The 6H30 is a frame grid triode, and like all frame grid triodes (such as 6DJ8s) is prone to oscillation at some very high frequencies unless care is taken in the design. This opens them up to microphonics associated with the parasitics. Its a nice linear tube good for instrumentation but really isn't suited all that well for audio.
