Hi guys,

Im hving a problem with my amplifier and need some sort of assistance,
i emailed the company and they just said 'the transistors might be blown'
how unhelpful but heres the problem:

I've been running this amp for mobile use for just over a year now.
However it has developed a fault. The power input fuse blew so I replaced it with the spare included which worked fine for a while but then blew.
I've tried a few more matching 250V fuses that have also blown.

What happens is, you put a new fuse in and turn on the amp, instead of the power and protection LEDS coming on at startup, the power led comes on for a split second then goes off.


^ thats basically what i wrote in the email to them so if you guys here on DJU could help id be greatful, also is it the transistors and how much do you think itll cost 2 be repaired?
is it repairable?
or is it beyond economic repair?
Should i get it fixed or just buy a new amp?


cheers guys

btw the amp is out of warrenty

I've got a DA800 that was loaned to a friend- came back blown (I suspect both outputs were connected to the same Speaker). Drat!

From chats with a few people here, as a budget AMP, its not worth fixing (unless you can DIY)

I now have a replacement, as the DA800 was my back-up.

Generally, fuses don't go for no reason - if you do replace the blown one and it then blows again... it really needs attention.

Perhaps ask the advice of the company you brought it from. Perhaps they can offer a quotation for the repair - at least you'll be able to weigh up the pros/cons.

hey jason cheers for your comment .
you said the outputs were connected to the same speaker.
even though thats a bad idea could it be the speakers that caused it,
im hoping its not and is not i think because u get the same problems wiv the speakers not plugged in

No, in my instance, I think that is what caused my amp to blow. The guy turned up with a Corsa full of people, and could only fit one speaker on his boot. My amp is flightcased with cables coiled in the back of the amp (and so spill out when you take off the rear case cover. I think he saw 2 cables and plugged them both into the speaker.


Your problem could simply be a knackered amp :-( or cables, or very possibly the speaker.
If the speaker has been sounding "funny", or has physical damage (speakon socket loose etc), then it should be checked out.

Best to test/check your speakon cables (which you may have already done)

the speakers were working last time the amp was up and running and they will be fine,
the drivers in the speakers dont have any damage but theyve been gigged so the actual cabinets are a bit bashed up but thats not gonna kill the insides and the leads are ok

Usually output transistors gone or possibly the rectifier.

Since a small amp can often cost as much to strip down as a large one (time-wise, everything's glued), the smaller ones are rarely economical to repair unless they're a high-end model from a premium brand. This is neither of those!

Estimate around the £50-60 mark unless you can get a mate to do it out of love.

cheers for your comment...

theres a few things im left with then:
im waiting for warrior to phone me back
if its beond economical repair will either:
A) sell it on ebay for spares and repairs
or
B) just leave it sitting around collecting dust
or
C) it dosent work so it makes a good paper weight



so what should i do what do you think if you were in this position what would you do

cheers

Best to cut your losses with this one. I used to sell the DA range and always found them under-powered. I once measured a DA1000 (2 x 500W) flat out. It was giving about 850W and clipping. Made me wonder what the clip limiter was actually doing.

You can't get schematics to repair them either. The Chinese factories won't release them for fear of the designs being copied. Apparently they don't approve of counterfeit goods over there! But I digress.

The bottom line is that you get what you pay for. If you get 2 years from a budget amp you've had your money's worth. If you can't stretch to a 'branded' amp there are still some budget ones out there that are pretty good. Have a look on the net for models and prices and then try to find some impartial reviews through Google.
