PF-500 did I just make a mistake?

After reading some, not enough, reviews here I thought a low priced, used PF-500 might be a good deal. Then I found more reviews about these things dying, now I'm worried I made a mistake. Was it just the Rev C boards that were faulty, or are newer ones dying as well? I purchased it online from a reputable dealer, who guarantees it to work upon arrival. Man, now I'm bummed.
 
Thanks! I just really need a reliable amp. I wanted to stay with Ampeg. It's part of my sound. I'm sure it will work just fine. I'm a worrier.
It would have to be one from 2010 or 2011 for it to be a truly problematic amp, so the odds are with you. Not to say newer ones can't fail, but after the first year or so, reported incidents of failure drastically reduced on here.
 
A happy customer tells a friend; an unhappy customer tells the world

It was an old saying that predates the internet. Now it might be less true but it must be kept in mind when reading reviews.

IME I have never owned a PF-500 but there is one at a bar I play at. It’s been through 5 years of abuse by tons of bassists and it has never flinched.
 
How can you find the date of manufacture?

Should be able to tell from the serial number on it.
You can, though it's a little tricky. The date letter is in a different place depending on the model, and if they use other letters in the serial that could possibly correspond to a year of manufacture, it might be hard to tell which is which. Usually, it's somewhere around the 8th to 12th digit, and the code goes:

A = 2008
B = 2009
C = 2010

Etc.

For example. I know that my PF350 was made in 2011, and the D is the 8th digit. My Micro VR was made in 2010 and C is the 12th digit. My PF800 was made in 2013 and F is the 10th.
 
I bought a PF-500 early in their release history. It worked fine for the first 6 years, then went into fault after an hour or so of playing, and had no output. After it cooled down, it would work for another hour, and so on. The fan was operating fine, and it did not feel particularly hot, so it was likely a faulty temperature sensor. It was going to cost almost as much to repair it as it was to replace it. I really liked the amp, so I bought a new one with a new rev main board, after reading the newer revs are better. It's been working fine for a few years.

About a year ago, I checked into the price of a replacement main board, and found one for $189. I replaced the main board in my original unit with a current rev board, and now I have two that work great! You can buy new replacement main boards on Instrumentalparts.com. It's a very easy replacement.
 
A good friend of mine who tours all over the world uses an SVT for his main amp and has a PF-500 as a backup just in case he has a problem with the SVT. He leaves on top of his SVT so he can easily change heads if needed. He loves the PF and has never had a problem with it.
