Re: Marconi 272 skip find
Thanks everyone for all the comments !
I'm beginning to wade through all the information and hoping that with your help, it won't be long before all its valves are aglow again!! I have to say that I'm struck by Geoff's' comments about keeping its patina and this is probably the way I'm going to go. That said the thought that it could be a 00001, with the 06 a model prefix actually frightens me ! It would be a bit too important, for an amateur like myself, to be let loose on it charlie |

Re: Marconi 272 skip find
How awful that someone just skipped it. Looks essentially complete, including valves, and the silvery effect ("gettering") visible on a couple of them suggests that they are still viable too. As mentioned, an interesting evolutionary stage in radio development that will still give good results more than 80 years on- but something this old will take diligence and care in overhaul. There's plenty of appropriate good advice to be found from forum members. Good luck with it.

Re: Marconi 272 skip find
The most important piece of advice i would give is not to simply plug it in and hope it works!

Re: Marconi 272 skip find
Hi Charlie
On a slightly negative note, I hadn't spotted earlier that this is one of the sets from the EMI* stable that uses a capacitor block. This is a box containing a dozen or so capacitors and then filled with black pitch. This was a deliberate ploy by EMI to discourage non-EMI dealers and DIY repair men from repairing their sets. The implication here and now is that replacing the capacitors in the block is a relatively challenging job for a "newbee". You may be well advised to find a forum member in your part of the world who can do the chassis restoration for you or at least rebuild the capacitor block for you. *EMI = Electrical & Musical Industries, they manufactured and distributed radios etc under the Columbia, HMV & Marconi names. |

Re: Marconi 272 skip find
Was just reading about the capacitor block in the link posted earlier. Have now removed the chassis and speaker but will decide later on whether I need professional help !!!! Need to do more reading. But in the meantime am taking a mimimalist approach to the cabinet. Veneer to clamp back down
and glue, new perspex dial screen, speaker cloth and lots of head scratching. Charlie |

Re: Marconi 272 skip find
here's a small insight into Marconi numbering, in this case from my data on set type 911
( small bakelite job with the chassis mounted upside down ) 911 A/5 7262 911 9057 911 9451 911 a/4 100946 911 a/4 103154 911 G4 ? 103676 911 104300 911 A/4 104350 911 a/4 106762 911 109021 911 111677 911 A/4 116702 911 117664 13 38.88% 16719 Whilst one doesn't know the starting number, it does appear that the numbering is consecutive, ( some sort of 'reset' seems to have been done after 9999 ) and in this case its possible that over 16000 were made !

Re: Marconi 272 skip find
If that isn't inspiring enough to restore it, pitch block included, nothing is!

Now, does this point to my radio being one of 60,000 made, which is of course a very likely possibility or its the outside chance of it being 00001 of a 06 series? The only thing I can deduce ( in a poor Sherlock Holmes moment ) that there are no numbers beginning with a 0 prefix in your list, which doesn't really help given the other comments over the vagaries of serial numbering in general. The only other 272 I can find are on Radiomuseum site and have e mailed them in hope of getting the other serial numbers sent to me in an attempt to solve this mystery !! charlie |
