Traynor YBA200-2 problem (again)
Last October (2012) my YBA200-2 blew up (something got fried and the power tubes started drawing maximum power, nearly caught on fire, never got a decent explanation from traynor or the local tech, but it got repaired under warranty)
Now, for the last 2 week, each time I take it off standby, it "crackle" and "pop" for 2 to 10 seconds loudly. After the cracking sounds stops, everything seems to work fine (I think its not as loud as it used to be, but i'm not sure). I can take it on and off standby without a problem. The crackling sounds will only come back if I power it off for a little while.
While it produce the cracking sounds, the power tubes will glow blue-er than usual and return to their normal appearance as soon as the sounds stops.
I don't think i'm being too hard on my amp. I practice once a week at reasonable volume, I gig once a month (on average), Usual volume is never higher than 5, the only thing i'm maxing out is the gain, it is usually set at 9 or 10.
At glance, nothing appear to be broken, loose, burnt or bent. I have good technical skills, but i'm not familiar with the inner working of tube amps, and I don't have the right tools to test anything.
I'm taking it tomorrow to the local L&M, the local tech is a good guy, but is technical explanation are something quite dodgy and weird. Knowing him he will probably try to change the tube before bothering to check anything else. If that doesn't work and its still under warranty (it is) he will probably just ship it to traynor (I think its in Ontario, i'm in Quebec, so its not a short trip).
I have a big show this week and losing my amp for a another month-long trip to Traynor would really piss me off (for the second time in less than a year).
Have I bough a lemon or are tube (or traynor) amps so fragile it is normal for them to break every year or so?
Has anyone ever had similar problems?
I take it you're in Canada..?...A reputable tech in my area was telling me he was having many issues with a customers YBA-200..If I were you,I would repair it,and sell/trade it....My motto with any amp is fool me once ,fool me twice....see ya!
Yep, i'm in Canada
After unplugging it and letting it cool down for a while, I tried verifying if there wasn't just a tube that was knocked off, or improperly inserted in its socket. Eveything seemed fine, all tube we're properly in place.
When I turned the amp back on, the problem was worse. The crackling would not stop and the power tube started glowing way brighter than what they are suppose to. Almost exactly like the problem I had 10 months ago.
I bought the amp brand new in july last year.
I'm getting it repaired and than i'm getting rid of it. Probably not gonna buy another traynor.
Should be an EASY fix.
Many many people have these amps with NO probs whatsoever. I had one & not ONE problem it was a superb amp for me. I'd not hesitate to get another. I've used all tube amps all my playing life- since 'C'74
I'm sure a decent tech would be able to fix this easily. Hopefully some of those in the know here on TB will chime in.
ps. I also owned a YBA300- another superb amp from TRAYNOR- who's rep is very good as is their customer service.
If you bought it from L&M, then they should provide you with a loaner while yours is being repaired under warranty... I would insist!
I have nothing to say against L&M or Traynor about their customer service, thing always went smoothly. But I won't be kepping an amp that break down with the same problem every year.
I can completely understand your position. It may well be this brand and you might not be a good match (who knows why that can happen). But for understanding sake a mechanical connection can work but become intermittent. A failing soldering station (iron) or a Monday hangover can miss the soldering of that connection that makes it a solid electrical connection. If the mechanical wrap of that connection was improper before soldering the solder will hide it and since solder is NOT a good mechanical connection the connection can fail.
They are built by people :D
Techs can well assume if it made it out of QC at the plant that everything is A-OK. Only after a repeat failure will they look deeper.
IMHO give the repair another try if you like the sound of the amp before giving up. It is your choice of course. ;)
It sucks about your amp though. I've heard nothing but good things about that amp and have played through one on occasion. Let them have another look and hopefully they can figure out the issue.
Yeah, maybe this time the repair could be good and last until the end of time. But, if it does break again next year it won't be under warranty anymore, and I find it completely appalling to buy an extended warranty "just in case" the repair wasn't done properly for the second time...
Anyway, Its in the hands of L&M (and Traynor). The L&M manager told me about a "lemon-protection policy", if the same component break too many time, the entire amp can be changed. I told him I would like that.
If its entirely another problem (with similar symptoms) maybe i'll keep it. Maybe. I really like the tone of this amps, but I need something reliable...
I would actually be pleased with a replacement unit. Or just an in-store credit of the amp value...
My local L&M doesn't have anything in stock that would be considered a suitable replacement (IHMO), but I have a good backup amp, so that not really an issue.
I got my head back today. Had to pay 270$ worth of tube (since they are not covered by the warranty).
It seem one of the power tube died and the 3 other power tubes where in pretty bad shape (these tubes weren't even 10 month old. They were installed by Traynor, during my last repair, in November 2012) and caused all my problem.
According to the L&M tech.
I asked him what would could have caused the power tube failure. He just answered something like "tube are not what they used to be, you just has some bad luck, it can happen". Apparently the rest of my amp what in perfect condition, I had nothing to worry about, I was extensively tested in-store.
I bring back the thing home, plug it into my cab, I took only 1 hour for the problem to come back. Everytime I take off stand-by, it will "hiss" and "pop" and stabilize after 10 to 20 seconds. During the noise, one of the power tube will spark and glow weirdly (compared to the other 3 tubes)
Right now, i'm pretty pissed. I know Traynor are supposed to be reliable amps, but my unit just isn't.
I'm gonna have to haul the damn thing to L&M again monday, because they are the only traynor licensed repair shop around here...
Could the problem be a mismatch of ohms? Maybe a speaker in your cab is shot and putting a different load on the amp. Causing the tubes to overwork and fail.
I had a situation like this with my old Mesa 400+ blowing power tubes. It turned out to be the fault of the cab.
I doubt it, I used an entirely different cab (and cable) today. (Bought it this week while the amp was still in the repair shop)
