Title: Ampeg Gemini 1 OT identification
Post by: ndross475 on July 07, 2022, 01:41:47 pm

any of you know if there is any chance this is the original OT?? its an older 64 or 65 Gemini 1 / octal pre-amp tubes.  Picked this up sick but functioning... appears mostly original. Some newer electrolytics and perhaps the OT.

 Looks like a replacement . You can see where the leads are spliced together for starters .

Thordarson was a popular generic replacement transformer in the '60s. Good quality.
