Has anyone tried swapping the Ge OC71 (or similar) for a silicon transistor?
Any pointers on what could work well enough?No reason you couldn’t.

Guess I'll just try my way through a bunch and see what works.I would imagine a PNP device between 70-100 hFE would do.
You could put a pF range cap across base and collector to smooth things out if you feel it needs it.
I would socket it and play around.Guess I'll just try my way through a bunch and see what works.
Yeah that's the plan. Really want to try and play around with the transformer that's in the pedal too.I would socket it and play around.
Yeah, that's what I've read too. Seems like snake oil. They're pretty expensive as well. Neve seems to really swear by transformers though, so maybe that's why it was included in the original design.As far as my understanding goes, that transformer is doing essentially nothing aside from lookin' cool. I've read a few comments scattered around from folks who've built it with the transformer on a switch and can't hear much of a difference with it in and out of the circuit.
True. What I was wondering: Hudson advertises a different transformer in their Broadcast AP model. However, they seem to be identical in impedances and ratio. So I am led to believe that the biggest difference between the two circuits is the use of a silicon transistor instead of the OC71.The transformers in actual transformer-coupled mixing consoles are absolutely doing important things and (can) have a big effect on the sound; those units are also using much larger, higher quality iron running at much higher voltages. But yeah, just putting an audio signal that's already pretty distorted through a teeny 1:1 transformer seems like it isn't going to do much of anything. Maybe some bandpass filtering?
Yes. It feels like it does basically nothing.In any instance I have also heard that the transformer doesn't do much except drive up the price and the hype. I also know someone who is putting out a transformer less all silicon dual version in a 125b for those so inclined to be patient.
very true. when you know how little it takes to build that fuzz you really don't feel like spending the moneyMost of the boutique game is just marketing, guitar gear junkies are so easy to manipulate especially when you have endorsements from players who serve to that niche market.
Ok, you pegged me....and to think I pay big bucks for counseling and we've never gotten to this level of truth.........guitar gear junkies are so easy to manipulate...
I looked in to it a while back and it's the same circuitry as the Broadcast, but with a silicon 2N4033 transistor in place of the Ge transistor, and an OEP Z1643E transformer instead of the TY-141P (both 10K:10K CT transformers).
