Fiddling with the tubes
01/17/06 at 22:22:01
 
Greetings, all.

I have been having a minor problem with my SE84C since I got it.  It just seems the tubes don't set properly, so one of the channels frequently cuts out or produces static.

Some of you may recall my previous post on a similar topic... well, this isn't that problem.  I have checked all of the connections, and I have reseated all of the tubes.  Still, sometimes one of the channels - usually the right channel - cuts out or produces static.

Is there anything I can do to make the connection more solid, so that I don't have these skips or static?

Thanks.

Are you sure the tubes are OK?

No.  I inquired in an earlier post about how to tell when to change the tubes.  Might this be one way you know to change the tubes?  ???

tubes for the C are relatively cheap...not an expensive venture. But I did have a similar problem with my C and turned out Decware replaced a bad cap for me

I too have the same problem. It does not have static though. Sometimes the right channel goes off and I have to shut the amp. When I do that, the right channel gives a 'thud' sound. After that I restart and it plays ok. It happens sometimes, but has been there now for about 6 months. Have to open it up and check the tube sockets. I think they could be the cause.

I just had a fairly new tube give up.  It had a little static and then the right channel went out.   Embarrassed
Thought something melted down at first, but now is 100% with a new tube.

Funny thing is, mine has been working fine for a couple days now.  Maybe I'll try some new tubes, or open it up and check the connections, if it happens again.

In addition to checking output tubes, there could be a problem with the input tube.  They're dual triodes, so one side can go out.  After flipping the bias switch on the fly (I know, I know), I lost one side and the input tube was the culprit.

Welcome to the forum DJ. I have flipped that switch only a couple times while hot.  I got a thud in the speakers is all.  I won't do it again.
