Ugh - Preamp just screwed up

[lreese]

All of a sudden I lost output A on ye old Triaxis.  Output B is A-OK.  Worked like a champ for 15 months.

Its not the tubes - swapped those out.  

So now its heading to the shop tomorrow AM - I'll be in the area with the Mesa authorized repair place.  I'm also dropping my pre-500 Recto there to have the relays looked at.  I'd attempt it myself, but i really don't want to mess with the PCB.  Lets pay out and get it done right.

My guess is a bad pot or cold solder joint.

Hopefully the damage won't be too bad.

So the next 5 or 6 days looks like its either a Fuchs ODS pre or Mark IV pre.  Who knows I mike like them better, its just a pain.  Or I could slave my plexi into the current rig - I like easy.

At the very least, it will get baked!

Lets see how baked my wallet gets - I'm betting the recto will be stiff ()

Can't be much wrong with the Triaxis. I just know it ain't tubes.

The doctor just called after examining the 1st patient...

Blown resistor. I'm going through and have a recalibration done on it today to save on another potential bench charge. Might (Fingers crossed) get it back this afternoon. Otherwise tomorrow morning.

The Dual Rec has not been looked at yet. Its the LDR defect those had I think - gonna cost.

[lreese]

And they are back!

Out $280.  Could be worse.

Sounds a lot like the bill I got when the Fender and the Marshall shit the bed at the same time. At least you are whole again.
