They won't.

But I was surprised another guy had sold a number of these for such a high price.

I actually bought a pair of these for my Schiit Freya. They were the first tubes that were dead quiet. I have tried the stock tubes, EH and Northern electric tubes. I have not heard any new tubes that I can stand because of noise. I was close to just listening to the solid state option of the preamp till I found these. I would love to find another set of NOS tubes (different from these for testing). From what I have heard so far new tubes are noise makers.

I was not complaining the quality of these tubes.

Glad you like them.

Russian rebrands.

This Ultron was a house brand of Bürklin; they did not make the tubes themselves.

I used to have a Utron tube but I'm pretty sure it was German made , bottom getter looks Russian tho,Thank you

Yes, in true rebrander fashion they sold tubes from many makers.

Hopefully I won't be disappointed

Bought quad for electrostatic tube amp so it will be hard to keep away from them,good deal

As long as you like it, be happy. No need to buy those $300 RCA VT231.

You may want to clean the pins.

You may want to clean the pins.

it's worth touching a hot soldering iron to each pin to reflow the solder.

Can anyone tell me if these metal bases I bought from ebay are the famous Melz tubes? Thought it was worth a punt at the price.
