It sure looks like it. The primary and secondary impedance are the same and the resistance is pretty darn close so you should be fine.
That's what I am thinking but the fact that the transformer is just used as a inductor is what is making me dought that :/ the build docs said it requires a 500mH inductor and I believe that audio transformers can act as one but I got no clue how they work or how to know what value the 42tl013 as got ... Like you said primary and secondary are the same but I think that the 42tl as got a lower power rating, so does that it's inductor factor xD I don't even know what a inductor does !!!! I believe it's googleling time !!!
Just got my new mega328 transistor tester and used it to mesure the inductance of the 42tm003 transformer ... I get 2.5U xD about 5 times the inductance of the 42tm013. I dunno if I can trust the tester's reading without comparing it to a 013 :/ I have a electronic store in Montreal that sells the 013 but it's in traffic heavy place and is closed on the weekend so I might not be able to get a hold of one soon ! Maybe in a week or two.
Looking at the stats of the 003 vs 013 I did notice that the 003 is 4-5 time heavier than the 013 even if they have similar impedance and all, so I would be wait before buying a 003 :/

I still have my boards unpopulated at the moment :/ I got a few other builds I need to finish before I get to it! I have a few different transformers on hand and I am planing to socket and test different ones to see what I like best
I will be updating my findings in a couple of weeks 
Quick update.
I got the transformer from the electronic store here in Montreal... Didn't realize it was a 42tl013 and not a 42tm013 :/ I picked one up regardless and I believe be close enough to work. On my transistor tester it reads 641mh Just checked mouser.... It's also out of stock

641mH is plenty close. The resistance is low enough. Go for it!

Just plain old inductors (as opposed to a transformer). I used these: https://www.digikey.com/product-detail/en/bourns-inc/RLB0913-104K/RLB0913-104K-ND/6677257
They're only 100mH, hence having to use five of them. The up side is that they're $0.68 a pop, so you get the inductance you need for less than 4 bucks.
So I finally tried that 42tl013 at 640mh.... I just get a muffed low volume signal and the 2 other foot switch don't work :/. I will double-check all the resistors and connection, if I don't find a culprit I will try and remove the transformer and just jumper the connection see if it work... I got a little bit too cocky and soldered it without testing it first xD

Can you recommend using 5 small 100mH inductor in series? Or is there any other good place to order a fitting inductor from germany. Shipping costs a fortune when ordering from mouser. I would really love to get something from tayda but I can't find anything close there.

Also which holes of the pcb should be used when having 5 small 100mH inductor in series? I can't really tell from the picture

If you have the patience and can get you hands on an MPP toroid core you can wind your own. Been there, done that. Helps to have an inductance meter in case you loose count of the turns. The Cheap Chinese Transistor Tester will suffice for that. If anyone is serious about doing this, I can provide winding instructions.
