You might want to do a visual examination before you plug it in.

One thing I would do to make it easier to use would be to get rid of those Edison Price Music Posts- if you don't set them up right they can be a nightmare. I'd replace them with Cardas posts; to me they are a lot easier to use.

The Edison Price was designed to be able to clamp very hard on a banana post inserted into to it. If you plan to use regular speaker cable lugs though, the bananas still need to be in place, otherwise you can't tighten them down without damaging the post!

I would also examine the filter capacitors in the power supply- if any of the vent plugs near the cap terminals are not perfectly flat I would replace the capacitor(s). Usually this is a little red or gray plug a bit over 1/8" across.

I would also look for any resistors that appear discolored; if you find any replace them.

Finally, the output section should have some fairly large resistors on the tube sockets, 2 per socket. If there are not any there I would think about installing them; they would be on pins 3 and 6 and would be in series with the wires that otherwise connect to those pins. If they are there, I would measure all of them to make sure they are good. Further, the value should be at least 1 ohm (2 or 3 is better) and they should be at least 5 watts each (all the same value of course).
