    I picked up a YBA-1A today for $400.:rotflmao
    Have a look, it has a few issues but I'll have those taken care of in no time flat. Guess what I'll be doing all night...:JAM

    Issues are:
    Power cord :eek:
    Bias pot, OK but I'll do a nicer job
    Missing pilot lamp jewel. No idea where I'll find that assembly :dunno
    Missing the panel off the back, guess I'll have to make one, it would be awesome if someone could give me the dimensions for this.
    Going to check all the caps and there are some suspect solder joints and then give it a once over from top to bottom.

    I've heard good things about this amp. Tone report?

    I'm still on a hunt for the YBA-1. I've come across a couple of 1A's, but I prefer the 50w YBA-1. They're both great amps though. Check out the Velvet Black website, if you haven't already, for great Traynor resources ... http://www.informatik.uni-bremen.de/~dace/vb/

    Well the pilot light shouldn't prove too difficult to replace.
    As long as you don't expect to find the OEM Traynor one.
    Just get a generic 120v pilot light jewel type.

    Yeah, that power cord has to go!

    It would also be wise to replace all the electrolytic caps.

    Does it work as it is now?

    How does it sound?

    Sweet :AOK
    Traynor YBAs are excellent sounding amps. Congrats on a great find.
    Cheers,
    Mike

    I've a '68 1-A with a humungous output tranny .

    Kicks like an angry Rhinocerous .

    .. always wanted to hear the 70's version w/ the [relatively] smaller OPT.

    Yes it does work now, I took a brief look at the electrolytics yesterday but today I will test them thoroughly with my Sencore LC102 looking at value, ESR and leakage, I have no intention of fixing what isn't broken.

    Welcome to the forum, Don. Any relation to Jerry Doucette?

    Those old Traynors rock!

    Thanks!
    I've never done any research but I doubt there is any relation.:)

    I've been trying to find out what the back panel looked like on this amp, I've seen three now;

    A small strip across the middle
    Panel in an H shape
    And one big panel that has a metal vent grate in the lower section.

    I guess my first step to to accurately date this amplifier, The previous owner sold it as a 1974 but I have no other confirmation of this information.

    Edit: Just checked the serial number and this amp indeed is a 1974, anybody have any photos of the correct back panel??
