| Leaving tube amps on. @pindac , well, the amp had been in service for many years and caps do occasionally fail, and I think that this failure was due to a mistake I made when I was doing something with the amp. But, my point was: that if the amp was fully powered on ... | |
| Leaving tube amps on. @tattooedtrackman , on bias and red plating, a few years ago (I think it may have been some time in '20, I had a coupling cap fail on one side of my Cary V12.. I won't try to explain the science or theory of whatever happened within the circuit... | |
| Solar flares are here, everyone unplug your dryer! Most notice that I do use proper capitalization... You could have fooled me. unless I’m making a Point or Drawing (hopefully) Attention to Unless you are making a point of, and drawing attention to, words at random. *Erp* . . . *f* . . . B... | |
| Living With A Class A Tube Amp You most likely have either ultralinear or pentode pentode being a purer circuit without all the feedback as in a Ultralinear circuit. I always thought that ultralinear was synonymous with pentode, and that triode was the purer circuit. Was I ... | |
| Solar flares are here, everyone unplug your dryer! @hickamore , Tucker Carlson's boyfriend told him the dryer was part of the election theft scam. | |
| A stupid question(s) about power cords Thanks @mrdecibel ; I will keep you posted. I had to unplug everything to facilitate other goings on in the room, but I am hoping to have everything hooked back up by tomorrow. Life if full of compromises. I do believe that an improvement could b... | |
| Leaving tube amps on. This isn’t exactly applicable to your question, and what I do might not fit into the structure of your life, but I generally know, on any given day, when I will be listening, and it usually after I eat dinner. So a couple or three hours before I a... | |
| Living With A Class A Tube Amp no need to bias tubes. Don’t you still have to adjust the bias on the one output tube per side that you do have? That is, unless it is self biasing? | |
| Living With A Class A Tube Amp @immatthewj FWIW, 'pure class A' is a marketing phrase. As far as engineering goes, a circuit is either class A or its not. None of this 'enriched class A' stuff you often see (such amps are class AB). In your case my guess is class A1. I thoug... | |
| Living With A Class A Tube Amp @atmasphere , thank you for the explanation--that is interesting and makes me a better informed hobbyist. "Pure Class A" was a direct quote from the owner's manual, so that is all I know about it, as my ability to comprehend electrical theory ... | |
| Surge protector Has anything changed, with your AC mains power that feeds your equipment? Any more thunderstorms, since you started reading Audiogon Forum posts? No... What’s that tell you? @jea48 , that I am becoming neurotic and needlessly paranoid in my o... | |
| Living With A Class A Tube Amp @atmasphere , quoting from my owner's manual: "CIRCUIT TYPE: Push-Pull Ultralinear Amplification in Pure Class A" then "POWER OUTPUT 50 watts-Triode 100 watts - ultralinear." As always, I defer to your knowledge on these subjects. I had ju... | |
| Living With A Class A Tube Amp This is not a class A amp. It is a push pull. @carlsbad2 Push pull amps can be class A no worries. The Dynaco SCA35 using a pair of EL84s was a class A PP integrated amp. We’ve been making class A triode PP OTLs for decades. If you were not a... | |
| Surge protector As far as power going out and coming right back on, or going out and staying out 5 or 10 minutes or an hour, that happens here in western Pa. all the time, and often there is no apparent reason, such as a T’storm, for it. In the past I did not unp... | |
| Solar flares are here, everyone unplug your dryer! ..You have proved it with your behaviour against asvjerry... Do you remember ? How could I forget. Yes you remember because after mocking his innocuous post now you cited him as a rational reason justifying your behaviour against him ... W... |
