Title: Things I can do with the transformers TY-250P
Post by: Elijah-Baley on October 22, 2023, 06:10:26 AM
I'm trying to build a reamp for a friend using this TY-250P transformer. We are discussing about it here: https://www.diystompboxes.com/smfforum/index.php?topic=131253.0

I'm not sure it will be totally fine. So, in case I would like to re-use it... what I can do with it?
AMZ Pickup Simulator, DI Box... Any ideas?

Here's the datasheet:

Thank you.

Thanks. I found it.
I'm not sure about it, but it could be an idea. I should design a veroboard layout by myself.

I'm a bit confused about the pin distance of this transformer. Does it fit with the stripboard?

The TM79 uses the same transformers to create analogue clipping. Check it out.

Yes, I know it, too. :)
Too bad I need two transformers, and I'm going to buy just one.
Thank you.

There's no much, with this transformer, I guess.

It is so true! ;D

I decided to buy the TY-250P and try the reamp, so... we'll see what happen.

I started this thread over one years ago:

Quote from: Elijah-Baley on April 19, 2022, 11:39:14 AMit has the Focus Switch, it's the push-pull Tone pot: «[it] activates a passive boost that darkens highs while increasing bass and mids for an effect like overwound pickups.»

I'm searching some schematic, but I'm not sure I found something verified.
One I found doesn't correspond with the thing I'm saying now, but... it could be a coil in series with the pickups that push the signal like a bigger pickup?

Do you think I can do it with with the TY-250? In that thread there's nothing sure about the schematic and I can't understand what exactly transformer it is.
