Here is a set of audio transformers restored with new resistors and upgraded to handle more than 15W power as later standard. Those Erie resistors getting high resistance values. fore example a 180K resistor is measures over 220K and I decided to replace them all. Also the weak banana jacks where replaced with some high quality German manufactured ones (no need for drilling). Protection units for the treble panels will start clipping over 2,2KVolt. Original Erine caps used when possible.
