A 1209 is a low end Dual. Not high end. Google Dual. There is a web page for Dual. All models listed with specs. Serviced a few. Not bad. Wow and flutter is higher on a 1209. Have a 1219,1019, and a Dual built PE 3046. Wow and flutter are .06,.10 and .12 respectively. This spec measures speed variation. All three are hooked to one system so I can compare. The 1219 and 1019 are good for classical music. The PE you can hear the sound wavering with a classical piano piece. It’s good for rock,country, or jazz. Since it was destined to the landfill, I rescued it. It’s cam the runs the auto cycle was completely frozen. New stuerpimple. Have had it 6 month and it works flawlessly. Replaced the sled with a new BEST sled using a. Shure M91ED.
Back to OPs 1209. Though a low end model, have serviced several. Fewer moving parts. Regreased and cleaned/oil motor pretty much good to go. Fixed up a beat up wood base. Had several I did during the pandemic. Made several plexiglass dust covers. Service that 1209. Once done it will run a long time. My 1219 pictured I did 9 years ago. Another one has 6 years on it. Enjoy.
