Peavey VIP 1 voltage change

[Dancla0114]

Hi guys,

Sorry about my first contribution to the forum being a question.
But I've been googling and reading for days and I am stuck.

I've received the schematics for this unit from Peavey and I need to change the voltage from 110 to 230V

I know that 2 120VAC jumpers need to be removed and the 230VAC put in place.
I just don't know what else needs to be done.

I've looked at the parts list for both 120VAC and 230VAC and they are identical. (except for the jumpers)

When I emailed Peavey they replied that more needs to be done than just the jumpers. And that's all they said.

Could someone with knowledge have a look at the schematic and advise if they can see something else?

TIA

I sure don't see anything other than the jumpers, but the schematic is very busy because it has the other components for various builds (20W/40W/100W) so maybe that's what the email was confused about.

[Dancla0114]

Yes the schematic actually covers the VIP1, 2 and 3.

Thanks for the reply. I'll give it a day or 2 to get a consensus. I dont want to blow up my daughters amp

The only other thing I can think of is that the fuse for 230V is usually half the current rating of 120V version fuse.

That's what I would have thought too.

But the board is obviously a shared board.
i.e. it is the same board for both voltages.

And it clearly states 3.15 250v

And the parts spec for both specifies 3.15

That's one of the reasons I wonder if I'm missing something.

I couldn't find the fuse listed in the parts lists?

[Dancla0114]

No you're correct.
I'd just been going through that again.

Looked at it 5 times thinking "I know I've seen it"

The only places it is listed is on the schematic.
And on the board itself.

Hmmm.

I wonder if there would be anything about the fuse in the owners manual or specifications.

[Dancla0114]

I'll have to have another look.
But I never recall seeing it.

One thing that has me worried is that in a previous life I remember that USA use Line to Line for voltage, and Australia uses line to ground.
And that used to throw fuses levels

[Dancla0114]

Ok, so i pulled out the 2x 120VAC jumpers and soldered in the 230VAC.

Hit a refresh here to see if there were any new posts. Which there weren't, and I thought "I'm going for it"
So I put the board back in and kept it disconnected from the other boards and powered it up.

Nothing.

Turned it all off and connected everything.

Bingo! Running perfectly.

BUT, I'd still like anyone to throw thoughts regarding the fuse. I'd hate for a fault to get through.

Hopefully this helps someone else in the future.

Sometimes the "other stuff" is not so technical. To make it legal, you would technically have to replace some of the labelling on the panels to reflect the new power needs and the new power draw. You probably don;t care about that, but the OEM does.

All I see is the jumpers, so you are probably where you want to be.

You probably needed a different power cord, I'd wager.

Thanks Enzo. Yes that might be it. I hadn't thought of that.

Yes I had another cord with an earth.
I've also got a USA adapter somewhere so I still could have used the original.
