| Are film capacitors directional? Please forgive my ignorance, but once I have the meter, what exactly do I do?There's no ignorance to be forgiven, aside perhaps from my own :-)Thinking about it a little further, I believe that to get meaningful readings with a battery powered DMM... | |
| Are film capacitors directional? Also, Bryon, if you use a battery powered DMM instead of an AC powered oscilloscope, it may be that instead of using your hand as the "signal source" you might have to drape an AC power cord (that is conducting current) over the capacitor. The 50 ... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Ralph, the present (original) value is 100 ohms. Do you still feel that is not the problem?Best regards,-- Al | |
| Are film capacitors directional? Good info, Rodman.Bryon, if you have a good digital multimeter, which can read AC voltage down into the millivolt region, you could probably use that instead of an oscilloscope. Note in the jimmyauw writeup that the amplitude scale on the scope di... | |
| Coax to Optical Converters Anygood? If in fact the unit's DAC function is insensitive to jitter on the incoming signal, then it should also have minimal, if any, sensitivity to the quality of the converter (assuming the converter is at least good enough to function reliably).On the ... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade No, don't solder a resistor between the RCA and pin 1 of the tube socket. That would put the 1K in parallel with the 100 ohms, resulting in an overall resistance of about 91 ohms.Hopefully you can unsolder the wire that is presently connected to t... | |
| Which Cables Are of Most Importance? Hi Frogman,The question is reminiscent of the age-old debate about "speakers first" vs. "source first." As many past threads have made clear, a reconciliation between the two opposing positions seems unachievable. FWIW, I happen to be in the camp ... | |
| Shielding components from EMI/RFI... Help please Hi Bryon,Presumably the shielded cable is reducing the amount of rfi/emi that escapes from the cable and couples onto circuit points elsewhere in the system, most likely points that are "after" the reclocker circuitry. There are probably a number ... | |
| What did you own in the 60's? A tube AM/FM clock radio (which worked very well); a couple of transistor radios; and during the last few years of the decade a $20 portable record player.Regards,-- Al | |
| Shielding components from EMI/RFI... Help please Hi Bryon,Yes, you're right. After looking at the photos I believe that the two small blue objects just above the green wire are capacitors that are provided for purposes of filtering high frequency noise that may be present on the incoming AC. One... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade I agree completely. 100 ohms sounds way too low. And as the link you provided indicates, too low a value for the grid stopper resistor of the input stage could very conceivably result in rfi problems.According to some quick calculations, 1K strike... | |
| Shielding components from EMI/RFI... Help please Hi Bryon,My suspicion would be that the connection from the power supply is connecting the ground on the DC output side of the supply to chassis, thereby connecting the G68's circuit ground to chassis. That is often done, although as you surmise i... | |
| What's up with all those clocks If the input signal into the Trinnov has high jitter (say I use a poor USB converter), the DSP processes this poor quality signal. To what extent would this impact the end SQ result if most jitter is eliminated downstream, just before the DAC?Jitt... | |
| What's up with all those clocks The literature on the PWD MkII indicates that its NativeX Digital Lens function "Will reduce incoming jitter levels to below 1 pico second, regardless of how jittered the incoming signals are .... NativeX works on lowering jitter on any selected i... | |
| Thoughts on Neutralaudio X-Drei, wrt BSG QOL The lack of detailed technical information on what these devices are doing makes saying anything about them very speculative, at least without hearing them (preferably on multiple systems). But fwiw:02-15-12: SpiritofmusicSince they work on differ... |
