Melburnians who can repair old machines

So I am a member of the Retro Computers Facebook group and someone told me there that I need to replace the electrolytic capacitors (caps) in my A1200 or some leakage will occur and destroy the PCB in the long-term,have noticed the warning signs already, including the internal floppy drive dismounting a disk if the disk is still in there, as well as the A1200 resetting itself. So I guess the sooner I get these caps replaced, the better.

So I'm asking if there are any people around my area, that will be happy to fix this problem?

Might have to do it yourself.

Once you have practised on your machine i know someone that wants there caps changed too.

Any technician who can solder at all will be able to replace the caps, but if there is already damage to the board, it would be good that the person knows how to deal with that.

I think there are 14 surface mounted electrolytic caps on the A1200 motherboard, these are the ones prone to drying out or leaking. There are another four larger, through-hole ones which don't usually leak, though it probably makes sense to change them at the same time as some of them are kind of in the way when working on the other ones.

I used a guy called Paul, in Mornington, somewhere, he is a member here but have forgotten his username.

He knew his stuff when he replaced the Audio in my 4000, and did the battery removal / replacement.

Here is his website, but dont know if its still valid.......

hmm after watching a vid on utube of it im not sure I could do it myself.

One place that offers to do it is amigakit, though you would have to send you a1200 to the UK for it to get done. I've bought stuff from them before so I guess it is an option.... I wonder how much it would be??

There's a guy up in Sydney that could replace the cap, but it involves a courier, so he would be my last resort.

I sent an email off to Amisynth, and got this reply sent to me not too long later...

Hi Troy,

Paul from Amisynth passed your email on to me as he no longer works on Amiga systems, my name is Paul also just to make it confusing. I have a workshop outside of Ballarat, Victoria, Australia where I repair and service Commodore, Amiga, Apple, Atari and other similar era machines.

A black screen on the Amiga 600 could be caused by a wide range of problems, it may be dead capacitors, faulty chips or other damage on the circuit board - it may even be a power supply issue. To give a rough idea of cost, if it's a simple repair it would be $25, and if all of the capacitors need replacing $62.50. If you bring the system in (or post) I'm happy to take a look at it for no charge and let you know what state the motherboard is in and what is likely to be needed for repair.

All the best,

Paul De Piazza

He has my A600 now to re-cap it and test to make sure it's functioning correctly before sending back to me. There is a bit of a delay, as I suspect he does this in his spare time, and I can't vouch for his work, as I'm in Tasmania and have had to send it to him, but you could contact him and perhaps go there if you've got the time?

Cheers Troy, postage both ways from my place will be about $60, might be better to have a go at it myself. I saw cap kits on ebay, and I guess some of the online shops sell them too. Time for an audit.

Cost me far less than that from North-West Tassie to just outside Ballarat, but I was only sending an A600, I guess an A1200 being bigger would cost more to send. But if you think you can do it yourself, more power to you mate, good luck! I know I couldn't - if I could, I would have done it myself. In any case, best of luck mate!

I didn't know that this thread was still alive.

Paul De Piazza has replaced the capacitors of my A1200, which were causing problems for the floppy drive, not only on the PCB, but on the MBX 1200z expansion board as well!

The best thing about Paul is that he's actually willing to travel around Victoria, going so far as Warragul, where he visits his parents. He can stop by your house if you want him to.

I am planning to upgrade the A1200 to have a better FPU than the one installed on the expansion board and to add more fast RAM to it, but I have no plans to contact him and ask him if he can install them, since I can't do it myself.

Cool, since I posted my response up above, he got back to me to tell me the repairs on my A600 are finished, and I'm just about to go to the bank to deposit the money required for payment for the repairs and parts and postage back to me. Times like this I kinda wish I still lived in Victoria, hahaha.

I thought I'd posted another response after I got my A600 back from being repaired by Paul De Piazza, but it appears I was too caught up in the excitement to post a response here.

Anyway, I can't recommend Paul De Piazza highly enough. I'm very happy with the work he did on my A600, and his pricing was most certainly fair, if anything I think he could have, and should have, charged more. I wouldn't hesitate to send any machine to him again to repair, and would recommend his services to anyone.
