| 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... | |
| Did I just cook my preamp? @obarrett When you receive the multimeter you need to read through the how to use Instruction Manual. Pay close attention to WARNINGS. MM720 INSTRUCTION MANUAL To ensure safe operation and service of the meter, follow these instructions. Fai... | |

| Did I just cook my preamp? @immatthewj Is this the meter you bought? Compact 3-In-1 CAT IV Digital Multi-Meter Is this the amp? Cary V-12; it features a dozen EL34s and each pair has a switch in between them that configures that pair to either triode or ultralinear. ... | |
| Question for Atma-sphere, will expensive power cables improve your amplifiers? @faustuss That’s it! Look at them high quality audiophile connectors. |
