While listening to my system my Rhea blew up



I was preparing to put a record on the TT (system was on for approx 35 min already) and spark/pop/smoke came form the Rhea. I shut everything off and after a few minutes tried to see where the smoke came from. I could not detect if it was from a tube blowing up (a real spark!!) or from a cap etc???

I will ultimately need to return it to my dealer but was curious (Jim White are you around?) as to what it might be.

I experienced the same event once. It was a capacitor and sounded like a firecracker going off.

Aesthetix can be tough to get hold of -last I looked they didn't have their own web site - but don't be alarmed. You may need to go through the distributor, but in the end Jiim is a great customer service guy. Based on my experience with him (bad tubes in an early production Rhea) I'm sure he'll get you back up quickly and walk you through what happened.

Sorry Rick!This type of experience we all go through,from time to time.It sucks,but if we have good representation,the problem usually has a happy ending.

Best.
Film dielectric breakdown, possibly from over voltage condition, high peak current or over temperature. When a cap breaks down, hydrogen is generated inside. PC mounted caps have "vents" (grooves) in their tops that are supposed to let this pressure release before the rubber bung on the bottom blows out. Sometimes that doesn't work out. Many axial lead(as used for point-to-point wired components), and multi-section capacitors are built like a small tin can with a cap crimped into one end. When pressure builds up from electrolytic breakdown in one of those, you often get the firecracker effect. A tube with an internal short can cause a sudden high current condition. Hopefully it's that simple.
Your description is like a tube failing catastophically and taking out something with it.
