The P10 Phono stage was awarded the top accolade of 5 globes in the. See if you can find someone local to provide some guidance if possible. We make tube amplifiers, passive preamp and speakers, and supply parts for DIY Hifi. Dikes, needle nose and good wire strippers are a must if you are serious.ĭo some reading on basic electronics theory and troubleshooting as well. Get yourself some good tools from Mouser/Digikey including a decent solder iron. On a more constructive note do you have a good multimeter, and can make a mains ballast lamp to test whether or not there is more to this than a blown fuse? (The ballast lamp is wired in series with the ac power to the device to be tested and in the event of a circuit fault will limit the power to something reasonable if the right size bulb is chosen - in this case I think 25W is a good starting point.) (And I spent 15yrs + designing consumer electronics professionally so my fuse comments are based on typical design criteria for these devices.) Indiscriminant replacement of a blown fuse without understanding why it blew in the first place could well lead to further damage to your unit.Īs an aside I have a lot of component audio and video gear that is pushing a decade or more in some cases, not one fuse has blown to date. 12/2007 - Aurum Acoustics Integris CDP CD Player/Preamplifier (Review Follow-up). (In a small number of cases a fuse that is marginally rated and/or is quite old may have thermally fatigued due to many inrush cycles and has failed, a tech will know how to determine this.) Amongst other things you could have a failed transformer, shorted rectifier, filter cap, or regulator IC. Fuses are generally provided ONLY to prevent a fire hazard in the event of a component failure, if properly chosen they should never blow in actual use.Ī blown fuse is generally a very good indication that something significant has gone wrong.
