Michell Gyro 'VC' (DC) power supply dead

[johnfromnorwich]

It's just stopped working! No green light, nothing. Was working fine this afternoon. It's not the fuse in the plug. Anyone have any background with these? Internal fuses maybe?

I'll ring Michell tomorrow, but any hints would be appreciated.

To partially answer my own question, the little output fuse is measuring infinite resistance so I guess that at least is blown. No other signs of burning on the PCB. Anyone know what the rating of the fuse is and whether I can get one in Maplin?

Sorry no ....but it should be stamped on an end cap of the fuse...

a blown fuse may indicate problems elsewhere ....be prepared to have the next one blow too ! [don't just by one !]

I spoke to Michell this morning and they said much the same thing: If it ain't the fuse (100mA for reference), send it back. Grrrrr.

I thought you conclude it WAS the fuse! Buy a new one and try again! Costs a few pence!

I concluded that at least the fuse had blown, but that this may have just been the end of a failure train. Fuse now replaced, power supply working, owner happy (although not with Maplin's postage policy - about 2 and half quid most of which paid for them to stuff a large envelpoe with junk mail that weighed about 50 x as much as the fuses).

Reviving an old thread here, but incase anybody's curious, I just revived my old Gyropower VC.

The toroidal transformer in it had a dead short but after fitting a suitable replacement (RS 671-8990) and adjusting it accordingly, I'm happy to say I'm back up and running.

I DID try to contact the original transformer manufacturer (TMC Ltd.) but unsurprisingly, I got no response.

Hope someone finds this helpful.
