Recently a BBC Master was listed on one of the Facebook Groups I am on. It was listed as not working for £75 so I decided to grab it and try and revive it.
My assumption was that the issue was going to be the Rifa caps in the power supply.
So after waiting for Royal Mail to take a week to deliver a 24hr parcel, it finally arrived.
First of all I opened it up to see what we were dealing with. I was not surprised at all to discover the Rifa capacitors had indeed let go.
Luckily I had already ordered some replacements so a few minutes later, I had the old ones out of the board.
All of the other capacitors in the PSU looked fine so for now at least, I have only replaced the main culprits.
Upon putting everything back together, the BBC got powered back up and it sprang into life. Since the CMOS battery was also dead, I had to reset the settings and replace the batteries.
I really want to set this up somewhere where I can use it easily. So I think I’m going to look into getting an additional desk for my retro room. Hopefully I can setup some Acorn and Amstrad computers as I don’t have any out currently.
