One thought on “Siemens ECC85/6AQ8”
This is a great tube from Siemens, and while it is not very well known, it features the same pinout as 6DJ8/ECC88 and 6CG7 tubes. It is important to note that the Siemens ECC85/6AQ8 is not a direct replacement for either of those types, however, I have tested it in multiple applications designed for the 6DJ8 or 6CG7 and found it worked quite well, though you should always consult your equipment manufacturer before experimenting.
I actually preferred the sound of the ECC85 to the ECC88 in almost every application except for use as a driver tube, as it appears to have less distortion than the latter. Sonically, Siemens remains true to form, providing a very transparent sound with a good amount of body and a huge sound stage. This is a very musical tube where the bass remains solid and perfectly controlled.
Final Verdict: Recommended as a high-quality, low-distortion alternative for those willing to experiment with compatible pinouts.
