Was going through some of my old pictures and stumbled on these. Bought myself a Mesa Boogie back in the mid 90's, and it came with a design flaw. After playing a little while it would develop this horrid howl... Contacted Mesa Boogie, and yes they knew what it was about. Had to pull out the chassis and send it to them, and they completely replaced the board with a new revised board. From board revision SB1C to SB1D as seen in the pictures. They got rid of those epoxy components... Two week turn around time. No too shabby. Anyway, here are the before and after pics of the overhaul.
Hope everyone has a great weekend!
