My CT se has been my worship group amp for several years. I have been having an issue with it dropping volume.
If I turn it off and back on it goes back to normal. Sometimes it won't happen again for weeks.
I bought the amp brand new and have never had any issues before now.
Also, I haven't ever had any service done to it either.
Ideas?

There's not a lot you can do to an amp like a Cyber Twin. Since it is basically a computer, can you do a factory reset? Fender SS amps have often had issues with cracked solder joints. You might want to take a look at those.
If I recall, the CT has a tube pre-amp. Maybe check those tubes? And check that guitar input jack...
Sorry, that's about all I've got.

I'd hit all the input jacks (including effects loop) with some Deoxit. Certain jacks are prone to that and the symptom is dropping volume. Happens more in humid environments.

It is definitely humid here. I will hit the jacks with deoxit.
Would a pre-amp tube being loose cause this problem? I took the amp home and played it for hours yesterday after church(we are doing online only services) and I took the tubes out and checked them then reinstalled prior to playing. It never dropped the volume once.
Also, our church's electrical system is ancient and they have us running three amps off of the same power strips. Bass, acoustic and me. Plus 2 effects processors.
Thoughts?

It may be that's all it needed, ie the tubes reseating; just taking them out and refitting can help to re-establish good contact between the tube pin and socket female. Over time, the surface of the metal can develop an oxide layer, which gets scraped off by the reseating action. |

I ran into this on my 1991 Fender Ultimate Chorus. It suddenly lost sound. I spayed each 1/4" Jack with DeOxit 5 and then quickly inserted and removed a 1/4" instrument cable plug several times then moved the next one. I have been 3 years now with zero problem. |
