Greetings all! Thank you all for the input on the broken tuning capacitor for my JEOL ECX-300 HF probe. It ended up being a 5240 JOHANSON variable capactor that I could get off a 3rd party website for $20 bucks. However now that I can tune like a champ I am having another problem. My Schomandl ND-D 500/500 Frequency Generator is on the frits. I am receiving 60Hz noise which can be removed with turning the clock to external. I am looking to see if anyone has the schematics so I can replace the responsible components.
