a long shot!!!!!!!!!!!!!!!!!!!!!

[craig87]

Right is there anyone on this forum or anyone that has a mate that can fix amplifiers???

I dont really know the parts that have blown but basically a lot of smoke etc came out and it looks to be transistors blown!! I cant really afford a new amp so close to christmas so hoping to get this fixed!!! ANYONE???

 

[richybigman]

Get in touch with a TV repair man, they can normally fix Amps.

 

[craig87]

dont really think i want a TV guy trying to repair my amp! Ive got no guarentee he can fix it, id rather someone who knows there stuff!!

 

[timmybiza]

what make is the amp and how old is it?

 

[craig87]

powerbass amp dont know how old its a pbx1500d

 

[timmybiza]

ok not sure on any where off top of my head, these guys do exsist, mayb best opption is to go to a local car audio install shop and ask them if they can fix it if they cant they normally know some one that can, i did that a lil while ago with one of my DLS amps.

 

[craig87]

well ive looked closely at it and due to the transistors being wired in parallel when one blows they all blow!! Checked price and there just over £10 a transistor with 20 blown up thats over £200 already so im guna buy a new amp!!

 

[timmybiza]

orion amps are good, cuple of mates are running them know i can get hold of them if you let me know wat power you need etc, or you could call paul at cai and say that tim with the green ibiza put you on to him

 

[craig87]

i tell you what mate, im looking for a reliable amp that is 1 ohm stable pushing out a 'true' 1500w rms at least for around the £250 mark, if you can get it for that then let me know dude! Oh and buy the way im selling my powerbass as spares or repair for £40 if you know anyone dude!

 

[Gm8]

you should get that for it on ebay . failing that try www.maplin.co.uk if ya feel confident with a soldering iron

 

[craig87]

im good with a soldering iron its findind the FETS that have blown for a decent price!

 

[Gm8]

im good with a soldering iron its findind the FETS that have blown for a decent price!

maybe look on ebay for decent faulty amps ?

 

[m0rk]

what's the part numbers for the FET's? Manufacturer info too if you can

soldering is easy, and sourcing the bits is easier still when you're paid to do it.....

 

[craig87]

m0rk i didnt realise i could ask you!!!

The amp is a PBX1500d its an american amp the company is called powerbass. As for the FETs part number i dont kno at the mo as there clamped to the heatsinks! Am i right in sayin that in the pics the burnt out items are FETs??

 

[jwmurdoch85]

Where'd you get the £10 a transistor price from?

Any chance you can unclip the heat sinks to get the model no's of the FET's?

You could then try one of these sites: www.rswww.com www.rapidonline.com uk.farnell.com as between them you can get most components (I'm guessing this is where you would look m0rk?).

If no joy on anyfront, as you suggest its american made and no joy for components on one of these sites give www.digikey.co.uk however digikey are expensive so use as a last resort.

From the pic's looks like impressive failure of some of the FET's, does the PCB look okay? Or is it just stained from the smoke / heat?

I've had transisters short out on lamp divers for traffic signals not quite the same kettle of fish but worrying when the tracks lift of the PCB due to the heat generated!

Hope this is of help, give us a shout if you need any advice as I dabble in electronics in my spare time.

 

[m0rk]

catalogues are 'ok' and may well supply to you - I was just thinking that I have access to a broader 'range' of places to look

they won't be a tenner though! - but as suggested, just remove the metalwork around them & get the info off one

 

[craig87]

tbh ive looked at the amp and i just want rid of it now, i have no doubt it can be repaired but i dont have the patients to fix it etc so if anyone wants an amp worth £250 if they can fix it ill sell for £40!

 

[richybigman]

At the end of the day an amp is just a PCB like you find in most appliances such as TV's. So if you know a decent TV repair man then they WILL be able to fix your AMP.
