Hi there!
I'm trying to repair a damaged UA-5 unit. It does not power up, and the power stage seems to be damaged, but I'm trying to find an schematic of the circuits of the UA-5 to try to figure out what's the behaviour of the unit, so I can locate the damage, and then, try to repair it.
Anyone could help me?
Has anyone repaired an UA-5 with good results?
Thanks!
