Someone tipped me about the manufacturing date on the etched note of the tube.

The 1578 that I got was made in 1980.

The 1578 that I got was made in 1983 not 70's.

8n6s Nos tube was made in 12/78.


Even without 1578 notation, some tubes are still pretty good for the price.

After listening to 1578 Melz, I am back to Nos 6n8s tube made in 1978 that I got quad at 46$.

By the way i got my first serious audio system on 1978.


What a coincidence.



This is a steal.

It sound musical with good balance of full bass and sweet treble.

Jump at it before they run out of this batch.
shkong78,
 
I have a pair of Melz 1578 tubes. Can you please tell me how to check for date of manufacturing?
If you look for etched sign in the middle of tube, then you can find the year like 80 or so.
