Vox Galaxie (from Crown Organ) is too quiet

[posegate]

My Vox Galaxie amplifier (1960's) is far too quiet.  There is some sound coming through, but not enough to be heard over a two person conversation in a library.  The tremolo effect works properly, and the light bulb lights up.  The fuse is good.  Any ideas on how to troubleshoot this?  It's too good looking of an amp (like an upside-down pyramid) to not use.  It's also heavier than my garage --weighs a ton!

Have you tried using a different speaker?  Sounds like the voice coils may be worn out really bad on this one.

There is an aux speaker output.  I'll give that a try tonight.  Any other ideas?

Okay, I tried two things.  First was plugging into the "boost" speaker.  This was just as quiet, but with two speakers.

I pulled out the speaker and tried a different one.

It was louder, yes, but nowhere near the what the 35 watts should have sounded like.  

Further suggestions?

Found someone selling one on Craigslist for $750!  I don't think I could ever get that amount.  Seems like a ripoff.

Of course, maybe the footpedal is worth $700.... that must be it.

Are the controls scratchy and do they seem to have intermittancy?

It might be just a dirty contact or a failed solder joint.

It's likely not anything serious since the fuses are intact.

Open it up, do a visual inspection and some cleaning. If that doesn't help or locate the problem then start testing the components.

I see a little bit of oxidation at some of the solder joints that are visible.  Is this what you mean?  See the twitpics posted above.
