ive seen the original tiny terror schem. ive not seen the TH30 one. I wondered if the Dark Terror might have been along the same lines as the Phaez Daisycutter. Using a cathodyne PI to free up a preamp triode to be used to add gain. Older bigger oranges had cathodynes, so i thought it might be possible. I wonder how well the loop works. I thought a lot of the gain tone came from the EL84's getting pushed, at least in the original tiny terror. So a loop before the output stage might not be ideal, depending on what someone is using the amp for. Can't really add a loop after the output though. I know the gain and loop were added according to customer request. The transformers might be cheap but they should be ok. I know the head Tech at orange pays attention to what goes into those amps, it's not just some bean counter.
I wouldn't be surprised if the output transformer from a Dark Terror is the same size as a Mesa Single Recto OT.
