One thing that comes to mind is that you are using a 5Y4 instead of a 5X4 tube. They are not rated the same. 5X4 has more current capacity for one thing. I always want to make sure I have the correct tubes in a radio before I power it up. I went to the frank.pocnet site to post the specs here, but the site was not loading at the time.
In your case the previously mentioned advice should be followed before powering up again. I would take an ohmmeter and look for a shorted cap or low resistance on the B+ line. Cap in backwards? Also, I’m not sure what type of caps you used to replace the old electrolytics. On this set 500 V electrolytics are the minimum I would use. In fact, the best choice would be 630 V film caps, Solen Fast Caps from AES.
Keep us posted.
