Update - I've managed to get ahold of the Line 6 transformer from the Spider II 15. The outputs are 7VAC for the two red wires (relative to each other), and 15VAC for each of the two blue wires (relative to black). Transformer and plug is identical to the one used in Spider III, probably just a different supplier. Just thought I'd update this post for reference purposes.  Thanks again for the help guys - the amp is up and running again.

Thanks guys. I will check it out and see what I can find out.

Happy new year all.

I am trying to find a replacement transformer for a Line 6 Spider III (3) 15w amp. In my search I think I've located a transformer from an older model (Spider II) of the same wattage.  The part number is different and I have no information on the outputs. I don't have the transformer on hand, I only have a pic of it. The transformer is stamped:
611-11300015-1G
T57-0413005-12

Would anyone know what the outputs are for this transformer?  There are 5 leads red red blue black blue.

Thanks

Thanks again for the advice, JM.

Thanks JM.  I think I might have to consider the option of using a step-up transformer after all  (unless I happen to come across a surplus OEM transformer).  It will most likely work out to be cheaper anyway.  Do you think there might be any issues with additional noise being introduced by the step-up?

BTW that other thread was most helpful - that's where I had gathered most of the info regarding the needed OEM transformer. 

Here are some pics of the guts (with the power connector disconnected from the board in two of the pics). Thanks

Thanks all for the info.

JM - I'm a bit new to the world of transformer selection, so please bear with me.  I'm assuming that I will be needing a center tapped secondary (30-32VCT), to provide the 2x 15.2VAC the OEM transformer provides?  I have had no luck finding a schematic for this amp, so I am not sure if the center tap is used.  I'm assuming it is - the five outputs all go to a single 5-position plug (very much similar to a pic in this post).

I'm also not sure what to do about the other isolated secondary (7VAC, if I interpreted it correctly) - probably slim chance I'll find a non-OEM replacement transformer with those exact outputs.  Or do I need to consider hooking up two separate transformers (one around 30-32VCT, and one 7VAC)?

Hello all,

I found the board while researching how to convert a Line6 amp from 220-240v to 120V.  The amp, a Line 6 Spider III 15 watt model, was purchased outside the country.  I don't really want to go with an external transformer.

While researching the site I came across this thread where I gleaned a lot of good information (thanks Phatt, J M Fahey, zappacat, and others) on a related topic.

The transformer in the overseas model of this amp (if that's the proper term) is On-Tech 2X-5730-04H0.  Information from the aforementioned thread indicates the US-model uses p/n 1X-5730-04H0.  While I can't get to the On-Tech webpage (not reachable), the voltage info posted earlier by J M Fahey  for the 1X-5730-04H0 is: I/P:100/120VAC 50/60Hz O/P:15.2VAC x 2/7. 

A quick AC voltage measurement of the transformer outputs on the 2X-5730-04H0 (disconnected from the board) is approximately half of the spec voltage (don't have the notes with me), which makes sense.

My plan is to swap the appropriate transformer (if I can find one), and install the appropriate T1AL fuse.  I think that all that's involved, unless I'm missing something?   Had already checked with a Line6 repair center and it would cost nearly as much as the amp itself to have them do it.  So I'm hoping someone might have a spare transformer, or something.

Thanks!

(I have posted a WTB in the swap forum, btw)
