A few years back I found an original Intellivision console in a antique shop for only $10 so I bought it. Got it home and it wouldn't power. I cracked it open and found that the transformer was shot. Long story short I tinkered with other transformers to no luck and then shelved it. Well today I took a run at it again and I've made headway. The transformer has been replaced and now the power board outputs are mostly in spec. The 5v, 12v and -2v register fine with my multimeter but the unregulated 16v reads as 33v when tested with my meter. Is this acceptable when the power plug going to the main board is disconnected and the only load is the multimeter? I don't want to hook the power circuit up to the main board and blow it. I know unregulated lines give a wide range of reading depending on the load connected. Is the 16v line 16v when the system is running or just the base output with the cable not connected to anything but a meter?
Btw: Nice forum
