Fuses in the 3 speed SME PSU


I have a model 20/2 table serial # 1173 and wish to upgrade the PSU with Hi-Fi Tuning fuses. There are 3 in the unit and my question is, which of the 3 are most critical to the performance of the unit as I cannot afford to upgrade all at this stage.

I'll never spend the prices SR charge. But I do agree that fuses make a difference. I tried a $40 Furatech rhodium but it was too bright/steely. 
Try this. I've done it and was amazed at the improvement. 
Wrap a few turns of masking tape around the glass part of the fuse ensuring it does not touch the metal caps. 
Worst case, it may indicate if the PSU responds to fuse adjustments. 

There are many ways to improve whatever fuse you have. We’ve covered this many times. You can even improve the performance of ordinary stock Fuses. All it takes is the energy necessary to get up off your BarcaLounger and a little uh, ingenuity. You don’t even have to be an expert Reverse Engineer. 🔙  As Bob Dylan is fond of saying at the end of his records, good luck to everyone! 🤗

hmm?
I have 11 Dylan mono albums and 7 Dylan stereo cassette tapes.
And not once on any of them does he say that......
You might be right, Uber. I’m just going by what Dylan said. Was he putting me on? 🙄
