| DC entering my amp? What I would do is check for DC offset at the speaker terminal outputs. Set a DMM to DC Volts and measure across the speaker cables at the amplifier binding posts with the amp on (for at least 5 minutes) and everything connected as normal, all on.... | |
| Alta Vista NP-100 schematics? There are things you can do in a pinch without a schematic. I would disconnect the output transistors on the same channel with the diode and with a multi-meter check the resistance across the pins. A shorted transistor is a common cause of burned ... | |
| Wiggle kt170 base Unless you swap the tubes in both sockets to see if the hiss stays with the tube or the socket, there is no way of telling if it is a bad tube or a bad mechanical connection. You could have a bad tube and it decided to show itself that day. Or you... | |
| The difference between an Audiophile and a Stereophile? If I built a great sounding speaker made out of plywood and roofing nails, would the audiophile buy it? | |
| Perception and Watts: Doubling of power Different frequencies consume different power so "twice as loud" would be frequency dependent in many cases. Paying for an additional 50 watts will improve low frequency performance -- you may not hear it louder but you will hear it cleaner with r... | |
| Audio-grade rectifying diode? Bypass any rectifier diode with a 0.047uF polypropylene cap and it becomes an audio grade rectifier. | |
| Help and Advice Needed: Cary Audio SLP-05 Preamp RMA Disaster With RCA inputs, does the volume fully mute? An attenuator does not necessarily mute at zero setting, it is at its maximum voltage divider impedance and a 0dBFS signal can be heard. I wouldn’t consider that to be a problem. I looked at Cary’s sp... | |
| Sharing ground wire between two dedicated circuits As long as both circuits originate from the same panel you can share the ground -- if your jurisdiction uses NEC 2014 or later. Note that 10/3 Romex has three uninsulated wires (black, white, red) and a bare ground, 4 wires total. The insulated r... | |
| Okay to use RCA adapter on a fully balanced amp? Another option is to use a Schiit EQ (Lokius or Loki Max). Plug an RCA from the preamp into the EQ input and use the EQ output XLR to go to the amp. It will convert to balanced output voltage. The EQ is probably a lot quieter that an RCA/XLR adapt... | |
| Break In Failed A few thoughts on the subject: In my experience the only thing that sounds worse new out of the box is a vacuum tube. Do driver manufacturers run new production drivers for hundreds of hours to "break in" before testing, or do they test them rig... | |
| FUSE Question...Very Confused Please Help ! You have to be careful because equipment voltage rating is different from actual wall voltage. The fuse size is determined from the transformer power rating using the equipment rating and then the wall voltage: 230V x 2.5A = 575VA Since you are ... | |
| Stored, used, crossover capacitor burn in / reforming time Cap data sheets do not spec "burn in" time to reach rated capacitance. PP caps do not dry up like electrolytics so there is no dielectric reform to worry about. Once you put the caps back in they will perform the same way they did all these years ... | |
| Ground voltage!! Order one of these and plug it into each outlet: https://www.amazon.com/Sperry-Instruments-GFI6302-Receptacle-Professional/dp/B000RUL2UU/ref=sr_1_7?crid=1BOV06ZTC7KV7&keywords=receptacle+tester&qid=1667607178&qu=eyJxc2MiOiI0LjMzIiwicX... | |
| Isolated ground in dedicated room/new construction? I would steer clear of 2-wire Romex. The hot and neutral run parallel along the flat length and this creates an RFI antenna. I use 10/3 Romex (orange sheathing) because the three wires are twisted, which helps attenuate common mode noise. I use th... | |
| At this level of high(er) end audio why not offer balanced connections? Yes, examples would be helpful so we can see where you want this discussion to go. Off the top of my head: Pass, darTZeel, Soulution, Levinson, Krell, FM Acoustics offer both balanced and XLR. D'Agostino offers only XLR, so that turns it around a ... |
