| ELS122:
can I use a diode to amplify sound? like by driving the cathode? |
| T3sl4co1l:
Any unspecified diode type? Sure, a tunnel diode can. Tim |
| ELS122:
a 6H2P in particular. it's usually used as a detector in radios. also while we're on the topic of tube's, can I use a 6k2p tube as an audio preamp, it's meant for RF amplification and I guess it wouldn't work great in a preamp. |
| T3sl4co1l:
Wait, 6Х2П (6H2P) or 6Н2П (6N2P)? A diode is not an amplifier. At best, heater power might be varied to control plate current, but this is far too slow to be useful at audio frequencies (and if the plate voltage and current ratings are too low relative to heater power, it might not end up having any power gain at all). 6K2P ~= EF93 ~= 6BA6, is that right? I mean, it can be used, but the remote cutoff grid won't do any favors for distortion. RF tubes do tend to be microphonic, YMMV. Tim |
| ELS122:
the 6X2P (in russian) translates to 6H2P it's a double diode, and I wanted to drive the Cathode and leave the heaters alone |
