    Picked up this Yorkville xm100 last year cheap but never really did anything with it till recently. The thing is it sounds pretty awful and I'm not sure if it is a bad amp or a bad speaker or both. I ran the amp through another 4 ohm speaker and it sounds bad at low levels and gets worse as you turn it up. I hooked the speaker up to my musicmaster and that sounded bad too.

    I didn't see anything obviously wrong in the chassis but then I'm no electronics expert and don't know how to test components. The speaker is a 15" Eminence 7347 4 ohm 200W, 67-0310A 0095 I think that means it was built in 2003. Anyway if they are both bad I was thinking I could get a new 8 ohm speaker and use the combo case as a cab. Is that the best way to get something good out of this?

    I used the speaker out of this Gemini GX-450

    to test the amp out. It turns out that if I run my bass through my little Mackie mixer and into the GX-450 it's a pretty good bass amp. Turn the volumes more than halfway and it is seriously loud. And it doesn't sound crappy. I am actively researching bass amps at the moment but this will get me by for now along with my musicmaster. Feedback?

    Nothing helpful from me, but I hate those Yorkville 15s. Impossible to get anything but flub and mud from them.

    Ha! Flub and mud would have been an improvement over what I heard. But the Eminence speakers now seem to be well spoken of. I'm still leery of 15's and will probably go with a 12 in whatever combo amp I finally get unless I can find a small head.

    You'll find lot's of 15's you'll love, hate and everything in between...speakers have come a long way lately. I have a variety of 15's. 12's and so on...it's all about design, great drivers and a well executed enclosure :)

    Yeah all you can do is read threads and manufacturer specs and claims and hope for the best.:meh:

    Eminence Legend CB158
    Eminence Kappalite 3015
    Eminence Basslite 2515

    Measure the cab and ports and plug it into winISD. All the Eminences are preprogrammed ready to go.

    OK. Here's an update and a happy ending. I was fortunate to find an amp technician on Craigslist. He resoldered all the front panel components, resiliconed the transistors, resoldered two capacitors and replaced the effects return jack which he called the switching jack and the headphone jack. And the amp now sounds GREAT. Very happy with the outcome.

    I think not necessarily. Yorkville/Traynors seem to be well spoken of and the amp is probably more than 10 years old and mayby lived a hard life so while I was initially disappointed with the amp I'm glad the tech could breathe some new life into it.

    I don't know, I always thought Yorkville has gear that is less than reliable. I remember years ago when searching for my first bass rig the saleman pushed Yorkville on me (L&M owns Yorkville/Traynor, they are basically like acoustic at GC). One of the biggest pro's to getting Yorkville is their warranty, you can literally break it yourself and they will cover it. Now some folks might see that as "we stand behind our gear" but I saw it as "Our gear breaks so much we just fix it no questions asked".

    I have experienced a few total lemons with the Yorkville badge from amps to P.A. speakers. I would regard Traynor as more reliable any day of the week.

    Glad you could get it working OP, better to see gear fixed than trashed. I never cared for the tone out of that combo but it did get pretty loud from what I remember.

    cool story! great outcome!

    I have yorkville gear from 25 years ago that still works like new other than dirty pots. yorkville is a fine company.

    I was under the impression that yorkville == traynor - same company, different badge and variations of similar products.

    both owned by l&m so maybe that's my confusion.

    Anyhow... old yorkville stuff is great and I played and toured with a yorkville bass combo 200w amp for years that was flawless, reliable and sounded amazing.

    you should really like this amp now that it's working - they're quite cool, although I haven't used that generation (last one I owned was about 8 years older).

    I can't disagree with you entirely because the tech himself pointed out the disadvantages of the PC board mounted components of the front panel.
