| Question for Atma-sphere, will expensive power cables improve your amplifiers? @faustuss | |
| Did I just cook my preamp? @obarrett said: his wouldn’t be a big deal if the three other RCA inputs still worked. Last weekend I connected the preamp to analog input 4 on the amp and it made the same soft bump sound. I just remembered the blue sound node also has an integ... | |
| Did I just cook my preamp? @obarrett Said Note... Inside heavy light gray line is me. Outside heavy light gray line is you. Saturday, check for voltage from the outer shell of the output RCA jack of the phono preamp to the outer shell of the analog input RCA jack on the... | |
| Did I just cook my preamp? @obarrett Said: I will answer this first. I’m obviously leery of connecting them again but if there’s some way to do so safely I might be willing to try. Thanks for all your help. NO, I wouldn't if it was my equipment. I haven't mentioned it... | |
| Question for Atma-sphere, will expensive power cables improve your amplifiers? @faustuss The Audiogon forum program is a little antiquated to say say the least. If you want to post a quote you need to use the two quote thingies in the header of the message box. They are similar to these. Quotation marks . Click on quotat... | |
| Question for Atma-sphere, will expensive power cables improve your amplifiers? Please! It's just a freakin' wire! Mojo Digital Power Cord What was wrong with the OEM power cord that came with the equipment you installed the audiophile power cord on? https://www.audiogon.com/systems/11950 . | |
| Did I just cook my preamp? @mark200mph I could be wrong, ( the amp hasn’t been checked out yet) but I think the phono preamp is the problem. I base that on this resent post from the OP. 03-28-2025 at 08:52pm But since all this I’ve listened to about 3 hours of music u... | |
| Did I just cook my preamp? @obarrett I don’t remember reading a post where you responded to this. If you did not read, measure, high voltage, or any voltage... Question... Is the SMPS 120Vac plug in blades the same width or is one wider than the other? Therein polarized... | |
| Did I just cook my preamp? @obarrett Said: Yes I verified your question about subwoofer in earlier comment today. The subwoofer pins are only two even though the power cord has three prongs. So I assume it’s ungrounded. But note the CDP is grounded and the amp is sitting ... | |
| Did I just cook my preamp? @obarrett Said: I think I messed up on the DC measurements, i think they were AC. so let me try again: SMPS (one lead in ground of OEM ITC, the other on the sleeve contact of the SMPS): 0.6 mV DC on V 0.0 mV DC on LoZ SMPS (red lead center, b... | |
| Did I just cook my preamp? SMPS (one lead in ground of OEM ITC, the other on the sleeve contact of the SMPS): 48V on V 0.13V on LoZ thoughts? 48V AC on V Might not be real power. 0.13V on LoZ real power .... ??? Thinking on this one. . SMPS (red lead center, blac... | |
| Did I just cook my preamp? i then unplugged the phono, connected it to TT via RCA Input on phono, plugged in again. Measured 49V with red lead on the shield of the interconnect plugged into the R input of the phono, which dropped to 0.14V on LoZ I would NOT connect the i... | |
| Did I just cook my preamp? The CDP appears to be grounded with three pins and the power cord has three prongs. The amp is placed on top of the cdp so they are touching. OK ... @obarrett Hopefully you can understand my long above post. Looks like I should have proof re... | |
| Did I just cook my preamp? EDIT: Be careful, the outer sleeve contact of the SMPS power cord connector may be Hot voltage ground. Should read: Be careful, the outer sleeve contact of the SMPS power cord connector may be a Hot voltage to ground. EDIT: Next, depending on... | |
| Did I just cook my preamp? @obarrett Curiosity killed the cat. Assuming the subwoofer uses the EGC, (Equipment Grounding Conductor) from the 120V wall outlet, and assuming the sub amplifier’s circuit ground is connected to the chassis, (high probability), and therefore... |
