Voice of Music 1448: filter cap values, diodes and fuse replacement

I am finishing the recapping of my Voice of Music 1448 and I have a few questions:
- I replaced all can filter caps, the main one is a 80/50/30uf as I don't find locally anything near 80uf I used 100/47/33uf, is it good anyway? I know that for the first cap is better to stay close to the original value but if I got it right this rule is for tube rectified amps, so as the 1448 is diodes rectified I think it's not a problem to use 100uf instead of 80uf, can I do it wihout problems?
- to replace the two old diodes may I use two 1N4007? No resistor must be added neither other changes are necessary when doing this replacement?
- I would like to change the fuse too, which value would you advise?
Thanks
 
If you add a thermistor to the power line you can probably use a fast blow fuse, otherwise they are prone to failing on power-up. Slow-blow for no thermistor.
