Wood armwand vs Metal armwand I also do not find the sound to vary from day to day, with my Reed tonearms. When rechecking my settings they are not different either. So at least IME stability is a non issue.How about year to year? You may not notice a very minor change from on... | |
good preamp for dynaco mk3 monoblocks with maggies Zvovchik, since you are thinking of getting vinyl, you really owe it to yourself to get a tube preamp.If you run an outboard phono section you have two problems- one is the audible effect of the additional connections (interconnect cable and the l... | |
triode versus pentode When you have a setup that allows you to switch between triode and pentode, you should understand that the amplifier is likely optimized for pentode rather than triode.Triodes have a lower output impedance and so will need a lower turns ratio on t... | |
Contact info of Steve Huntley Johnhaines, if you need the amp repaired that is no worries. We do lots of tube equipment. | |
Quad 63 ESL Rebuild - A Horror Story Take copious photos so you can show that the panels have not been serviced. | |
Wood armwand vs Metal armwand ^^ this. | |
Wood armwand vs Metal armwand The trick here is you want to control resonance in the arm wand, such that it does not talk back or editorialize.Most wood arm wands I have seen do not appear to be treated for resonance issues. Some might argue that they don't need that; they wou... | |
What is the acceptable range for tube bias? FWIW if the manual says '0.4V' then we are talking volts not milliamps. So the volts setting is correct. I usually set the bias slightly low if the amp has just been started up. Then I check it after a few minutes to verify that its OK, finally af... | |
What is a good power amplifier? Unless its really overbuilt, if you want it to sound nice you will be better off getting separate amplifiers rather than all in one box. You say the speakers are efficient and you are "wanting something that won't make my tweeters explode my ear d... | |
tube cage solution: appj PA0901A N3 miniwatt Cats know about something called 'hot'. You've no worries about the cat burning itself. | |
Another Platter Speed queston If there is build-up on the motor spindle due to perished belt material, it can run too fast. | |
empire 980 arm mistracks with various cartridges If adjusting arm height has no effect on the bass the arm is having a severe problem!The bearings don't go out of adjustment, unless someone messes with them. They fail. Over-tightening the bearings is a simple way to damage them. They are suppose... | |
empire 980 arm mistracks with various cartridges Have you adjusted the arm height? That can play a significant role in the bass playback.Also, the plinths on the original Empires are pretty well a joke. They resonate quite a lot. Also, the bearings in the 980 are quite fragile and they may not b... | |
transformers/output impedance I think the point that Ralph was trying to make is that using a meter to measure an amp's impedance/resistance at the output taps is **not** what the term "output impedance" is speaking to. Instead, it's referring to the amp's operational behavior... | |
transformers/output impedance Hi Bifwynne, first you are correct that the cathode cross-coupling thing you see in ARC amplifiers is a form of negative feedback. I've used this a lot when modifying Dyna ST-70s. I think the oldest amp I have seen with that was employed in a Lesl... |
