I have a Rivera Venus 3 that I keep at church. A couple weeks ago, it made some loud static noises and then lost all signal. I shut it down and then powered it back up and noise again, no signal passing. I quick ran home and grabbed my Two Rock EXO, plugged it into the same cab with the same power cable and with the same pedal board etc. It ran great for the entire morning service.
I took the Rivera home to troubleshoot. Fired it up and it played fine. Played for a few hours, all fine. I thought maybe preamp tubes so, new 12AX7s all around and played again all the rest of the week. Took it back to church Thursday night and I fired it up, noise and very low signal. So CRAP!!! I grabbed my little Crate PowerBlock and finished rehearsal. Took the Rivera back home and guess what???? Yep, it plays just fine.
So....before I throw new power tubes in there (I bought a matched quad and used 2 and biased), Is there anything else I should check?
To summarize:
Church has a Port City 112 OS with a 16 ohm Celestion G12H30.
Home has a StageCraft Elite 212 with a 16 ohm Celestion G12H30 and a Eminence Cannabis Rex, also 16 ohm wired at 8 ohm.
I mention that in case it could be transformer related.
Any thoughts? Should I just swap the Power Tubes and take it back to church?
