In Reply to: Tube versus SS? Easy .. posted by DrM on December 13, 2001 at 23:19:29:
While tubes are more linear than transistors, tubes present many more problems when building an amplifier. Tubes require coupling capacitors and an output transformer which can be problematic at the frequency extremes. Also, since the impedance of tube circuits is high, HF rolloff can occur (it takes only 80pF at 100K to form a pole at 20KHz). Direct-coupled solid state amplifiers have none of these problems.
