| Voltage conversion of Accuphase A-48 correct observation imhififan, Accus have different wiring colors, despite generic schematic is the same. not sure about resistance, using power VARIAC transformer starting with 0V AC and measuring major operational voltages (for example large cap... | |
| Decent preamp XLR is balanced (differential) signal path connection, and therefore immune to many kinds of EM noise. Used high end reliable preamp for 40% of new price is good deal, it can run almost forever. New ML preamp cost five times more, with comparable ... | |
| Decent preamp Mark Levinson 326s preamp is worth to look at. Phono option boards is still obtainable. | |
| Voltage conversion of Accuphase A-48 to verify correct voltage can measure voltage on large capacitor terminals, which should be in a range 50V to 55V | |

| Final Retirement Amplifier-Class A-Upcoming Gryphon Essence Stereo vs Accuphase A75 For moderate sound levels you may also consider Accuphase newer amplifiers A-48 (Class-A) or P-4500 (Class-AB). These are using the same input amplifier stage as expensive A-75, and therefore have excellent noise and speed characteristics. In inte... | |
| Accuphase C2420 + A47 I have paired Accuphase P-4500 with C-2420, and found sound is absolutely warm, air-trasparent, and basses dense. I am using Accus to drive custom 3-way 8Ohm speakers, 30..25000 Hz, 89dB/m, and less than 1% distortion. New P-4500 design seems is v... | |
| Voltage conversion of Accuphase A-48 All Accuphase amplifiers and preamplifiers I’ve seen use the same transformer type for US/EU/Japan markets, and therefore it is relatively easy to switch them to desired voltage. |
