There is a small chance you could fry any source device by touching it to high voltage...use something you don't care about or a test generator designed to take some abuse, or be extra careful in how you go about connecting it (dc blocking caps are not a bad idea).

I have an old portable battery powered tape player, but that's about it.
Also I tested the B+ voltage coming off of Pin 7 of the 35W4 rectifier tube and C2 (which is the first section of the power supply filter cap can), and according to the schematic it should measure 120v and I got about 130v, does that indicate anything problematic?
