1956 Symphonic record player - cartridge upgrade and amp modification

Here's a Symphonic "one tube wonder" record player that originally had a 3 volt crystal cartridge installed. Since those types of cartridges are no longer made and since the quality of NOS cartridges are questionable, I installed a modern .5V ceramic cartridge and added the necessary preamp circuit for the record player to perform it's best with the lower output modern cartridge.
