Hi everybody, I have the opportunity to buy a 1969 Ampeg SBT SS preamp for a really good . I have a a traynor YBA200 that I use as my main rig and I wasn’t sure if I could connect the SBT to the YBA. I know the amp has a Pre Amp out and Amp In spot but I’m not sure how it would work. If anybody could give some insight that would be great !
