Electrovibe capacitors

[tonycombs]

Did I make a BIG mistake by putting in 16 volt caps in my Electrovibe?

 

[Nostradoomus]

you sure did!

I'm stocking up on parts for this build. Going with Nichicon and Panasonic
50V electrolytics.

I thank you for your reply…guess I need to pull and replace them. I’m kinda new to the process and ordered the parts quite a while ago…I appreciate you helping me in this learning process…

After a while you start to get a feel for what is safe from premature failure and letting out the magic smoke.

Technically you should be good with leaving all the caps in the phaser section at 16v.

Power supply caps PRE charge pump should be good at 16v but anything POST charge pump should be rated at least 25v, with 35v preferred.

You have to think about what voltages are “hitting” those caps directly.

For the phaser stages, you might have 12v at the bias resistors of the darlingtons but those caps in the phaser stream are not getting that much voltage and 16v should be fine.

In reality, the only caps you should have to change are those “seeing” 18v directly.

That is good news…I will get on that…many thanks. My Semi Sweet Distortion went so well, I was bound to hit a snag sometime…

I can see why you are a Well Known Member…being more of a musician than a technician, and being more comfortable reading a score than a schematic, am I correct that the Caps in question are C 11, 19, 27, and maybe 22? Thank you again Big Monk
