Is it normal that if I tap on the pre chassis that I can here it slightly in the speakers (like a record player picks up taps and such) just curious Chad
Hell, I wouldn't even wink! SS sucks the music right out of the grooves and craps all over it! Hey, Nrchy, did you ever figure out how to bias that tube amp you bought? :-)
You've got a great hybrid preamp. I like the suggestions above. Go with something new and reliable to start, then roll into some NOS later. With only one valve, you can afford top notch NOS.
This was noticed after I rolled the stock Sylvania, with a NOS phillips tube, I dont know if it was doing it before, its not like I walk around tapping equipment (I like to tap my feet though), anyway maybe I need to re-install first tube, as of now I have no tube damper....thanks guys
YOu may not even have a microphonic tube. If you tap a tube directly, you will most likely hear a slight noise from your speakers. When tapping your chassis, depending on the tubes' isolation, you are most likely just transferring the tap to the tube. I'd be alot more worried if I were hearing noises WITHOUT things being tapped!
