Silvertone 4590 help

I am working on a Silvertone 4590 Console Radio. The audio output transformer is toast and the power transformer has been replaced as well as a 5U4 in place of a 5Y3.

I replaced the power supply caps and have 300vdc with approx 1vac ripple with 1 amp input current.

I tacked in a Stancor A-3880 universal output transformer and the 300 volts drops to about 170vdc. I removed both 6N6s and the B+ returns to 300vdc.

I've been using the schematic for the silvertone 4587A as a reference. Is there a schematic for the 4590 to see if I'm missing something?

Thanks
