| Tube problems 6922 Additional thought is "gassy" tubes, although I can't guarantee that would cause regular variations. While monitoring the filaments in reduced ambient light, also note if there is any visible ionization in the bad tubes compared to the good, just ... | |
| Tube problems 6922 I might guess a thermal effect - perhaps either:Control grid position or geometry changes, thus altering plate current, orConnection problem with the filament, causing it to separate when hot but reconnect quickly as it cools, thus varying emissio... | |

| What ever happened to Direct-to-Discs? Audiophiles began buying CDs, despite Doug Sax's "Stop Digital Madness" campaign. | |
| Anyone heard of George Walsh Try http://rcs.law.emory.edu/rcs/artists/w/wals5000.htm and see if that is a possibility. | |
| Anyone heard of George Walsh Life's been good for Walsh, Joe. | |
| Applause: Bummer Applause on Jazz at the Pawnshop can sound very realistic and the music sounds fine, too. How about, indeed, having one or more legal friends stand in front of your system and applaud to see what the room does with it, just for kicks? | |
| Title of Dave Matthews song??? Apparently it's not Dave Matthews - it's The Watchmen. Album is "Silent Radar". Song is "Stereo" Released 1998 - HDCD.Found it with and AltaVista search on "my life is a stereo". | |
| BIAMPING Time for fairness. A question on another thread about stability/load rating when bridging made me realize the point of Sean's perspective on "effective" load impedance. While the two amps being in series with the same physical load does account fo... | |
| Deleterious effects of bridging ?? Bridging does not result in seeing half the speaker impedance. There is no complete circuit to just the + or - terminal. Bridging puts the outputs of the two amps in series, effectively doubling the available output voltage swing. The same gain se... | |
| Bridging Amps for Subwoofers Make that "halve". Thank you. :) | |
| Bridging Amps for Subwoofers Bridging does not half the current. Read a recent thread entitled BIAMPING under Speakers. | |
| BIAMPING Sean's answer is excellent overall, but the fact that you double the voltage applied to the speaker and therefore double the current (if the amp has the ability) through the SAME load accounts for the 2*2 times power. (*2 mean to the power 2, or s... | |
| BIAMPING More answer - in the example, if you can't play your system loud enough (at least on peaks) then perhaps you are output voltage limited and need the higher voltage swing to drive your speakers (and ears) to their potential. Voltage limitation like... | |
| BIAMPING Half an answer - Using your 125W example, assume a 5 ohm nominal speaker impedance for convenience. If the amp can supply the 125W to the 5 ohm load, it is supplying 5 amps. P=I*2 x R > 125 = I*2 x 5 > 25 = I*2 > I=5. To do this, the outp... |
