Powered it up late last night and found that off/on switch isn't working, was kinda stiff before so will have to give it a good cleaning. Hot wired it and got power. Power supply is working fine but radio has some issues. Volume is low and no reception just background noise. Fed a 460kc signal down the IF and seem to be working. The LO I'm not so sure as I'm getting several oscillation and it doesn't seem to be mixing. Did use the generator for the LO and was able to tune in some stations but where nowhere near where they should be on the dial.
Going to focus in on the audio/det stages to see what is causing the low audio and the osc/mixer. Maybe an out of alignment issues but most of the time I'm not that lucky!
