Oh no! There's another one of us that use's caps that are way to big! I've been using some caps salvaged from old computer p/s boards. Most are in the 200 to 300ufd range at 200v.I use some large shrink tubing over two of them and it's about the some size as the old 50/30ufd150V. Seem to work fine. Used some in an Emerson 707about 6yrs and it's still going strong.

To be honest I think the issue of using capacitors of a large capacity is exaggerated, or at least there is a law of diminishing returns when it comes to capacity increasing power supply output voltages. I think it's true if you replace a 2 microfarad capacitor with a 4 or an 8 but once you get above a certain point, lets say 10 mf, 15 mf, 20 mf, it doesn't make much difference, above 40 mf it makes no difference at all in output voltage. Some claim that bigger capacitors kill rectifier tubes quicker, maybe they do and maybe they don't, but anecdotally speaking I haven't had any problems that I can recall.
