Hello! & please pass the fire extinguisher...

Post by blutaQ » Wed Aug 22, 2018 7:38 pm

Good evening all.

Very pleased to be here. My story is like many others, Just taken a delivery of the classic package - box from the attic of my parents... Contents ~ acorn tape player, various cassettes and a very unused looking BBCB ( I must thank the "always put the cover on after use!!!!" attitude of my strict father - no or very little sun damage!)

So, I google the BBCB monitor to scart options and settle for the RGB to Scart converter cable from Fleabay..

A pause..... "I wonder if it stills works?" probably should have tested before buying bits...

I turn it on and "WOW!" the sound of my childhood.... the start up beeps... a small warm LED light...

I turn my attention to the games, looking for the favorites. A few minutes pass...

As if like a cartoon bear attached to the scent of a pie in a window.. my nostrils are hypnotised by a smell.... BURNING...!!!!!

I frantically turn off the computer as large whisps of grey smoke accend from the machine of broken dreams... sad face..

So I'm a forty something musically minded chap in South East Devon with a broken BBCB, looking for any advice on were to start the fix... will begin the opening up and learning to operate at the weekend.

All thoughts welcome,
and thank you for your time.

Welcome to the Forum, blutaQ . . . Enjoy . . .

Ah! The magic smoke :D Don't worry too much, it's not fatal! If you can stand the smell, you can carry on using your Beeb. If not and are handy with a soldering iron (?) it's just 3 x capacitors in the power supply - There's lots of information on the Forum on how to replace them. Finally, if you don't solder contact Mark Haysman at RetroClinic - he'll be able to fix it for you.

Welcome, blutaQ. :D

That burning capacitor smell is awful. It stank out my mancave for weeks! And this was a newly replaced, full-spec capacitor less that 12 months old. :(

Weclome.

The magic smoke is the Beeb's revenge on being negleted for decades ;-). I should think most people on here at one point or another have been through the magic smoke. For many it is there first soldering job for years.

Welcpme,
now your are a proper member of the club ;)

The soldering is easy if you have any soldering experience, but you might end up a little wounded getting into the PSU.

In the mean time you can use it but if it hasn't finished smoking, you will probably make the smell worse - yes it is possible ;)

Thanks to you all, nice to hear from you.

I have gathered your great sense of optimism, taken a trip to youtube land (the process is well documented there ) and ordered the 3 replacement caps.

i'm now hoping for more apple pie rather than the burning smelly metal socks....!

Nothing like the smell off burning 80s PCB on your first attempt to swap out power caps :)

I was lucky to have my Beeb's capacitors blown by a previous owner, but my Beeb did give me my first experience of desoldering DIL chips!

Not just negleted ones, it used to happen to brand new ones, factory could have gone up in flames a couple of times.

It was fortunate that on the two ocaisions that I recall of beebs bursting into flames, the night security guard was quick and handy with the fire extinguisher.

A rack of a couple of hundred beebs on soak test catching alight would have been quite spectacular.

Sprinklers - who needs them ?
