| Going Price for Apogee Divas? That’s blue book trade in, not sale price. A dealer will pay 4200 for those speakers on a trade in and then put them on the floor for at least 30% higher, or $5500. Sellers usually research before they state a price. | |
| Seeking power conditioner recommendations / hum elimination If LED lights are buzzing that could mean those lights are on a dimmer made for incandescent bulbs. Those triac dimmers can put electromagnetic interference on your circuits causing both the audio ground loops and the lights buzzing. If they are n... | |
| Using 15 amp power conditioner and power cords with 20 amp wired outlet. If you install a 20-amp breaker, run a #12 or #10 branch circuit and install a Nema 5-20R receptacle, that will cover all 120 volt options for 15 or 20 amps.My advice: use romex 10/3. Cut the bare ground and use the insulated red for ground connec... | |
| Primaluna evo 400 - unmatched tubes It doesn't matter if the tubes are matched in the Prima Luna. The adaptive bias circuit sets the idle bias current of the output tubes by sensing a voltage drop across a resistor. That voltage modulates a transistor to either increase or decrease ... | |
| Educate me about gain and amp/preamp matching Look at it this way: assume two cars with the same engine are accelerated to 50 mph. The first car requires the gas pedal depressed 1-inch and the second car requires the pedal depressed 1.5-inch. Both have a different gain but both have the same ... | |
| Lumin or Aurender I have the Aurender N100H. The thing that most impresses me is that Aurender tech support can log into your player and correct software related issues. That is one reason, and a big reason, I am hesitant to seek out upgrades outside the Aurender p... | |
| Ever feel like a "low dollar" customer that your dealer doesn't think worth their time? When you tell a store you are an interested buyer IF they carry something you like, you are not seen as a low dollar customer. You are seen as a waste of time. A dealer has a product line. If you are interested in one of those products -- and make... | |
| Do Ethernet cable Cat8 DH Labs need burn in I 've had that cable now for 6 months and can honestly say that I have not heard any changes over that time. But it did make an improvement right out of the box compared to the Amazon cable it replaced. | |
| Question for amp experts Bang & Olufsen Beolab 50 and 90? | |
| Preamp and impedance question @gte357s No, what I meant was that if you have both 8-ohms and 4-ohms on the secondary, using 4-ohms will not be a problem as long as you don’t expect the maximum power the amp is capable of. The secondary will draw more current and if the xfmr an... | |
| Preamp and impedance question You can put a volume pot on the amplifier, the only reason most amps do not have one is it limits their market to customers with only one source. What you have to take into consideration is what input impedance your source wants to see. Anything a... | |
| What could cause this amp to fail? A clicking sound to me is a relay not latching. It’s possible that an overload or dc offset protection circuit has a bad holding/charging capacitor that feeds a transistor holding a speaker protection relay closed. | |
| Fuse location ....( if any) in MGA Mitsubishi DA P600 Pre-amp A lot of these old units have the power switch on a circuit board connected by a plunger to a push button on the front panel. Follow the plunger to the circuit board. The fuse should be on the board right next to the switch. | |
| Missing caps on EAT E glo Petit phono preamp Without the schematic as a reference you cannot tell if the cap is missing. It could be intentionally not installed. It is not uncommon for mfr's to put spaces on pcb's for future components anticipating design changes or upgrades -- or they could... | |
| Are integrated amps technically better than separates? ... and over the top power supplies wreak havoc on low level preamp signals and negate any benefit from "direct" connections’. One reason why most top-end preamps have separate power supplies. |
