| Power cable shutting amp down I just put in a JPS Power AC+ and it seems to be overheating the amp.Overheating where? At the IEC connection? Connect the JPS pc back to the amp turn on the amp and play some dynamic music at a moderate to loud level.Occasionally put your fingers... | |
| Ground loop b/w amp and phono stage If I do not connect the ground wire to the phono stage, the sound is reduced but it is still there. Any more ideas?Ssayeed, Did you try to connect the ground to the chassis of the integrated amp? Maybe a screw on the bottom of the amp.Have you che... | |
| Ground loop b/w amp and phono stage I ended up borrowing an Aesthetix Rhea and the problem persisted. Any ideas?02-16-11: SsayeedTry another set of line input jacks on the integrated amp.Try another pair of ICs from the phono preamp to the integrated amp. Make sure the plugs are sea... | |
| Ground loop b/w amp and phono stage Ssayeed,By chance did you try lifting the signal ground from the amp's chassis with the toggle ground lift switch on the back panel?http://www.stereomojo.com/Ayon%20Triton%20Integarted%20Amp%20Review/AyonTritonIntegratedTubeAmpReview.htm | |
| Ground loop b/w amp and phono stage , if I do that, there is no sound.No buzz you mean? Complete silence? I tried an rca cable plugged into the input section of the phono stage though (Kent at Pass Labs asked me to this) and the buzz returned.An open ended patch cord connected to t... | |
| Wiring an Isolation Transformer BTW I'm still curious how it is less isolated wired as 120-120.Did you take the time and read the Bryston link I provided?They recommend running the primary in balanced mode, 120/240V (120V 0 120V), instead of single ended 120V in. As for recomme... | |
| Wiring an Isolation Transformer Also, is there a definitive asnwer out there about balanced halfing the VA rating?Let me take a stab at it again....First a power transformer is designed to operate at its rated nominal voltage and frequency. The size of wire used is directly pro... | |
| Ground loop b/w amp and phono stage But when I used the CD player, there is no buzz at all. It's only there on the input which the phono is connected to.Not a ground loop jmho.... Do you have the TT grounded to the phono preamp?What happens if you disconnect the TT from the preamp a... | |
| Wiring an Isolation Transformer 120V in 120V out will not yield all that much isolation. Better to wire the xfrm 240V in, single ended 120V out.Series the primary windings, parallel the secondary windings.One paralleled leg of the secondary must be connected to earth ground maki... | |
| Wiring an Isolation Transformer NO IT WILL NOT.Yes it will!You must treat the output rating the same as if it was configured with the two windings in series. | |
| Wiring an Isolation Transformer But some suggest this cuts the power in half, some suggest it doesn’t. Here is an example I found of balanced wiring:Wired balanced will cut the VA rating in half.....Wire the transformer 120V in 120V out.Parallel the two secondary windings togeth... | |
| Transformer--Subpanel Wiring My understanding is that if I'm needing 20 amps on a circuit, then I will need a 20 amp breaker at the subpanel, because a 15 amp breaker would trip. And a circuit protected by a 20 amp breaker would require #12AWG or larger, because 20 amps woul... | |
| Transformer--Subpanel Wiring If I understand you correctly there will be three wires running from the secondary winding to the isolated main panel. One leg will be the hot at 120V to feed the breakers. The second (center-tap?) will go to the neutral bar. The third at the othe... | |
| Transformer--Subpanel Wiring Ngjockey,Just so Iabirder understands the max a 5 KVA xfmr can be loaded is 41.67 amps @ 120V (5000 va). Technically the continuous connected load @ 120V = 80% of 41.67 amps = 33.3 amps (3996 va).Most would not use the 80% rule for calculating the... | |
| Transformer--Subpanel Wiring I've seen recommendations for a minimum 60amp breaker at the main panel to protect what is going to the sub. 1)How do I know what amperage is available to lend the sub? 2)If I can use a 60amp breaker does this mean that I can't exceed a total of 6... |
