-somewhat- knowledgeable(about TEK stuff),IMO.
There's a wide selection of TEK instruments I never serviced.
Spec analyzers,digitizing scopes,logic analyzers.Some stuff was "factory

But use a low profile HS that will not touch the cabinet.
Maybe even put a patch of insulating tape on the cabinet in that area,just
