If your unit still has the original selenium diodes they definitely need to be replaced. While you’re at it you should replace some of the resistors that are under heavy load as they get tired and values drift. Not that it can't be done I've done a couple of complete recaps on these units.
There are no direct replacements for those cans which contain multiple caps each so you will need to replace them with discrete caps. The down side is that these amps are older than twice the life expectancy of the capacitors so they will all need to be replaced. You can add a few capacitors, resistors, pots and a couple of 12AX7's to create a reasonable amp. Without a Pre-amp stage the Amplifier is useless.
#CORDOVOX AMP AND TONEGENERATOR GENERATOR#
The tone generator cabinet contains the Organ and the Pre-amp circuits required to drive the amp.
The Amp cabinet contains the power supply for both the amp and the tone generator. If you want a single cabinet Multi-purpose amp you'll need to add preamp stages into the Amp cabinet. As a 2 piece set it is already somewhat of a general purpose amp. As you know, the tone generator already has high impedance inputs for Microphone and Accordion pickups. Making a general purpose amplifier out of your Cordovox CG equipment is a fairly big job if you want it all contained in a single cabinet.
