Karma?

dr1978

Not sure if this would be a blessing or a curse, but...

I recently bought a Parasound HCA1200 on Ebay. When it arrived I could hear something rattling around and when I plugged it in, it started smoking. I was refunded, and rather than paying for the return shipping, the seller said I could just keep it.

If anyone would like to take a crack at it for repair or parts I would be willing to ship it at your cost. I could open it up and take some pictures if that would help anyone decide.

If you're in give me a number 1-100.

Open it and lets see some pictures.

Will do this evening

In in with a #52.

Please send pics via PM. I have a couple of things I need to get up on the bench. Always up for a challenge....and this sounds like a BIG one.

@WLDock I would suggest editing out your email and send in a PM....

I mean if you got it for free, I would hit up Big Sky audio and get an estimate. For the cost that they normally go for used you might be able to get one that's been refurbished by folks that know what they are doing...

Where are you at? And how much does it weigh? I would kinda like to get a shipping estimate. I’ll go in with number 75.

dr1978

Let me know if you want a closer up shot of anything

pitdogg2

Wow looks like torrid slipped and slammed into everything in front of it. It that correct? Any broken boards? To be honest it is hard to tell, something just looks cantiwhompus in the middle there....

Thanks for the heads up. That does sound like a good idea, but I'm going to take my time on my next purchase, I'm sure I'll end up with something solid. Hopefully someone here can fix this up for cheap and either use it or make a nice little profit.

There were some black pieces that fell out of the grill...

dr1978

Personally I think they knew it was broke when they sent it. I'm sure they insured the shipment...

mlistens03

DO you have any idea where the black peices came from? I looked for somewhere in the pictures that it would have come from, but I didn’t see anything. Are they plastic or paper or something else? They look like paper to me, but I can’t tell.
Is it the mark ii or the original?

dr1978

It's a semi rigid plastic. Seems like the same material that's around the power supplies in this picture, but when I looked last night I didn't notice any issues with any of them.

It's the original.

mlistens03

Ok, good to know.

nooshinjohn

Top right power cap by where the heat sink was dislodged. This is likely also to be the cause of the magic smoke...

dr1978

Ha, now that I look at the picture, it sure does look like there's some missing from the middle supply on the left. I'll take another look when I get home.

mlistens03

Is the front crooked? It looks kinda sideways in the picture.
Also, could you show pictures of the front panel and rear panel?

Oh yeah, I'm at zip code 24540 and according to the spec sheet it weighs 38lb.

mlistens03

OK, thanks!

mlistens03

Lol when I first got a shipping estimate it had auto selected ups air travel early next day, and it was like almost $350. I was very worried for a second.

I think that was due to the angle I took the picture from.

I did take some of the panels...

mlistens03

Goodness, what happened to the knobs on the front?

DaveHo

Water damage? The hold down plate on the toroidal is rusty too. This does not look like a job for the casual tinkerer.

dr1978

I'll have to take a closer look at the knobs. I did not remember them looking quite like the picture shows. But yeah, there does appear to be some signs of water.

mlistens03

This might be a little bigger of a job than I first thought... but I will do my best if I get it, and if my best is not good enough then I will... uh... probably get it fixed professionally or something

This thing looks like it got wet and or sat out in the garage or a damp basement for some years.

Just junk it @dr1978
