Got my Altec 421A back from Great Plains Audio after they did a complete rebuild on it. Supposedly, the top 2 guys were long time employees at Altec and bought the stock when Altec closed, including the 3 inch aluminum dust caps, that are a little difficult to come by. Anyway, I've installed it, along with another matching Altec in my '72 Ampeg B25B cab. I actually used the cab and matching head in an audition session with a drummer the other night and was pleasantly surprised with the performance. So far, so good is the good news.
