Tom Evans Linear A

What is the value of the power fuse in a Tom Evans Linear A amp and where is it located?Bought the amp without a manual and would like to upgrade the fuse. Thanks.
Amp is made in Wales and hifi tuning fuse works great. Fuse is located need to power plug in rear and pops out with a knife. slow blow 2a I believe.

Amp is fantastic in my opinion! I upgraded the speaker posts and psu mosfets thru Scott Franklin in san jose who is Tom's only US rep.

Bob, thank you so much for your response. It is a big help!
