PS conventional wisdom these days with vintage amps, is to remove the original speaker and replace it. Old amps will last forever if properly maintained, but old speakers don't, Sure you could use it till it blows and have it re-coned, but replacing a speaker will allow you to preserve the old one, and in some cases also allow you to put something modern and more efficient in it. My Princeton has a much more robust speaker in it than the original with better db rating and the amp is louder as a result Bill On Aug 18, 2014, at 8:39 AM, bill walker <wildbillwalker@icloud.com> wrote: > it is passive and it wants to see a 4 ohm load, a 16 ohm load will more > than likely make it run less efficiently, and could eventually harm the > amp you are using the other thing to consider is the age and efficiency > of that 10 inch speaker in the vibraton which is getting old at this > point, the paper is very dry and I doubt the speaker was very efficient > to begin with.
