Thought you guys may be interested in this. Had to empty my Nan's loft the other day as shes having some new insulation put in. The hatch hadn't been opened since the early 80's (which proved a problem in itself) when my granddad died, and nothing had been removed since the 60's. Among the typewriters, hat boxes, Indian instruments  , cine cameras, model planes, my granddads army uniform and various parts of my dads MG TD thought to be lost to winds of time I found this nice Bush radio which was kindly given to me  . It's a BAC 31 if that means anything to anyone...   Very nice I thought! So I opened the door on the back to check if all was well (I don't like spiders  ) and found these...    Check the date!  My Nan can even remember when when my granddad brought it home! |

Runs off the mains?
Do you know how to check it over before you plug it in?
Would be worth checking the caps at least, check the resistors if you can too.

That nice that is. Must be equivalent to buying a £500 TV these days.

Very nice find. I'd get it looked over before attempting to power it up - some of the valves in these things can be hard to replace if damaged. The instruction manuan says that it's a battery or mains (200 to 250v, 40 to 100Hz) model. The battery models are listed on the sales receipt: Battery model B107: www.the-thompson-brown-family.co.uk/batteries/pages/b107.htmThat is the high-tension battery, 90v DC. There isn't much out there on the AD-31. did find this though: www.vintage-radio.net/forum/showthread.php?t=292297.5v would be the filament supply or possibly the bias supply - heaters is more likely though.

The only problem you might have is the capacitors used to be wax filled and they can dry out. When you plug it in and they've dried out they can catch fire. What you should do is take a good pic of the circuit close up on some of the capacitors and a visual check should be good enough to say if they are ok or not, assuming it has wax filled caps. Obviously just keep an eye and a nose on it but it should be ok. You could also ask on that forum what it has. Old valves can lose their vacuum, then obviously they don't work, but they aren't dangerous when this happens.

I'm debating whether to try and power it up at all to be honest. I'ts been in a rather damp loft for over 40 years, yes this means its in great condition with no marks or anything like that but it gives rise to the possibility of corodded terminals, joints etc which will obviously cause problems and may mean the replacement of certain items. I'd rather keep it original. I usually conform to the "It's there to be used" philosophy but as rav say's its kind of an hier loom  I've got a mate who's a qualified electrical tester and he's into his retro stuff too so I'll pop it over to him and see what the diagnosis is  I'll try and get a few snaps of the instruments aswell if I can. |

You might be lucky. As said above, the usual problems with old electrical gear is knackered capacitors. I've had a few go bang over the years. If you decide to try it out, there's some good info at www.vintage-radio.com/repair-restore-information/index.html - the lamp limiter is the first basic step. Hopefully your mate will already know about this, but just in case... I can understand the desire to keep it as it is, but for the sake of the odd component, listening to long wave Radio 4 on a valve set is a very cosy experience! |
