| Onkyo P-308 recapping/upgrading If it works, leave it alone.Kudos to that repair shop. | |
| Current... Yes.I = sqrt(300/8) x 2I = sqrt(490/4) x 2 | |
| I just bought a Steinway which sounds like a banjo. Even the cheapest of the cheap speakers will differentiate a Steinway from a banjo. | |
| Why would anyone want class AB amp when class A always sounds better ? Class A amps (almost) always measure better, not sound better. | |
| Other Rectifier tubes Alternative for 5AR4 The 5AR4 has a very low forward voltage drop for a given plate current. Substituting another rectifier may likely cause a B+ voltage sag which may affect performance. That’s probably why Luxman doesn’t give you other choices. Safety wise it’s no... | |
| Soldering Panel mount Rca There is a channel or a slot on the back. Fill it with solder and attach the wire. | |
| Rebuilding Power Amplifier(s) Without a schematic and test equipment you will have quite the challenge. Just like repairing a car, success depends on identifying the problem -- not throwing parts at it. In both cases you need diagnostic equipment to identify the problem and th... | |
| Power transition Look in your owner's manual. If it the voltage is field convertible, then follow the instructions. If it is factory set, then call McIntosh. | |
| Internal Wire Gauge? I don't know about other folks, but I try to avoid accidentally buying 300V wiring for tube amp builds. The wire rating I cited above is used by transformer manufacturers in their mains and output transformers. UL 1015 is not shielded wire; it is ... | |
| Internal Wire Gauge? 18 gauge for the power wiring to and from the mains xfmr and 20 gauge for the signal wiring to and from the output transformer. The wiring should be UL1015 listed (600 volts and 13 amps for #20 and 18 amps for #18 at 40 degrees C) | |
| Please Educate Me Suppose you send the same digital picture file to two printers. One printer kicks up ink residue and drips on the paper, the other doesn’t. The resulting output will be better on one printer than the other— even though they were both fed the exact... | |
| Dedicated power If you are going to get the Parasound HCA-3500 you will need two power cords since it has two 15-amp fused IEC inlets. So you must run two 20-amp circuits just for that. If you are going to get the Fidelity KW500, that has a 20-amp IEC inlet. For ... | |
| New at Qobuz - no HiRes sound "Hi rez" on Tidal is 16/44.1 unless you have the MQA option through your streamer app or or it comes with your DAC.Hi-rez on Qobuz is 24 bit 48 to 196k. The Levinson 30.5 has a 20-bit Ultra Analog DAC which cannot do 24 bit hi rez. I think that th... | |
| Suggestions for side wood panel selection / choice for a custom 2A3 build... Aluminum. Never steel for tube amps. Steel is magnetic and attracts leakage flux from the transformers and sends it everywhere to what's attached to chassis ground. | |
| Speaker Treatment To Resist Negative External Infuence Doesn't RF get through the driver cones? I think what you're hearing has more to do with the paint adding more mass to the cabinet. |
