Finally got my hands on a CS300. First impressions were... not great to be honest.
Really thin sound. The fact that I have no proper source and had to go straight from
the computer (with a ESI Juli@ soundcard, but still) might have something to do with
that though.
Brought home the Compass from work, so now I have a Stello U3 -> Compass -> Leben.
At least it sounds more or less as it should... will of course upgrade the source ASAP,
I must have the crappiest DAC of any Leben owner
Anyway, got some issues with it that I hope you guys can help me with...
* About 10 seconds after turning on the amp, a hum appears in the right channel.
This is with no source connected at all, so it's definitely coming from the amp itself.
No change in the sound when changing the volume, it's a constant hum, not very loud,
but still annoying and clearly audible during quiet parts of the music.
I'm guessing this is down to bad tubes? It's a second hand unit, no idea how many
hours the tubes have done.
* There is also some hiss that is affected by the volume control. This is my first
tube amp, I'm used to the deep silence at all volumes from SS equipment. Is this
something I should get used to, or is this because of faulty tubes / a faulty unit?
* Lastly, any tips for decent tubes that aren't too expensive? Any good source
for tubes besides eBay, that sells to Sweden?
