Not really. Look how many times the B-15 was revised. The SVT, too.Hope you don't have to wait too long for the repair. Mine was in the shop for 9 weeks waiting for new boards from China. A new batch of boards made it to the US on November 19th. Rev G is the newest version. Others are commenting that they have Revision C, but that's just the sticker on the outside.
Amazing that Ampeg has gone through 7 different versions of the power board. Only time will tell if they got it right.

You see a heck of a lot of replaced power transformers on old B-15's. That was addressed in a later revision. The earliest speaker jacks they used presented a shock hazard. That was addressed pretty early on. I do not have a complete list of revisions and why, but those were two well-known revisions that needed to happen. What difference does it make? Most products get revised over time. A simple fact of life. My V4B from last year works perfectly, it's one of the very first off the production line, and before I even got it, there were some small revisions. Happens all the time.I'm interested to hear about the "many" revisions of the B-15 due to product failure. What was the design flaw and how was it fixed?

My thought was if my 7Pro went down I'd go for a V4B.Update: I Got a call from the repair shop yesterday. The tech said he ordered a new circuit board and that the amp should be ready in about a week. I had planned to buy an SVT CL and found a great deal on a like new one in a case but the guy sold it before I could get there...so now I'm going to give the 7Pro another chance and just hope it doesn't disappoint.
Missing out on the CL worked out for me though cause I was able to get a Sadowsky NYC PJ5.
