Hey folks,
In trying to troubleshoot my MP-1 (reversed dist/clean channels), I re-awakened my MP-1 obsession and desire to fiddle around with my soldering iron.
I spent today poring over schematics, websites, my MP-1's innards, making a list of components to replace to "refurb" my unit - replacing *all* the electrolytics, replacing audio path resistors with metal film, upgrading opamps, etc.
I'm having an issue finding appropriate coupling caps for C3, C9 and C10 (6800 pf, 200V) and C5 (1500 pf, 200V) - these are the blue mylar caps on the tube board, my C5 looks like a bigger version of C3 in the attached pic, not the white box C5 in the pic) - most of what I can find aren't dimensional matches or don't look the same.
I was looking at Orange Drops, they seem kind of big - but if I bend the leads, could I make them work? Doesn't matter if voltage is over spec, right?

I also found these, but they aren't stocked...would this type of cap be even better?

I'd like to replace these 30 yr old components with the best available at a reasonable price, and since I'm placing a rather large order I figure I may as well get everything at once.
Generally speaking, if the capacitance is the right value and the voltage rating is at/above original spec, as long as the leads fit it should be fine (assuming it's the right type, of course - I wouldn't put ceramics in an audio circuit for example).
thanks in advance (and yes I'm learning by doing...any recommendations for a good electronics starter book for theory/concepts?)
