Before using that signal generator as a basis for higher power square wave output I would repair it. The current output should be nice clean sine-wave with minimal harmonics. You have the opposite showing on the scope. Having been through that I suggest looking into function generator modules on Ebay, or similar. You can pick-up an very good FG for less than $20, even as low as $5. Then build an SSR (solid state relay) from a chip or two and a MosFET as an amplifier. The time you spend repairing that SG and then building an amplifier isn't worth the cost of buying something else. Sorry. Like I said, I've been through that. I have a couple of very nice old signal generators but never use them due to a few $20 Ebay'd FG's. Avoid buying an FG that isn't guaranteed to work. If you do, let me know what the thing is. I should have schematics for it. ------------- Just checked....... No Sanwa documentation here
