| Hypex N core module Naturally your not going to tell us how it’s done, I’m hope for you that you can do it, but also sceptical at the same time, as minds more attuned to solid state Class-D topology than yours have not succeeded, save for Technics who are half the... | |
| Earliest "MOST WANTED" gear My first really serious system, about 1975, was a Harmon Kardon Citation 2 power amplifier, with a Citation 1 preamp, rack mounted in a nineteen inch military rack 7 feet high, which also contained my Technics SL-1100 turntable, which was on a dra... | |
| Audio Research Reference 5SE modifications/bypassing output caps I do take exception to Atmasphere's comments about using a bypass cap across power supply filter caps. My experience with bypass caps in a PS is exactly the same as with coupling caps. I can always hear the effect of the bypass cap and it cau... | |
| Audio Research Reference 5SE modifications/bypassing output caps Bypassing power supply caps is a good thing. Bypassing audio coupling caps results in smearing- the more resolution you have- the more you can hear it. The caps have different ESRs, different dielectric coefficients; its easy to see why this is so... | |
| Hypex N core module We've already been listening to the amp. FWIW the squarewave response you linked does look pretty bad. Our tube amps can do better than that!Obviously we're not letting this thing out without it doing what its supposed to do. The thing is, you can... | |
| Hypex N core module I completely agree that switching frequencies have to be increased!But, the problem is not switching speed! The problem is how long it takes for the device to turn on and off, which is different. Because that takes some time, the circuit has to wa... | |
| Hypex N core module "if you want to have your product performing at the cutting edge it is not possible with today’s known switching technologies. In order to come close to the performance of the best linear design we would need high-current semiconductors that ... | |
| Hypex N core module @merrillaudio +1In the future when technology allows the switching can then be much higher to allow the output filter to do it's job properly and cut out all the switching frequency noise without effecting the audio band.This statement is false.... | |
| Hum!! If the amp can be cycled off and on with the hum going away for a while, its not a bad solderjoint.Tubes can do this if they have a cathode/filament short. But the problem is in both channels so I don't think its that.A filter capacitor in the pow... | |

| Speaker Sensitivity AND Power Requirements Generally speaking, In that room 22 watts usually would not be enough with speakers at this level of inefficiency. The thing is, this speaker does not handle a lot of power and in that regard your receiver is a perfect match. So if you plan to be ... | |
| Repairing Sansui G6000 FM and bulbs It is very common for the switches on receivers like this to have some corrosion. This could easily be why the FM isn't working. They do not need to be replaced! You can clean them using Deoxit (with the green highlights on the spray can) in a spr... | |
| Using tube amp with electrostatic speakers. What occurs to the sound of the speaker when the transformer saturates or begins to saturate? Is transformer saturation a voltage or current issue?Distortion- Its pretty obvious. Its a power issue- both current and voltage (of which neither can... | |

| Using tube amp with electrostatic speakers. @lewm Yes, the tricky bit is that the transformer impedance increases as frequency goes down. So with a given capacitance with increasing impedance, the crossover point moves lower- there is no set crossover point! This is why the resistor is ther... |
