Cronos Magnum II

New to the group, amazing amount of information.  My Rogue Audio Cronos Magnum II is about a year old and it blew a K120 tube about a month or so ago.  No big deal, I ordered some back-ups but today one of them blew again and this time with a certain amount of fury.  The port looks like it was on fire, the tube glow was intense then soft, then intense etc.  Pretty significant pop in the speakers also when I turn it on, even before it warms up.  Anyone ever experience this?

Thanks.

If you have TWO tubes go like that in a row : best to send back to Rogue or a qualifed hifi repair guy.  Don't keep popping tubes in it - at some point you'll possibly start blowing resistors etc and things will start to get more fatal and pricey.

Thanks.  We just moved and I did not bias the tubes upon set-up so that’s likely the issue.  Also blew a small 1/4 amp  glass fuse so need to source that also.  Looks like an amazon deal since that size is near impossible to locate.  Thanks again.

Give Rogue a call. I found them really helpful a number of years back.
