| Electrician's advice wanted: safely lifting ground sorry, Jea48. I am not familiar with the specifics of the transformer. But I believe the answer to your question is yes. One amp had signal ground connected to the chassis and one did not. Coincidentally, I believe that it was work on a pair of ne... | |
| Electrician's advice wanted: safely lifting ground Yes, both sets of jacks are isolated from the chassis. However, one amp had it's inputs tied to chassis ground so in effect one set of inputs was connected to chassis and one was not. Either amp, used by itself, is completely quiet. Yes, it is two... | |
| Electrician's advice wanted: safely lifting ground Did I confuse things by not stating that there are no cheater plugs in use? :-) I do have a habit of glossing over fine details. | |
| Electrician's advice wanted: safely lifting ground I'll try to explain, which means I just may botch this up. :-)The hum was only between the two amps. Everything upstream unplugged. Only the amps were on. Ground loop between the two amps. The cheater plugs proved this.Now, amp A had a ground conn... | |
| Cart not parallel after Mint LP alignment? Please take Raul's advice if all you are going to do is come back and tell the vast majority of us we must be daft, or can't hear, or have no experience, etc, etc! | |
| Electrician's advice wanted: safely lifting ground Tbg, IT is not the chassis ground! Chassis ground is intact, still there, grounding away, at the AC input. The inputs to both amps are grounded back to the preamp. The lift is to the input connections ONLY, and they are tied to the power supply gr... | |
| Cart not parallel after Mint LP alignment? Why the MintLP seems to us better when it is not?, IMHO because when we use it what we do we do with more accuracy,I don't think that anyone who uses a Mint LP protractor has every claimed it to do anything more than this. This is pretty much what... | |
| Electrician's advice wanted: safely lifting ground is why are you using equipment that is so poorly designed that you have to lift the ground to avoid hum?Thanks for your opinion, but did you read my last two posts? The only ground lifted is the chassis ground to the INPUT connectors. The chassis ... | |
| Electrician's advice wanted: safely lifting ground Folks. I did contact the person who built/mod'd my amps and it was he who provided the solution based on my experiments to track it down. Once I opened both amps, the problem was clear. One amp was using wbt input connectors and had a connection b... | |
| Electrician's advice wanted: safely lifting ground It is not safe. Thanks anyway, I got the answer and a better solution. :-) There is a ground wire that runs between the grd at the input connectors and over to a chassis ground near the ac inlet. I removed that connection and things are every bit ... | |
| Fozgometer? My position is that setting az by some measurement technique is a good way to get to the ballpark. It is still required to fine tune by ear to get the best sound, IMO. Saying that, I realize that most people will just stay with what the meter tell... | |
| Fozgometer? Nice tip, Restock. I'll give it go on a PC with TrueRTA. Thanks! | |
| Cart not parallel after Mint LP alignment? OOOOOO! You just lost your accolades, VP. Back to school for you. ;-) I won't waste any of my time with ye. Bye. | |
| Fozgometer? No, I believe it would make a difference in that with pink noise, and white noise, it would be even more necessary to have a 1kHz notch filter as these distribute power over the spectrum. I would guess that even with a 1kHz test tone on an LP you ... | |
| Cart not parallel after Mint LP alignment? Bob, with the Mint LP, it isn't so much a question of which alignment geometry is better, Baerwald, Stevenson, Lofgren. It is the fact that the Mint facilitates a more precise cartridge alignment. |
