The PS doubler is working fine and all of the electrolytics along with the tubular caps are new. Before they were put in they were checked with an ESR meter and a capacitance bridge for correct and tight values. I tend to agree with you that the most suspicious site would be a heater to cathode short, but so far I haven't found it (or them). I've gone through the two major pc boards with a fine-tooth comb and haven't found anything out of the ordinary. Any other thoughts? Bear in mind that this set was assembled by a rank amateur a long time ago and I've already fixed an "arm's-full" of construction problems, but there may be more. Thanks for your comments.
