to re-solder the pins on the older Melz.

Tube rolling is the ultimate in chasing your tail with expectations of catching it with your teeth. Especially difficult for humans.
ROFL!!

Burn in time for (NOT NIB) NOS 6SN7s? Or are they good to go from the start since they were probably used years ago?
The theory behind burning-in NOS tubes is that heating them helps to activate the getter to remove trace gases which may have formed during shelf life.
But again it’s a theory and not a proven fact but it won’t hurt.

So a few hours or so is probably all it's gonna take if it's anything at all?

Burn-in could be done while listening especially if there is no humming or hissing. 👍

And if prefer to do some burning in, you can do it without the power tube plugged in.

Yup. If it's been previously used and just not played in a while, a couple hours should be sufficient to get it singing again.

Just burn it in normally.
Do not turn up the volume excessively.
And when it ran for 5-8 hours a day, I wrote down the hours until the 50-100 were through.
I didn't let the Lin Lai run for more than 8 hours at a time.
Unfortunately, they need a minimum of 100 hours, but then it's also good.
I was through with it in just under 3 weeks.
Also because it only ran for 4-5 hours of the amplifier instead of 8 hours.

That's part of it when you buy a tube amp, even if it's a nuisance.
I don't believe in burn-in from the socket and all that.
The old method also reveals whether the tube is working properly.

But in the end, everyone does what they think is right.

And I was still shy admitting that am still keeping my Matchbox car collection 😃😃
I still have a Corgi collection: one in it is the 007 gold Aston Martin DB5 with the bullet shields etc.

Well I admit it's hard for me to let go, my collection even survived my kids playing with it. 😃

Woodstock is part corgi.

After 12 hours of running, a new amp with a Gungnir source is sounding pretty amazing. Listening to a Melz solid plate from 1958 with a Tung Sol 5998; this combo is phenomenal IMHO. Listening with Focal Utopias. Next up is a Melz 1578 from 1961. For me the Melz have no rivals, if you get the right years.😸😸
