Agree with what Jafox recommends and I would add that if the unit has not been powered up for several months/years the cheapest insurance is to power it up slowly using a Variac. The advice I got was to start at 10% voltage (i.e. 12 VAC) and increase every 10-15 minutes an additonal 10% until full voltage is reached. This will reform the capacitors and prevent a catastrophic failure. I'm not saying you will have a catastrophic failure if you just plug it in, but like I said it's cheap insurance!
Audio Research PH3 service, upgrades
A friend has a stock audio research ph3 phono preamplifier. It has not been powered on in a few years. My tech advised against powering it up prior to replacing some of the capacitors. The unit is super basic inside; I am interested in knowing of PH3 owners that have upgraded their units and/or simply serviced them in general. What brand e88cc/6922 tubes sound best, what capacitors, resistors, etc?
thanks in advance for any information
