| Did I just cook my preamp? The deductible is too high, the v2 of the 110LP new is only $600 and renter’s insurance would give only the actual/market value of the used one I have, which is considerably less than $600. it’s not really a problem, I’m just grateful to be alive... | |
| Did I just cook my preamp? Yes I’m going to replace them with power strips and I’ve obviously stopped plugging anything with three prongs in there. As for the landlord, he’s sent someone to fix it, but he seems unwilling to replace the preamp. He doesn’t really seem to unde... | |
| Did I just cook my preamp? I suggest you try another test. Plug an OEM power cord into outlet 1. Insert one of the test lead probes into the IEC female ground contact. Turn mm to V and touch the other test lead probe to a bared (unpainted) metal place on the heat radiato... | |
| Did I just cook my preamp? Hey Jim, the reason why I didn’t have an issue before is that I wasn’t using outlet 2 before. Everything that needed a ground was in outlet 1. Only after I moved things around could I access outlet 2. thanks again to you. Thanks also to you Devin... | |
| Did I just cook my preamp? I made the following measurements, both on V and LoZ. All the measurements were identical on both settings. I made the measurements two times: once with the 2-to-6 outlet converters on, and once with them off (accessing the bare outlets). The 2-to... | |
| Did I just cook my preamp? I haven’t yet had the chance to do the tests you suggested in your last post @jea48 I just want to mention that @jea48 ’s advice, contrary to the statements of @erik_squires and @devinplombier , has been essential to understanding what’s going o... | |
| Did I just cook my preamp? Do you still measure 120V between your two grounds when your DMM is set to standard AC voltage mode? Yes I measure 120Vac across the grounds of the two outlets in V AC mode on the MM. well, to be clear, both outlets have 2-to-6 outlet converter... | |
| Did I just cook my preamp? There is continuity from the ground prong of the TT to the tone arm ground lug. No continuity from either of the other two prongs of the TT. I attached one three prong power cord to the outlet where the amp/preamp/CDP are connected and then the o... | |
| Did I just cook my preamp? Wow, listen to this. i unplug the preamp from power. I unplug all interconnects from preamp. I leave the grounding wire connected, which grounds the preamp to the record player tone arm. I put one lead of the multimeter in the ECG coming from the... | |
| Did I just cook my preamp? I just plugged everything into all the outlets as it was last weekend (minus the interconnects between phono and amp) and re-did the test where one lead is on preamp output, one on amp analog 1 input rca plug. 121Vac on V 68.9Vac on LoZ 0Vdc... | |
| Did I just cook my preamp? I haven’t mentioned it yet. You may have damaged the analog L & R input circuitry in the RR2160 amp. The pair of RCA jacks you plugged the ICs into from the phono preamp. This wouldn’t be a big deal if the three other RCA inputs still worke... | |
| Did I just cook my preamp? 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 RR2160 amp. Should of done that to begin with... Both units powered on. 5.5Vac on V 0.02Vac on... | |
| Did I just cook my preamp? Ok I did AC again and verified the previous numbers. SMPS (one lead in ground of OEM ITC, the other on the sleeve contact of the SMPS): 48.7 V AC on V 0.125 V AC on LoZ | |
| Did I just cook my preamp? I tested the outlets where things were plugged in. The hot/neutral is reversed. So the hot is the longer left slot, the neutral is the shorter slot on the right. The ground appears to be functioning. | |
| Did I just cook my preamp? Does the 120Vac IEC inlet connector on the back of the sub have three prongs? Therein an equipment ground prong? My bet is yes. Correct? Yes I verified your question about subwoofer in earlier comment today. The subwoofer pins are only two even... |
