Silent Screamer Posted May 8 Posted May 8 Out of the blue my Halcro MC-70 amp got hot and went into what I believe was thermal shutdown. I let it cool down and the next day tried to turn it back on. The blue lights on the front went through their sequences flashing but it came back to a flashing red light without starting up. Who is the best person to speak with in the Brisbane / Ipswich area to see about repairs? Does anyone know if this amp has some kind of reset?
Guest Posted May 8 Posted May 8 Best speaking to @Magenta in the first case - the owners of Halcro. They might handle repairs in house or recommend someone local to you. 1

Silent Screamer Posted May 8 Author Posted May 8 I have never gotten the CD out of the case. I wasn't sure if it would be of any use now that it is non functioning. Do you know how to use the software / hook it up?
Silent Screamer Posted May 8 Author Posted May 8 CD was in my CD drawer. I am hoping the manual is still in the packing box, but that will be a tomorrow job.

Not sure if this means anything more to you than it does me... Guessing there is more than one power supply since it has the standby light on, and it is able to generate this message. - System - Provider [ Name] HRAS - EventID 9 [ Qualifiers] 49152 Level 2 Task 0 Keywords 0x80000000000000 - TimeCreated [ SystemTime] 2024-05-08T14:44:27.000000000Z EventRecordID 79148 Channel Application Computer WIN7PRO Security - EventData HRAS Alert [MC70, # A0000269]: POWER SUPPLY FAILURE Message: *S!:M03RA0000269P0V1110A0000000T1111111C1111111D1111111F1111111H01298847 Edited May 8 by Silent Screamer
brodricj Posted May 8 Posted May 8 The HRAS Alert is there as plain as day POWER SUPPLY FAILURE Send it to Lance at Halcro and he'll fit it with a new power supply.

But which one? If there is still a power led operating, and I can hear a faint clicking noise there must be some power coming from somewhere, I assume there must be an operational power supply for things like the LEDs and the software, and maybe one for the amp itself?
brodricj Posted May 8 Posted May 8 Mate, it's stuffed. Nothing you can do to fix it. It needs a new power supply. Pack it up and send it to Adelaide.
Silent Screamer Posted May 9 Author Posted May 9 Sent them an email yesterday morning, waiting on reply. 1
Silent Screamer Posted October 26 Author Posted October 26 OK so it has been way longer than I anticipated to repair this amplifier with a replacement power supply going in yesterday. Mostly because I got myself into some serious financial poo in the stock market and it wasn't really fair on my wife to then spend money on something for me. Good news is I finally got myself square with the stock market this week and felt OK with parting with the $465 to buy one of the two power supplies required. The front power supply unit was still working but upon close inspection I noticed that one of the resistors was damaged and the main power caps were less than happy. So after I repaired it that only left the rear one to do. I recapped it as well but it still wasn't working, so I admitted defeat and paid for a new one. I would still like to repair the old one as a spare. I can't believe how much I missed listening to music on my system.
Kaynin Posted October 26 Posted October 26 These are wonderful amps, and great to see still locally supported. I had one as NOS and a module blew. Magenta sent out a new one, but it took a tweeter in one speaker so that cost me a few hundred. My current mono (not Halcro) had a tube blow and took out some components. 6 months and $1750 later it's back home. Just hoping it makes you feel a little better... lol

I just would have preferred to fix it myself, sure the money is a part of it, but part of it is being able to do it myself. It could have been worse I could have needed to replace both of them, so I am semi happy that I could bring one of them back into a serviceable condition myself. Changing the resistor was quite tricky, as the resistor was difficult to get out. The holes were quite tight, and not much wiggle room for soldering back in. And considering what I know about electronics could be written on the back of a postage stamp, I say one out of two is not a bad repair rate. Edited October 27 by Silent Screamer 1

I don't have the courage!

The only reason I even give it a go was because probably two years ago my fridge blew up during a series of electrical brown outs, and I decided to see if there was something I could do. It was going to cost me a minimum of $450 (going off the manufacturers prices for PSU and service call minimum) to have someone come out and fit a new power supply, so I figured why not take a look. Was easy enough to get out and I looked for anything that was black and charred. Everything looked fine, but I did notice that one of the caps looked bulged on the end, and I had seen people say this happens when they die. So I went down to Jaycar, and spent something like $4 and bought two new caps. Change them over and like magic my fridge was up and running again. So it seemed only logical to see if I could do the same for the amp. Magenta told me how to check for DC voltage, and the front one was still working but there was obvious damage to a resistor and the caps didn't look happy, so its going to cost me $440 per module why not have a crack? Unfortunately there is something in the rear one that is a bigger problem than power caps, so it needs someone who actually knows what they are doing take a look. But I am back up an running so it is not a huge rush to fix. 2
