i cant see any other damage. i can take more pictures for you guys if you like, i you think its repairable then i'll give it a go.

Okay, so at this point I'm thinking maybe I'll pay a specialist to fix this, the tda was fun and simple but anything above pots and I'm not the most eager to be poking around.

Tda2030a fitted.
Buzzing remains.
Any thoughts, dry pots are my next idea.

Quotean apology and £15 off my next zoom purchase.

Make that  £10 cash and we are even  :lmao:

s
lol

Just to confirm.
The foil on the back of TDA2030 was still intact. I contacted Zoom and I was given an apology and £15 off my next zoom purchase. Several of The amps made around the same time as mine had similar faults. Xbox 360s get it all the time.

Will update when tda2030 arrive.

Completely forgot to reply to this.
630mah fuse in.
2hour live sesh.
Not a hint of trouble from the amp, it was perfect.


On a more awesome note
Any tips on recording guitar. I've set up a pretty decent studio, but my recording skill is drums and vocals
I'm guessing use my Warp7 and my studio guitar. mic up the amp with a ribbom mic @45 degree angle and use a clean bypass from my guitar as a backup raw recording, to modify and tinker with. Sound good?

The chip comes pre packed with a little bit of thermal paste. You peel off the foil and stick it to the heat sink,

cheap computer processors usually come with it.

So I peeled it off and the thermal paste was still fresh. The guy who built it in the factory must have forgotten to take it off before screwing it together.

The TDA2030a chip is visibly burnt so I'm still going to replace it. Then I'll Update you guys, parts are coming from Hong Kong so it may be as much as 20 days before I reply again. Unless you guys have any question's.

Kk here's the update.

Ordered 5 x TDA2030a
Took the old one ff to double chck part numbers and the thermal paste still has the foil on the inside, so its wasn't properly applied when it was made.

Gonna fit new TDA2030a then post update.

Thanks guys... much love.


Mike.

is this the chip your talking about?

My 15Watt ZOOM SS Amp makes this god awful Buzzing http://www.youtube.com/watch?v=a90r9CmQ8Eg

no matter what i do it wont make ANY other noise. not louder not quieter. guitar input make no difference either.

any ideas?

TY guys

the 400w isn't 500ma, there's a slot for a spare fuse in the holder, I read the spare fuses value. the main holder doesn't even have a fuse. thanks for making me double check that, I haven't ever got it to work and now i know why.

again. when i get those fuses i'll post up the results.

http://www.maplin.co.uk/Module.aspx?ModuleNo=452

These are the ones i will now get
I usually get the 500ma set, but 630ma is the next step up.

I wont be buying till Tuesday so there's plenty of time to reply in case these are.

Iv had a quick scan over my other amps and they all use T500ma fuses.
they range from 75W all the way to a 400W bass head unit.

Hi Megabunny.
I find 500mA a very small fuse value for your amp, even if it's written so in the back panel.
Is it a 100W SS amp?
It should use a 1A one.
In theory "120VA" power consumption from 220/230V lines would mean slightly over 500mA and fuses usually stand more current than rated, but it's too close for comfort.
Are you using *exactly* the same fuse?
Because it asks for a 500mA *T* type, which means a Time/slow blow/retarded/delay type of fuse.
Maybe you are using regular, not T fuses.
My theory is that there's nothing wrong with your amp, just a *too* tightly specified fuse.
Check that it's a "T" one, and maybe "upgrade" to a 750 mA one.
I usually don't suggest such a thing, but in this particular case the "official" value worries me a little.
Good luck.

it is a 100watt solid state amp. the fuses iv used have been slow blow or "T" fuses. i'll try a "250v T 750ma" and report back.

thanks guys.


BTW... its spotless inside. caps are all normal size. no bloating or residue. its surprisingly clean considering how dusty my house is. any tips for maintenance? do's and don'ts? although Ive been playing for about 10 years; I never really got into amps. or changing pick-ups. I have my gear unmodded..... STOCK!

on a Different note.
My gig setup ATM is pretty tight:
[AMP-Warp 7 / Guitar-Jackson Kelly (MEGA Glossy Black)] - Heavy Metal Crunch
[AMP-Warp 7 / Guitar-Gibson SG (faded cherry)]             - Clean Jazz Sound
[AMP-Fender Frontman series 100w / Jackson Kelly w/ Floyd Rose + WahWah Pedal] - 80's Metal / Solo Guitar - Looking into a SCHECTER DAMIEN Series 7 String to replace this.

What are you guys setup for?

i fix computers for a living so im not uncomfortable with components, im just not sure what im looking for... I'll Google for some burnt diodes and what not, then see if it looks similar inside.

any tell-tale sign to look out for?

heres and image of the rear panel
my fuse is 250v 500mah
