Urei LA4 question
Hi All
If some one could please help me. Looking at the schematic of the LA4, it shows two LED's optically connected to two LDR's. Are these just ordinary LED's can i assume yellow? Or are they some other unusual light ? Does anyone have an LA4 that they could photograph the insides of? i am thinking of toying around and making one, just as a project, and seeing the insides of one would be usefull. Also does anyone know anything about the output transformer. the seconday winding would have to be 600ohm impedance, but the primary impedance?? If anyone could help i would be really greatfull. Many thanks Jules |
