Well as far as the hum, replacing the the AC cable with a grounded 3 prong cable and plug will only make the amp safer to operate with other equipment. I think the point was brought up that the hum may be reverb related.
Unless a person has owned an amplifier from brand new, there is no telling who may have tampered in the amp or replaced speakers. That being said, a good visual inspection is always a good thing. Your amp may just have bad reverb cable connections as pointed out in this thread, to perhaps a broken wire inside the reverb tank itself, or a broken reverb spring, to a missing tank or replacement tank that won't work.
I tend to think you have larger problems since both reverb and vibrato are not working. All kustom amps with the exception of the K200A series amps, the effects work without a footswitch. The footswitch as StevenM said, you only need the footswitch to remotely turn off the effect.
The early versions of the K100-2 head had reverb so thick that even with the reverb gain turn down there was still a trace amount. I think Kustom did at least three revisions to that series of amp over the years.
Again after 40+ years, your K100-2 amp head could have been originally sold with the single 15 JBL D140F speaker. Music was a lot different back then and a guy could have been both a bass and guitar player so he chose the effects head with the bass speaker cabinet. Dealers were more interested in selling product. I remember country players would double up and a bass player and rhythm or lead player would buy a 2x15 cabinet and a K200B-2 effects head. Bass player would use the normal channel and the guitar player would use the reverb channel.
How times have changed.
