| How deadly is transformer hummm... @jea48 This two-story single family dwelling was constructed in 1986. I have not checked the mains voltage. I imagine this requires a volt meter, which I do not possess. I see a number of them for sale at the Home Depot, which is the closest such ... | |
| How deadly is transformer hummm... Tubes have been removed and the hum persists. Second email out to Had. | |
| How deadly is transformer hummm... Mr. Had has already responded, making an impression and stands firmly by his product. He's given me a test of sorts, to remove all of the tubes in the amp, to then see whether the amp hums. This I will address in the morning... more thereafter... ... | |
| How deadly is transformer hummm... ...and now I have email out to Dennis Had... | |
| How deadly is transformer hummm... I've got an email out to the seller of the amp, to see if he can reach out to Mr. Had, for some advice. The amp was made in April and there shouldn't be any transformer degradation of significance by this time. I would open it up with a little cle... | |
| How deadly is transformer hummm... @jea48 the amp is entirely quiet at the speaker drivers; the amp was probably humming within the chassis from the start, but I did not hear it until a few days in.I bought the rubber washers, but further comments seem to indicate that tightening o... | |
| How deadly is transformer hummm... @mrdecibel So, if I open the amp and I'm tightening things, inserting bushings, etc., I will have the amp unplugged, and I'm wondering what I need to do to protect myself from errant charges that might stop my heart... My sense is you are pointing... | |
| How deadly is transformer hummm... @mrdecibel this is done inside the amp, covering the entire transformer, from inside the chassis, with dynamat? | |
| How deadly is transformer hummm... @atmasphere how tight? I see the four screws from the top, so they are accessible from above the amp. Why remove the bottom panel? | |
| How deadly is transformer hummm... @bdgregory the hum is not audible from the speaker drivers. This is a mechanical event, coming from within the chassis. @brownsfan how do I detect tube issues like you describe- microphonics, etc?@stereo5 I always enjoy the humming of my wife, but... | |
| How deadly is transformer hummm... By the way, the title of the original post should have included a question mark, and slightly more qualified phrasing:"How deadly is transformer hummm, to the amp itself...[?]" | |
| Speaker load on tube amplifier... @atmasphere Super helpful, thank you. I have read your comments on speaker ohm rating many times. I comprehend your perspective, and I find it interesting that the engineer of my speakers praises the 4ohm load, for other reasons. It seems what is ... | |
| Tekton Double Impacts I've got a Dennis Had fire bottle on its way in, to arrive late in the week. I hear great things about them, from just about everyone. I won't be rockin' hard with it at about 10wpc, but no matter, my preferences are acoustic and jazz, and about 7... | |
| Tekton Double Impacts I would like to hear more about tube amplification with the double impacts. I have the Moab’s. I’m running them off the Schiit Aegir and it supports the speakers marvelously. I keep hearing that tubes are the way to go for clarity, soundstage, or ... | |
| From one experiment to the next... And a question... how will an amp like the Zen Torii control the bass, which amounts to two 12" woofers in each Moab? |
