Cathode Bypass Caps C106 & C112 - Electrolytic?

[Liquids]

Ampeg V4B

C106 & C112 Cathode Bypass Caps.
They list as 6.8uF and polarized. According to that value I would assume they have to be electrolytic.

The ones on the board are very small black plastic rectangle types.
Certainly don't look electrolytic.

here is an image i found online.
On the far right top corner you can see black caps.
Those are the ones I am talking about.

I ask because I am replacing most of the caps in the amp and especially since they are supposedly electrolytic I wanted to replace while im in there. Unless they aren't worth messing with.

anyone know the scoop on those caps?


Thanks,

Yep.

They're in V4*B* amps circuits only and at that, they're for the ultra-low circuitry. They're cathode caps at a certain value for a low-mid bump, when combined with the other circuitry in the ultra-low.

Do you use the ultra low? I mean, by all means, replace them if you feel the need, because as you said - you'll be in there (and getting at that board IS a bit of a time-suck when you need to get at it for anything).

But that's the scoop.
