Hi, I am refurbishing a 1937 McMichael 137 Tuner. So far I have good reception on all but the Short Wave band but the T.V.4 Tuning Indicator does not light-up or register on/near/off a station. I am trying to source a repolacement . Any suggestions as to supplier or alternative? It looks like the attachment. Thanks all, Geoff Attachments:

Dear Geoffrey, The tube is very similar and one to one exchangeable to the German type AM1. As this is a more used type as the TV4 you may get a AM1 at ebay. But it will be difficult anyway and expensive too. Be prepared for 70 to 100 Euros. If you are able to change the socket you can use the 6E5C from Russia. But this tube needs 6.3V heater. These tubes you will get between 25 and 35 Euro. Regards Rolf |

Hello Bernherd, Thanks for responding to my query. I have now located a supplier for an alternative to the TV4. However, looking at the exorbitent price being asked, £148, yes 148 pounds, I may reconsider. It is possible to get a far cheaper alternative but it would then require a different fitting to plug it in ..... we shall see! I did find a full schematic of the tuner on the site which had been uploaded by Howard Craven and which I have successfully downloaded and have to hand. Not sure where you are but we in the UK have just been put in a full lockdown again so I wont be going out any time soon. Hopefully I will manage to get vaccinated by the end of February, one advantage of being over 70!, and then life may return to a degree of sanity. Regards, Geoff
