electrolytic cap specs

I replaced a "can" e cap with individual electrolytics. The can had 3 caps, two were 20@450, one 20@30. The schematic shows one of the 20's as 10@350. I have a 20@450 installed where that 10@350 is called for. Is that a significant enough variance to make a difference in audio? The radio is a Motorola 61C. I got it playing, albeit with weak audio and distortion at higher volumes. The tone control had been wired incorrectly and a cap was missing on another circuit. I still have a lot of tracing and checking to do. Swapping power tubes didn't make any difference in the audio.

Thanks for your help.

Using a higher voltage rating cap won't improve power, but, it won't harm it either.
That's fine. Sounds as if you have an audio issue of some sort.
Check your wiring against the schematic.
Also, check all your tubes. May also be a bad tube.
