Spectron Musician trun on noise / tweeter hiss

My Musician III SE MK2 with the vcap / bybee upgrades was just delivered and after setting it up and hitting the power switch a cracking static was momentarily heard from my speakers. The same was true when the power is turned off.

I realize that most amps generate an audible hiss that can be heard when you put your ear near the speakers tweeter, but the Spectron seems louder than most.

Do other owners share the same experience??

yes and so? Don't turn on and off your amp and the hiss can be due to variety of reason one of which is truthful amplification of input noise....

What are your impression of the amp?

My understanding is that you are supposed to leave the Spectron amp on 24/7.

Regarding hiss, don't know what equipment you are using, i.e., preamp.

Finally, Spectron has always been very helpful, heck you can't get Simon off the phone once you get him. Call them and they will help you out.

I have the Musician III SE and I don't hear any hiss. And I am with Rafael...what's it sound like in just the first day?

Tmaple I have some questions for you;

#1 Once the amp is on how far away can you hear the hiss?

#2 Is it just a hiss or a hum? of any sort?

#3 What is your accociated gear?

#4 IC connections, balance or single ended?

I have the Spectron Muscian III SE. On turn on there is a momentary crackle. nearly inaudible but its there. The same is not true of turn off, just silent. I have absolutely no hiss, even with my ear right up to the tweeter its dead silent. Try disconnecting everything else in the chain and listen for the hiss again, 10 to 1 its NOT the amplifier, but something further up-stream
