Over the weekend, I replace the two internal fuses within a friend's CJ LS17 preamp with the hifi tuning fuses and the improvement was huge and beneficial - adding both depth, soundstage, and air to the music. At least as much of an improvement as connecting the Shunyata Helix Alpha powercord, and, the improvements were additive - both devices helped.
Now, I am looking to replace the fuses within my CJ CT5 preamp and in a pair of CJ Premier 11a amps. In the latter, I am hoping someone out there more knowledgeable than me can advise which of the following fuses would likely be more worthwile in replacing - there are 7 fuses in each amp, times 2 amps, time $40 fuse - I would like to add at least a little sanity to this upgrade...
Per Ed at CJ, the Premier 11A has the following:
Externally accessed:
Plate fuse: Buss BBS 3/4 A
F1 main AC fuse: 3AG 5 A fast blow
Internally accessed: on the small PCB near the back of the amp.
F2 (near front of board) 3AG 4 A slow blow ( for secondary windings for filament supply(
F3 3AG 1/4 A fast blow (bias supplly)
F4, F5 3AG 1/4 A fast blow (low voltage supply for bias LEDs)
Your advice is appreciated...
