API compressor and GTR pedals

If you'd like to build a project with a transformer, check out this thread:


The list in the thread probably needs updating.



As for the API, I'd be more interested in the LLX Bass pedal, but alas, it and the two guitar pedals (CMP and GTR) use a:
"Signature API output transformer", which I don't think API sells separately.

The bass also utilises a "Proprietary API 2510 OpAmp".


Could it be cloned to "close enough" specs? 🤷‍♂️
 
The tranzformer pedals are very interesting projects. They don't contain many parts, but the transformers and the discrete opa are a little bit expensive. But real worth to built, because out of production.

I have a pair of these new ones. I've been meaning to take them apart and poke around.

At +18v they have a ton of headroom and sound really open.
I didn't find running them at +9 and clipping the opamp to sound very nice.
