Hi Todd! Thank you!
I live in Europe with 230V, so I think it should be 2.5A and 250mA for X1.
I already bought fuses.
Less expensive ones. M-2 are supposed to sound organic, emphasizing emotional content. For X1, L1, A1.5. I chose Ampere values as listed below. Hope this will sound good.
I’ll put them in next week when coming home.
Imo the data sheets doesn’t help with direction for fuses of X1.
Hi Engadin:
I also live in Europe and have an X1, L1 and A1.5. I am planning to change the fuses also, and considering QSA Yellow or SR Pink. In the notices, the A fuses are referenced as T50am/250Vac. Could you please advise whether you bought Slow or Fast blow for these ones. Thanks.
FST and SPT are Schurter fuse series. To the best of my knowledge both are “T” meaning “träge” or “slow”.
So I chose slow. I have not looked at the caps of the fuses in my 230V CH P units.
But I am pretty sure they are slow.

I can say with absolute certainty that the main fuse on the L10 is a slow blow fuse. if you install a fast blow fuse it will blow upon powering on the preamp. I found this out when the wrong fuse "speed" what shipped to me and I installed it. And since L10 and X1 are under the same heading then the X1 main fuse is also slow blow.
AM M2 fuses in L1, X1, A1.5 were helpful.
They augmented and improved bass, body of instruments.
They improved fine nuances, in recording room recreation, palpability of instruments.
Higher resolution of the material of instruments, textures, overtones (things CH P had already done very nicely before).
Most of all, they enhanced fine dynamic shadings, the things to make a singer fascinating or boring.
Music has become more captivating, more fascinating.
Before the M2 I hardly listened to singers, as they had been boring.
This did change.
I own a few ECM boxed sets of jazz bordering “free jazz”.
I hardly ever listened to these discs.
I tried one. Somehow interplay suddenly had become meaningful and I could enjoy that.
These fuses didn’t make spectacular changes,
Would QSA have done a lot more?
I guess so.
Nevertheless, I do like what the M2 do.
