| Isolating Digital Noise, need help. UPDATE...I spoke to the owner/tech of the only authorized Sunfire service center regarding the grounding design of their amps. He said in a Sunfire amplifier that the chassis, power and signal ground are connected together.But yours is not. Throug... | |
| Can stabilant 22 be used for power cords and vacuum tubes? That’s why Deoxit for example is safe to use on tube pins. That’s also why commercial aircraft use it on communications electronics. How much heat are you talking about? What's the voltage? Here is the typical statement found in an ARC owners man... | |
| Can stabilant 22 be used for power cords and vacuum tubes? DO NOT use any type of contact treatment on power tube pins or tube sockets! | |
| Quicken the burn in time for new speakers by using a cheaper SS amp? I wouldn’t want to leave a tube power amp left unattended for hours on end. I also can’t see the clock running wasting tube life of the power tubes. Average life of power tubes being around 1500 to 2000 hours.The solid state amp sounds like the wa... | |

| Isolating Digital Noise, need help. And I just thought of something. I bought my amp used from a HiFi dealer; it was his personal amp. Could he have lifted the ground for use in his system?Another reason to pull the top cover off the amp for a look inside. **NOTE: Naturally unplug t... | |
| Isolating Digital Noise, need help. jea, since you commented on the high gain of the CDP (2.7V), I checked it by playing thru a different preamp input and the gain is too high. Ralph put in the -6dB pad for me as a mod due to the CDP’s high gain spec. And it sounds very good. Al, (a... | |
| Isolating Digital Noise, need help. Jim (Jea48), you provided an excerpt and a link to Mr. Hansen's statement in the last post on this page. However, I would not interpret his statement to mean that signal ground should be connected **directly** to the chassis, as that can be condu... | |
