The filter caps should probably be 500V rated as (I am not sure, been a long time since) 290V DC is under load, so without a load I would think it could reach over 450VDC for 3-4 seconds when the rectifier starts and other tubes are not hot yet as it should be the peak voltage which is 290V*3.14/2 = 455V.
Thanks Morzh - I didn't know about those bakelite caps before. Glad to see your thread about them. Guess I'll need to do that as well.
