Problems getting the amp back into the shell

mace · Dec 4, 2024

Hi all,

My Mark VII is being a bit of a problem child and not wanting to get into his combo shell. It looks like the Tolex on the inside side wall (wrapped from the from to the inside) keeps bunching up. I’ve cut the small amount of loose Tolex but the. It just happens again when I slide the amp in.

Of only the edges of the amp faceplate had a small radius or bevel that would help. The edges of the face plates are quite sharp and unforgiving. But I’m not going Dremel on the faceplate. LOL So, I need to get the Tolex to stay put somehow, or make it easier to slide over.

Any tips or tricks for how to get this thing back together?

Slide a thin piece of cardboard in between the two.

Thanks for the advice. I ended up going a slightly different route. On the inside of the shell I trimmed both sides of any slightly loose Tolex using an exacto knife. Then put on a very thin bit of superglue where anything was loose and pressed down smooth with a small piece of wax paper. Then put a single strip of electrical tape across the entire width going from wood to Tolex (basically acting as a piece of cardboard would, to guide the amp over the Tolex). The amp slid in right to the top!

I can see that being fun to get into that combo shell. The head is just as much fun but at least the face plate can be removed if needed (unless you have a hardwood cabinet). Trying to get the power cord back in was more of an issue for me. Tried assembly with and without the power cord attached, was easier to assemble without the cord in place. Chassis removal with the Mark VII or JP2C is about the same as is the difficulty getting it back in. Not something I will do often. Not sure if the cardboard trick will work though, the internal load resistors are not internal, they hang down at the front of the chassis.
