today the simple se said his first words ...

first of all he is dead silent

I;ve only listened him for a couple of hours with triode mode and not in high volume (kids are sleeping)

the sound is just amazing (my poor English dont help me to describe what I heard)

never believed that my first build would be so good ...

oooops,

suddenly a strange noise came out from one channel, i turned it off for 10 minutes and when i powered it again there were sparkles in the rectifier tube and a blown fuse .... replaced it and happened again ...... no more fuses left so I have to wait untill tomorrow to get some more (probably bigger ones , 5A instead of3)

any ideas for the sparkles ??

I wouldn't use 5A fuse. It sounds like power capacitor may be at fault. There was a mention of this symptom on older thread here. Try search function with "simple se fuse".

Don't use a 5 amp fuse. Don't use a 3 amp fuse, either. 2 amp fuse is plenty. If something is wrong, you want the fuse to blow.

Your 5AR4 rectifier tube is done. It has arc'd out, and will never be good for vacuum tube service again. You will need a new rectifier tube.

There may be rumors floating around that JJ rectifiers are not particularly well known for their durability. Lots of early failures and that kind of stuff. I'm running an older Sovtek in my Simple SE right now. I bought it about ten years ago. I've also used Chinese 5AR4 in my Simple SE with success. Maybe they were Shuguang, or maybe they were Sino. The label on the side said "Ruby".

Old 5AR4 made in Gt.Britain and Japan (Philips, Mullard, Matsushita) are well known for their reliability, but they tend to command very high prices in the used market.
