I didn't know if this was like a 're-cap job' where you were simply trying to do 'preventative maintenance'.

Be aware that if you cannot source these from a reliable/reputable distributor (VERY few on ebay, many counterfeit parts), you may have to use a non-encapsulated part with appropriate insulators/washers to make it reliable.

Digi-key has the 4024.
 
I never blindly re-cap an amp. If you see caps serving a particular duty that look damaged or a particular series of caps in the amp that have a high failure rate, that's different. Too many people replace too many good caps and get only imaginary gains.

After you get the transistors out, double-check all of the resistors in the drive circuit to make sure that all are within tolerance.
