Harman kardon a300 rebuild

Hi everyone. I’m replacing the can capacitors on my a300 with custom built caps from Hayseed Hamfest. The hot can (cardboard wrapped) is made by GE and its specs are printed on the can as 60-100 micro farads at 350v. I’m concerned about the range of uF as I need to specify a uF rating for them to build a new one. Should I specify 100uF or something in the middle like 80uF?

thanks in advance for your responses

I would do a middle of the road approach. If you keep adding uF to power supply filter caps you’ll increase the surge currents and stress the rest of the power supply on turn on.

Assuming you are reading this correctly, and the cap was specified as being at least 60uF and no more than 100uF, somewhere in between is fine.
