| Watts! How many do we need? @jfrmusic spec with design details for p4600 https://www.accuphase.com/cat/p-4600_e.pdf | |
| Power Cord for Accuphase Amplifier @audiophile1 "And who inspects IEC connectors in their components under the microscope? “ ppl who care about value of their gears? | |
| Watts! How many do we need? @jfrmusic 6 transistors / leg, 12 total pnp-npn power devices per channel. I calculated A class wattage using p4600 schematic. | |
| Watts! How many do we need? @jfrmusic I looked amp spec and schematics. A/B class P4600 increased idle power and number of output transistors to 12 in each channel, matching their A class amps. 20W is estimate of peak power for linear output transistors range, for both chann... | |
| Watts! How many do we need? @jfrmusic Accuphase output meters are accurate, you drive y’r amp at very low power, accordingly to Accuphase design P4600 is a class A amp till ~20W. You may crank it up to the max to see full power range! | |
| Watts! How many do we need? @jfrmusic not sure about OP question.. Accuphase P4600 (congrats, it’s a good amp!) has output power indicators, which should help you to determine if you reach limit and need more Watts! | |
| Power Cord for Accuphase Amplifier @audiophile1 "No plugs will scratch the IEC connectors" as an experienced analog design engineer I can say this is not correct! typically product from established hi-end company chooses IEC receptacle and plug (or assembled cable) from one compan... | |
| Power Cord for Accuphase Amplifier @jfrmusic "Accuphase strongly recommends that you use only the stock cord and so far that has been the best" why not to rely on on Accuphase advice and to start enjoy music? Accuphase Engineers choose carefully IEC receptacle for amps and cable ... | |
| Upgrade My Turntable - How Much Do I Need to Spend? @hikerneil "The SL-1200G is an absolute beast” +1 & Congrats! -the only one’ beats it is Technics SP-10R + EPA-100MK2 arm, in SH-10B5 plinth.. | |
| Power Cables @jfrmusic "Just finished burning in my IceAge Frankencable power cord" power cables don’t have much aging effect, unlike tubes, some heavily used semicons, electrolytic caps, and hard driven resistors. there is some change in contact resistance, ... | |
| New expensive power cord for amp and no change in sound? @ audio.. "I have noticed the most improvement on digital devices using better power cords” -more details, such as digital device name, original power cord (not known?) and replacement details would be nice! | |
| Revisiting Chinese Knockoff Cables @zigstien got similar cable, re-terminated with nice rhodium plugs and voilà! All measurements after some work around came perfect (R, C, L, all at 50-50000Hz)! I don’t take those cables as clone, it’s more like good material for DIY project. Good... | |
| New Accuphase Amplifier Experience lalitk, I see you have E-650 integrated, which is class A amp. class A amps have relatively stable current at different sound volume level, which helps to reduce transient current in incoming power, thus amp self-induced voltage drop is minimal. m... | |
| New expensive power cord for amp and no change in sound? "Why do you guys care?” .to share our own mistakes and best methods, is it wrong? | |
| New Accuphase Amplifier Experience @jfrmusic C-2300 pre looks cool! four freq. tone control is interesting! I decided a while ago to buy excellent quality analog or digital devices, not mixed ones.. analog stuff these days “never get old”, while digital units age very fast :-). |
