Input switch is good, volume pot is good, continuity across the board is good. I am at a loss. Transformer perhaps?

There is no power at all that I can surmise.  No audible pop or hum. The bottom of the pcp looks like it has a lot of residual glue from the casing on it creating a haze which I will clean with alcohol and many of the solder joints dont look great so possibly will reflow those. Thank you for the suggestion of the input cutout contact. I hadnt thought of that. What is the best way to check that?

I have a newer pignose 7-100 and it just up and quit. Neither batteries or ac adapter will power it up. Any known issues I should be looking at? Thanks in advance for any and all help
