I am in the process of repairing a 42-395 for a customer that had plugged it in and turned it on before he brought it in. Therefore the Power & output transformers are cooked as well as associated wiring and rectifier socket.
One thing I do know is the transformer only has 2 secondary windings. It has a hv center tapped winding and a 6.3vac 4-5 amp winding. This unit uses a 7Z4 rectifier and 7C5 audio outputs have replaced the 7B5.
I would like to know how to calculate the voltages to find a transformer that will be close.
Any & all help is appreciated
Thanks
Jason
