Tube amp mod question

    Just wondering if it is possible to have a amp modded to have a transformer balanced line out installed? I have a Traynor YBA200-2 which only has a pre or post EQ line out. Is this something that a amp builder or tech can do? Would love some feedback from some of the pros here. I attached the service manual with the amp schematics.

    Anything is possible. Just need the dough. Isn't that what the Ampeg pf50/20t's do?
    Maybe switch, or mic the cab?

    Yeah the PF20 and 50Ts have the option to do either pre amp or transformer out. Thats where I got the idea from actually. I have no problem micing the cab but in some situations it would be easier to just go DI and it would be nice to have the option.

    But if money no object? A cool project for sure

    The are several DIs on the market that can do exactly that. As in handle a speaker level input. That would be the most cost effective, fastest, and simple way to do it.

    Yes, it's not only possible but it's actually done (more in the guitar world, but it's also done in the bass world). The easiest way is with a passive DI that has a speaker level input, Note that you still must provide a load to a tube amp.

    Thanks guys. I totally forgot about DI box's with speaker level input.... I remember reading up on them a couple years back and it slipped my mind completely haha. That makes things much easier
     
  9. Countryman allows speaker level.

    The Radial JDX is specifically made to sit between the amp and the cab. Sounds great to boot.

    The Klark DN100 will take speaker level also.

    I'd get a Whirlwind Director. The amp takes over the DI line anyway, and the Director also doubles as a good passive DI with a decent little output transformer in a pinch. Cheap and built like a rock, too. I have a Countryman, but if I had it to do over again, I'd totally get the Director. I'd already have one but I don't really need it. DI's I got out the wazoo.
     
  12. The YBA200 is a great piece of gear. If I owned one I'd much rather mod it with a DI out or have it done, than switch to a PF-50 which is just about the same price new.

    Not a hard mod at all as you'd just be running a line trans /xlr /ground switch off whatever output source ya choose. Depending on the transformer you use probably looking at 2-300 to have a confidant tech do the work.
    Down sides would be obviously the cost over buying a cheaper di but also you're drilling holes in vintage gear fwiw.

    Sonically, IMO, not a great difference between the two, it’s not gonna be night and day. Why bother?

    I really just want it for live gigs when I going DI and don't have the option to mic the cab. If I'm using a full tube amp why not get the full tube sound?

    Looks like I can get a good deal on one of those Jimmy. Just run the speaker out to the input and the output to the cab on amp mode? This is the model
