Ron, you might try reversing the leads to the 36 cathode winding or the plate winding. If you rewound the coil, depending on the phase relationship of the winding you may be applying negative feedback rather than the positive needed for oscillation.

At least it might be worth a try before considering converting to the 6A7?
