Drake 1202-304/4 power transformer for a 1985 JCM 800 50 watt

[24 track]

I did a cap replacement on a JCM 800 using 50/50 uf F&Ts this amp has been in storage for a lot of years , trying to test this puppy there is no current getting to the tubes what so ever , 120 volts a/c going in , all fuses are good internal and External but no power or current reaching the tubes. I suspect the power transformer is which a Drake 1202-304/4 . Does any one know of a direct replacement for these? , Mojotone has one but is out of stock, I tried looking at Hammond , but there is no cross referencing to the Drake parts. is there any thing Here I am missing?

Did you meter the transformer outputs?

never mind

Did you meter the transformer outputs?

not yet I haven't found any specs on that transformer the diagram I got above was from MOJOTONE that claims to be a drop in replacement and is it so far, all of the contacts in the amp are covered with a yellow tamper proof paint from the factory that make it more difficult to just meter properly, the High voltage board which is over the transformer contacts does not indicate voltages across the fuses , yet the fuses all have continuity, so far

The original transformer had these colours for the primary windings.
Common - Blue
110v - black
120v - brown
200v - red
220v - orange
240v - yellow
Have you got mains going in?
Have you any continuity between the primary windings?

This will give you an idea of what is what;

Perhaps only 75mA HV coil output is a mistake?
