TC SCF Chorus Flanger 110v to 220v ?

[tonetony]

I have contacted TC and they don't give support on this subject. They seperate the markets of USA and Europe. Thats why they do not provide a switch on the unit itself. Maybe a little soldering will be required for this modification. I can do it by myself but don't know where to solder

Can I send you the schematics? Does schematics help for this modification?
Many Thanks!

Hey venedikli, could you send the schematics to me as well please?

Thanks man

I was modding my scf, but I did something wrong with the pots, now I dunno what pots to replace with. Could someone send me the schematics please? I love this pedal and i`m soooo frustrated that I actually destroyed the pots.... Argh...

Much appreciated!

Hey pikasoll

I personally cannot remember of receiving an email regarding the schematics. I just checked my inbox and i couldn't find anything. On top of that, i just moved places and my computer is still packed (just in case it is on the hds). But i was never keen on doing the mod anyhow and i personally returned the pedal to the original owner for a refund.

The following information might be useful to any potential TC Chorus/ Flanger buyer: I spoke with TC directly and the case is that they make two different versions of the pedals. One for 240v EU power supply and one for the States. The seller on eBay of the pedal i bought was misled by the information on the website that says that it is for both 120/240 volt but what they most probably mean by stating this in such a stupid manner is that they make versions for both voltage.

That's all folks

Hi folks,

Many years has passed and none of you who has recieved the shematics has reponded to me

Any of you figured out how to convert our chorus pedal to 220v?

I am on this issue again. Please share if you have any information about this subject.

Thanks

You would have to buy the 220V version of the power transformer and have it installed.
Otherwise you could use an external 220V to 120V "travel adapter".
The third option would be to have it modified to run from a DC "wall wart" type supply.

[venedikli]

Is this yellow sticker part is the transformer?

[Jazz P Bass]

That is it.

It's clearly marked: 115V/ 24V

[J M Fahey]

You've already solved it.
That part is the power transformer, it clearly states 115V primary, secondary= 24V 0.8VA which can also be written as: 24V - 30mA .
Search supplier catalogs for it or write TC asking for:
"I want to buy a 230V primary transformer for a TCxxxxx pedal, serial number yyyyyyyy"

Or get a Tech who understands what those specs mean and let him deal with it.
A regular Tech *might* charge same or less, letting him source a proper transformer, than what an original transformer would cost (*if* available).

[venedikli]

24v 30mA will help. TC is going to charge way too much for a regular transformer. I can find a replacement I guess. And maybe I can find one which is universal as 110v/220v to 24v.

I will share the link here so everybody can replace it easly with a soldering iron.



Thank you all.

[J M Fahey]

Fine.
Only slight problem will be to find one small enough to fit in that limited space.

Although, as also suggested above, you may add a hollow plug power jack and use an external , easier to find 24V AC transformer.

[venedikli]

that is something I am trying to avoid. instead of a second external 24v transformer, I will keep using 220/110 converter.

I believe it is possible to find one similar size. I found 0.6 va on ebay but trying to find exact spesification to avoid any possible background noise.

Encapsulated Mains Insulated PCB Power Transformers 230 6 9 12 15 18 24 Vac V AC | eBay

This is a multi listing and he is selling almost every value but not the one I am looking for

If any one can share a link to a similar transformer will be highly appreciated. I have digged for the schematics and brought them up but I need help to find out the right transformer.

Many thanks

TC SCF Chorus Flanger Schematics (very hard to find)

Venedikli - the best option in my opinion is to buy a replacement from TC.
They quite possibly had a custom run made.
I'm sure it would cost less than your stepdown transformer.

It needs to be safely installed -not sure if there is a ground wire or not
but 230v lurking in a metal case on the floor could be an accident waiting to happen.

I had a quick look and via Radio Spares um RS components there is one available
from BLOCK Transformatoren-Elektronik GmbH

BLOCK Transformatoren-Elektronik GmbH :::: Products

a VB 1,0/1/24 which is a 24v/1VA pcb mount transformer but the pins are in the wrong
spot from what I can tell.

The physical size may be an obstacle as well.

A mini PCB drill could assist in fitting the transformer with suitable modification underneath
ie wires from pads to pins.

I don't recognise the logo on yours ..if you could find the original manufacturer there's a chance it
may be a general production run product.

It also could have been custom made so you may have to order 1000 pieces...!

[venedikli]

thank you for your detailed information...

Could you tell me that is 0.2 va gap will make a difference on the system? Will it effect the sound of the unit I mean?

I am going to ask TC for a replacement unit btw. I will write here

"Could you tell me that is 0.2 va gap will make a difference on the system? Will it effect the sound of the unit I mean?"

Not at all.

It just means in your case the transformer is capable of delivering slightly more than required.

In this day and age accountants seem to play a bigger part in design, i.e. the smallest current transformer that will supply
the "goods" without burning out , as it costs less than a slightly bigger one.

Good examples of this are the small plug packs - wall warts that supply answer machines and other domestic items.

They often get hot which means they are running at their maximum output which is why regulations were introduced
to fit a non resettable thermal fuse to stop them catching fire .. which a lot of them did !

With a slightly larger one the "appliance" using the power will only take what it needs leaving head room which means
the transformer can comfortably supply the appliance without any strain.

Another way to look at it is the electricity coming into your house can supply enough to run a stove or a large heater/radiator
but you can just plug in a 15 watt light bulb and it runs quite happily ignoring the huge amount the power outlet is capable of supplying.

Hope this makes sense !

I think it's the wisest move to contact TC or their local service agent for the genuine 230v P.C.B. mounting transformer.
