Unless you know how to safely discharge caps, I wouldn't risk it. They can hold a charge for some time. Don't mess with them unless you know what you're doing. Also, everyone should not panic over point-to-point wiring with a star ground. A star ground uses individual wires to connect ground to a particular ground point. It results in extra wires, however, it is not inherently unsafe. I'm not excusing Mikhail's work, but do not equate wires running around with poor build quality. The opposite can be true with a carefully constructed amp. Personally, I think that star grounds are a great way to build an amp and can provide a measure of safety over using an exposed ground bus. I have radios and test gear built this way that have been operating safely since the 1940s. It's a good construction technique when used properly.
