Any Traynor YBA-3A owners out there?

    Just got the amp today and was wondering on where the amp gets loud on yours. I'm used to a 3-4 on a 1-10 type dial, being loud. This amp ,although very clean, doesn't start happening until around 8-9 on the dial. I'm talking a moderate volume not earsplittin'. Enough to keep up with a drummer & guitar player. Think Blues & Classic Rock

    The tubes seem to be ok but I need some other owners input.

    This is the SUPER Custom Special version.

    What speakers are you using? Are you running it at 8 or 4 ohms?

    Also, if you don't know when was the last time it was gone over by a tech, I'd take it to someone to check out if you're not comfortable to do it yourself. Those heads are wicked loud when in working condition. You should check out the new YBA 200, the new millenium version of this head.
     
  3. Get it checked out. That amp ought to be near SVT loud. Something's wrong somewhere.

    Replace the 4 x 6L6 power tubes, and you'll see a huge difference. I did.

    Cheers,

    I think I have the older version. One volume and spark plug tube wires. I think it's a 6kg6? Someone else told me that the volume on this amp doesn't start to really happen until later in the dial
     
  7. I've played a Super Custom Special. It's supposed to be LOUD starting at 11 o'clock. It's a 240 watt tube amp. You shouldn't be having any problems. The YBA-3A is high powered and uses four 6KG6 tubes, not to be confused with the more common YBA-3 which uses four 6CA7/EL34 for 130 watts. There are also versions that use four 6L6GC/7027s for 100 watts. The problem could be as simple as a dirty pot. You obviously have a concern or you wouldn't have posted about it. Get it checked out.
     
  8. I would love th find a "3A" but I would imagine that those 6KG6's would be pretty hard to find. Are they a transmitter tube type?
     
  9. Actually 6KG6's are some of the few tubes where new production is better than most of the NOS examples you'll find, and they're cheap. They're a sweep tube that was used in old televisions. They're also called EL509's.

    i know this is many years late but i saw the post about the yba3a.i was a professional bass player decades ago/i used a yba3a head and 2 yc810 cabs.what an amp.seems like mine was really loud on about 5.we were a very loud band.i used a fender precision and a rickenbacker 4001.i always got great comments from people about the sound.i traded it in for an acoustic 370 head and 2 301 cabs after owning it for years.what a mistake.the traynor was a great amp.i later dumped the acoustic and got 2 yc819 cabs like i had and found a marshall 200 watt guitar head which i used for quite a while.the yba3a and 2 yc810 cabs in good working order is a great setup.

    Here some pics taken at the September 1969 Rock & Roll Festival in Toronto that featured John Lennon and The Plastic Ono Band. Chuck Berry was one of the opening acts. You can see the YBA-3A's in the backline each sitting on two YC810 cabs. Note the unique cabinet of the YBA-3A that never went into production.

    Thanks.I have never seen that cab style on the head.I bought mine new in 1971 i think.I think they had just come out.i was using the yba3 head with my 2 yc810 cabs but it wasn't cutting it.that head sounded good with one cab.i tried using a series speaker cable setup to change the load and it helped some but when i tried the 3a head that was it.I love the amps with multiple smaller speakers.i had a couple of silvertones from sears in the early days.had one with 6 10" speakers that would blow away a bassman.also had one that had 6 12" speakers that was really great.they only made those a short time.Yep,the good old days.

    Thornton, 1969 was the year I got married. Didn’t get here till October 1973. :D

    Edit to add: That stage looks familiar. Where was this event held?

    Paul, it was held at Varsity Stadium in Sept 1969. Back then concerts were usually held at Maple Leaf Gardens or the old CNE grounds. Occasionally promoters would hold them at High Park or Varsity depending on ticket sales.
