Guest HRB853370 Posted September 27, 2013 Share Posted September 27, 2013 I plugged my 137 into my Delta Blues 210 tonite, and I had wonderous bluesy tones, for perhaps 15 seconds. Then, it was as if somebody unplugged the amp. The sound garbled and faded out into oblivion and that was it. Turned the amp off, waited a minute, powered it back on, NOTHING! So did I blow a tube? A rectifier? Where should I start? Is there any simple tests I can perform before hauling it off to the amp repair shop? Had this thing for 2.5 years with zero problems.

kbp810 Posted September 27, 2013 Share Posted September 27, 2013 Does the light still come on? If no, then probably just a fuse; if yes, my first suspect would probably be a preamp tube - take a peek and see if all the tube filaments are lighting up. You can try swapping a few around if you have some to borrow from another known working amp Link to comment Share on other sites More sharing options...

Guest HRB853370 Posted September 27, 2013 Share Posted September 27, 2013 Tube The preamp tubes are 12ax7. Are these relatively inexpensive through a vendor such as Tube Depot? Link to comment Share on other sites More sharing options...
Guest HRB853370 Posted September 27, 2013 Share Posted September 27, 2013 OK NONE OF THE TUBES LIGHT UP, EITHER THE PREAMP OR THE POWER TUBES. NOT GOOD. Link to comment Share on other sites More sharing options...
kbp810 Posted September 27, 2013 Share Posted September 27, 2013 You might have a second small fuse for the filament/heater; sounds like that fuse has blown Link to comment Share on other sites More sharing options...
kbp810 Posted September 27, 2013 Share Posted September 27, 2013 I was just looking at a schematic along with a few pictures; it looks like there is indeed a second fuse for the heater lines, but that fuse is located inside the chassis. That fuse would be my top suspect Link to comment Share on other sites More sharing options...
bolero Posted September 27, 2013 Share Posted September 27, 2013 IMO take it to a repair guy I'm no expert, but if the fuse blew, it blew for a reason...could be a tube died, but it's probably a good idea to get the bias checked anyway, if you are replacing a tube? preamp tubes usually last for years Link to comment Share on other sites More sharing options...

kbp810 Posted September 27, 2013 Share Posted September 27, 2013 AXE-FX/ End of Story... While the Axe FX is certainly cool, I fail to see how this helps Slammer repair his Delta Blues... unless you are saying that on top of amp/speaker simulations the Axe FX can also repair tube amps; in which case, I would provide a stern warning that this is probably the sort of thing that creates skynets, terminators, and the matrix as well. So at this time, for the benefit of humankind, I think I would advise maybe trying to replace the $0.50 fuse on the delta first. IMO take it to a repair guy I'm no expert, but if the fuse blew, it blew for a reason...could be a tube died, but it's probably a good idea to get the bias checked anyway, if you are replacing a tube? preamp tubes usually last for years It is certainly plausible that it may have failed due to a mechanical failure as opposed to a high current draw condition after years of being subjected to speaker vibrations; but in either case, unless you feel 100% comfortable in opening up the chassis to take a peek and/or replace (and know how to do so safely... i.e. discharge the caps and check for any remaining residual charge), the above is good advice. Might as well just take it to a tech and let it get a full "check up" while its there. Link to comment Share on other sites More sharing options...

rockabilly69 Posted September 27, 2013 Share Posted September 27, 2013 Open the thing up, keep one hand in your pocket, and replace the fuse. If it blows again, take it to a tech. Link to comment Share on other sites More sharing options...
Guest HRB853370 Posted September 27, 2013 Share Posted September 27, 2013 I talked to a tech here in Greenville who is highly regarded. He said it is not the fuse because my indicator lamp is lit. He thinks it is the heater rail something or other (whatever the hell that is). He will install an upgraded one in place of the stock one if that is what it is. He said all the innards in these amps are Chinese crap and it just does not last. Link to comment Share on other sites More sharing options...

A friend had this happen to his Classic 30 and it was the heater lines. Many of these cheaper tube builds have "ribbon wiring" which is not a good thing. Chinese crap is the kind way of saying it.
