Here we go again...
A few months ago I bought my first Stax setup. An SR-507 along with an SRM-1/MK2 to power it. The unit being an A series was likely somewhere around 30 years old... enough time for the electrolytic caps to have dried out. As some of you may remember I chronicled my search for capacitors and the steps I took to replace them and perform the bias and offset to get the unit back into running order. I plan to do that again here with the SRM-717 this time.
I just purchased a 717 which may be as much as 14 years old. I haven't as of yet been able to find any good pictures of the inside that would show me the voltages of the power supply caps though there appear to be 4 large ones which at a wild guess I would imagine are 220uf @ 400v. I have a mind to replace the caps with ones of the highest uf value that I can unless anyone thinks that might be a bad idea...
Does anyone know what the physical dimensions of those caps are and what their values are?
Does anyone have any suggestions for other mods that I should attempt while im poking around in there?
