| Accuphase E-260 Voltage Conversion (100V to 230V) @frankhhh I believe E-270 basically has the similar connection, Accuphase changed the color code on E-270 primary winding wires from E-260. Sorry I can’t see the color very clear from your picture, please confirm if the setting shown on your pi... | |
| Is rectifier tube arcing a problem? Just like seat belt and air bags, more protection is better, IMO. However, some might think that put a silicon diode in a tube power supply is a sin! If that’s the case, you can install soft start alone. The soft start device is a CL-70 NTC ther... | |
| Is rectifier tube arcing a problem? Yes, I found a picture on the web that show the details You can solder the diodes on the socket and move the wires accordingly. you can use 1N4007 diode, but UF4007 is better (lower noise) and just cost a few cents more. BTW, if you interested... | |
| Is rectifier tube arcing a problem? @gte357s IMO, reduce the capacitor value will has a bigger impact in sound quality, those 220uF capacitors are mounted into a 35mm clamp with point to point soldering. You need to find a 50uF cap with similar quality and diameter to fit into tho... | |
| Is rectifier tube arcing a problem? And the amp section schematic | |
| Is rectifier tube arcing a problem? @atmasphere This is the power supply schematic at Steve Hoffman Forums, not sure if OP’s kit has the same power transformer (C core) and same component value? | |
| Is rectifier tube arcing a problem? I need to add two diodes per tube, am I correct? Yes. BTW, do not reuse the arced tube! Usually once a tube has arced It will continue to arc at that same spot on power up. | |
| Is rectifier tube arcing a problem? Soft start will help, you also can add an UF4007 to the plate of rectifier tube to removes negative half cycle voltage and it halves the total time of voltage that feeding the arc. | |
| Is rectifier tube arcing a problem? Add a negative temperature coefficient (NTC) thermistor on the primary side of the power transformer and bypass it with a time delay relay may help. | |
| Amp with RCA and XLR Inputs PLUS a switch to Select Check out Accuphase power amp, you can connect both XLR and RCA at the same time, good thing is the input selector switch is on the front panel! Bad news is their amp are big and heavy. | |
| Is the Schiit Magnius up to the task ??? I always use XLR connection if possible even for 3 feet run. IMO, XLR provide more secure connection than RCA. | |
| Isolation Feet for Laptop Unless you use a fanless laptop, otherwise don’t waste your effort. Cooling fan is the main vibration source. | |
| How to turn on Unity Gain on Pre Amp Tone bypass is not HT bypass, its function is to deactivate tone control setting. On the C2500, " Passthru " is HT bypass. To activate passthru, you need to sent a 12Volt single by an external source to the back panel "power control" "Pass-thru" ... | |
| Thiel Owners I think that makes sense. The Thiel sensitivity is about 6dB higher than the Kef (90.7dB vs 84.5dB according to Stereophile’s meansurement). | |
