Granted my cams cost four times as much as yours... I'm not fond of reworking the same box, even if it's ten or fifteen years down the road. The original caps were 200MF at 450V, I could have gone with those but wanted more available peak current and better regulation. Better regulation means two things; Higher average power (not that important and not my concern) Lower distortion of the output signal. (my main concern) Keep in mind one important thing, I wouldn't go with large caps in your application due to the age of the transformer. I can get a replacement for my SB-220 there are a number of custom made replacements out there all the way from one that is a drop in replacement rated at the same 600VA as the original one, to a 1500VA transformer that fits in the same spot with minor modifications to the internal side panel. Your radio will see some use and will sit in a museum and should remain functional for those times when it is taken out for a spin on the bands. I would be very proud to have an SR-2000 and it would not see daily use. (They don't take the Star of India out every weekend and race it, and they certianly don't take it out in bad weather) So for a number of reasons you wouldn't want the same cap, They do offer a cap in your voltage and capacitance range that is very reasonably priced that has the same low ESR. In short you restoring a classic. I am building a daily driver.
