| Red Plating?? That is 5VA, not 5A. This is a low voltage transformer for things like doorbells.https://www.ebay.com/itm/Edwards-590-Transformer-10V-5A-Load-120V-Line/121034476341?hash=item1c2e378...Ebay has premade bucking transformers: https://www.ebay.ca/itm... | |
| Truly Balanced Cheaper Preamplifiers? When AR were questioned as to how the amplifier can be fully balanced, they said: The REF Phono 3SE does not have balanced inputs. We create a balanced signal after the inputs using a phase inverter. What turntable are you using that has balanc... | |
| Red Plating?? This all sounds scary to me the kt88 tube runs at a much higher voltage than the 6550 and the bias current is different also. The two are not that different. In looking at the TungSol plate current, its rated at 140mA (max) where the KT88 is rated... | |
| Class D Please don't be stupid. It is stupid to respond to George.....he is a rock....he will never move from his position.....and he has to have the last word.......so it will always go on and on and on. @ricevs I get what you are saying, and regret ... | |
| Red Plating?? To drop the AC line voltage inexpensively you can use a device called a bucking transformer. This is simply a transformer that has the required voltage (10V) along with the current required. So if the amp is drawing 3 amps you could use a 5 amp 10... | |
| Red Plating?? @georgehifi When you go from an autobias to adjustable (by definition both are considered 'fixed bias' as the bias is 'fixed' by the voltage on the grid), regardless of how the amplifier is biased, the output power is unchanged (the distortion cr... | |
| Class D It’s more about power, because you can’t see the forest for the trees, with what Mark Levinson tried to do by series up "low order" output filters (so they don’t burn out) and trying to get a steeper roll off as not to introduce phase shift int... | |
| AES48 , is there a test to determine? I have determined that my DAC and amp do not support the AES48 standard.If that is the case, you may not be able to run cables long distances and you might run into ground loop issues. But if there's no ground loop (which is entirely possible) tha... | |
| Tube amp Friendly Speaker That Sounds like Klipsch Cornwall I'm guessing budget plays a role?I run a pair of Classic Audio Loudspeakers model T-3. 16 ohms, response to 20Hz, 98dB 1 watt/1 meter. 60 watts is plenty of power on them in most rooms!You might consider another alternative though. If you were to ... | |
| Never Owned a Tube Amp and Want Advice @dsper Ask him if he can wire the woofers in series rather than parallel. It will require a little bit of adjustment in the crossover but otherwise the math of the drivers in the box is exactly the same. Contrary to popular myth, the woofers will ... | |
| Red Plating?? Would you consider the red plating shown in my photo a "bit"?@chinook9 Technically this would qualify as 'a bit' :) It would certainly have me nervous! I would contact the manufacturer of the amplifier. | |
| Class D The amount of power the filter has to contend with in Class-D amps compared to a dac, now your showing how ridiculous your statements are.This statement is wildly incorrect! Although digital and class D amps both employ switching, it is important... | |
| AES48 , is there a test to determine? It was partially your high opinion of the HPA4 that lead me to try purchase one. Since the HPA4 is AES48 even though it has both balanced and single ended outputs without a switch (please comment Ralph)Without a look under the hood I suspect tha... | |
| Modern amp solution for Magnepan 2.7QRs with bluetooth and phono stage interfaces? If you get separates, which often work better with Magnaplanars, then what you need would be a power amp for the speakers, and the bluetooth and phono functions could be handled at the preamp level. But any preamp would do fine if a bluetooth rece... | |
| Red Plating?? Interesting, the manufacture designs an auto bias amp around the kt88 tube and then recommends the user to use 6550 tubes. Functionally they are nearly the same. No-one makes 6550s anymore; KT88s work in all the same places. But a 6550 will be a v... |
