A- Black (goes to chassis)
B+ power Blue (goes to speaker)
B+90 Brown
B+ Det Yellow
C- Grey
C+ Green ( goes to Chassis)
And one red lead which goes to one side of the heaters the heaters would this be A+?
Also don't see a B- ?
It looks as thought I will need 3 voltages?
A, B, and C How would they be connected?
and at what voltages?
The tubes are 5v heaters 5-01A and 1-171
Any help would be greatly appreciated!
