2 Siemens 12AU7 ECC82 Silver Plate Tubes

Tested on a Hickok 6000A
1250=Min 3000=Max

Tube 1: 2025/2000
Tube 2: 2000/2000

These are some amazing sounding tubes. The highs are very extended and have a beautiful sparkle to them. Not bright at all. The bass has excellent definition and speed. Tonal textures are spot on. Probably one of the best sounding 12AU7 for definition and clarity.

I wanted to keep these in my collection, but I just can't right now.
