Thanks Ron. I ment to say 250 vs. 280 but forgot. The reason I was asking this was that I have a 280 I've been working on which won't put out any sound and recently acquired a 250 which does work. In comparing the 2 I found two spots where the capacitors are installed differently so I made the 280 like the 250 but no change in my problem. O well I'll just keep plugging away and hopefully I'll find the answer.
