| TRL Dude or Joule 150 MKII for Major Pre Upgrade Thanks Al. I will check into the cable capacitance to be sure I am doing all I can for best sound. | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Update. The use of a Jensen input transformer under the brand Iso Max completely removed the buzz to a dead silence. Simply place the input transformer between the amp and preamp. Single ended preamp into the Jensen Iso Max using my RCA ic's and o... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Jognsonwu, thanks for your insight. I am not sure how to wire such a resistor as my amp has a circuit board for each input tube/channel. Hard, if not impossible , for me to wire in a 1k resistor. Wish the amp was point to point wired! It may be po... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Correction the grid stop resistor should measure over 1000 ohms and often is a very high value. | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Ok, did one additional measurement per the instruction Jognsonwu above.I measured the ohms reading from the RCA center to each of the eight 6sn7 socket pin numbers.I did this to check the input grid stop resistor.This grid dropper resistor is used... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Atmasphere,What about the fact that a Passive Lightspeed pre, cd players and a Bel Canto pre with average to low output impedances caused the same buzz with this amp? Does this rule out the high preamp output impedance theory into the Atlas? | |
| Is there any truth to this question? Regardless of the speaker's sensitivity I have found not driving your amp too hard and having more power and headroom available is a very good thing. In my current rig a highly touted 70 watt tube amp was displaced by a Hybrid amp with 4 times the... | |
| Does listening fatigue go away??? I have been at this audio thing for 35 years and don't think it is the digital thing. It is system synergy and your unique set of ears. No, it won't just go away if you change nothing. Sorry.....I use a digital front end and no trace of fatigue wi... | |
| Dont laugh I am crying! | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Vett93 summed it up very well. My speaker and other cables really did not change position. My speaker cables are simply solid core copper runs and very straight forward. Changing power or ic cable brands did nothing to change the hum. | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade I found a bunch of unused RCA cables and connected the ground and center wires to short the jacks. I places these on my 3 sets of unused preamp inputs. Still have the buzz. Still think this may be a good idea however. | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Thanks Al. I just inserted two shorted RCA jacks on the unused crossover inputs on the amp. Still have the buzz however.Wonder if my extra preamp inputs should be shorted? | |
| Possible impedance matching issue with subwoofer? Wanted to update folks on my progress. Well I have two subs now hooked up to my system. I have a/b'd the sound with and without the subs. When I turn the subs off I also remove the ic's from my preamp to compare the sound.No loss of highs. No loss... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade I just read this in my Aesthetix Atlas's manual. " each channel is a balanced bridge amplifier, thus the negative speaker terminal is not a ground, and cannot be connected to a system ground or loudspeaker system with a common ground. Consult your... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Correct, passive speaker. I ha!ve been working with Vett93 and he has stepped me through all kinds of tests. Thank you for being so patient with me! Through it all I still have the same buzz out of both speakers. The buzz is not present under thre... |
