You can measure what’s in there and see what value they really are. Electrolytics can vary up to 20% depending on spec. You can ask Sonic Craft to match the caps as close to 55uf as possible.
Yes, use bypass caps for sure. You can use a cap like Audience Auricap XO, Clarity CSA, and Jantzen Superior Z. Make sure they are high enough voltage for your circuit. 1-3 uf or so is fine.
