I'm sorry, I don't understand you. Are you saying that they are the Valves that the Service Data specifies? If so it's an odd mixture, even for GEC.
X61M is ECH35, which is International Octal. There's plenty of those about, along with it's 'CV' equivalent. A 6K8 would probably work as well although the Electrodes are actually different.

DH77 is 6AT6. Again, there's plenty of those available along with EBC90, it other equivalent. However, it's a B7G.
