Rare! Lot of One Piece 1578 MELZ Holed Anodes Metal Base Tube


1578 tubes with holed anodes, made in 1970's, are the best of the world of 6SN7 tubes, highly sought after by audiophiles.
Produced at 1976 by MELZ.
All tubes are new, never used.
Equivalents: 6SN7GT, ECC32.

The 1578 tubes come with the inscription '1578' on the glass bulb, or without it.
A characteristic feature of 1578 tubes, in contrast to conventional 6N8S tubes, is the presence of large metal fastening elements for the upper mica of the anode system. In conventional 6N8S tubes, these elements are made of mica and are small in size.
It is this feature that is the reason for the unsurpassed sound of the 1578 tubes.
