I killed a Sozo with one slip of the iron...

[Blindog]

So I was adding a variable slope and switching out a silver mica cap for a ceramic disc in my Plexi style build. I plugged her up to check the results, and noticed I had a ratty, fart filled distortion with the amp on about 5-6 (bright channel). I started checking voltages and noticed the cathode follower voltages were low after the 100k, and I had 0 volts on the .68uf/820 to ground. That's when I saw the damaged cap. I was surprised because I've knicked some Mallory 150's before and they survived...but it does seem the outer tube is bit thinner than those caps, at least on a .68uf. Lesson learned!

Ack! It happens. Easy to do too.

[Blindog]

Yep, $4 down the drain...at least .68 Sozo's aren't so pricy. I ordered a couple more, the whole amp has them so I must feed my OCD

I've had that happen multiple times with Sozos way back and never actually had one fail on me. I'm surprised because the damage on yours really doesn't seem that extensive.

I've done that to a Mallory cap. Terrible sound

It's the kind of thing you only do once in life - I changed my layouts for more space between parts and it's not happened since

[Structo]

Yep, I've melted Mallory 150's before.
Usually I pull it as soon as I notice the damage.

When soldering in tight spaces, I often clamp in one-or-more forceps to act as a shield and heat-sink for adjacent delicate parts/wires.

you're not alone, I did that to a mallory 150

I know right? I was surprised as well...it measured "0" on my cap meter out of circuit. Just my luck I guess
