Though
most Marshall products are well designed, one has to be a bit wary on
removing one of these from the case. The four large M6 bolts obviously
hold the chassis to the back panel but, the six smaller screws down
each side of the top panel are simply wood screws. When you start to
remove these with the amp in an upright position; the weight of the
chassis tries to flip the panel outwards! This puts a big strain on the
screws as they are being removed. It is essential that the amp is laid
face down for removal. I personally would have used M5 screws here with
“Tee-nuts” on the inside, rather than the wood screws!
