That's ok. Now I have to 'eat' too!!... Garlic King Prawns!!! xox ;D P.S. What Americans call 'Shrimps' are NOT PRAWNS!! 'Shrimps' are tiny things about 1 to 1&1/2" long. PRAWNS are about 4 to 5" long!!! When the likes of 'Paul Hogan' years ago, was selling 'Australia' with comments like... "Come to Australia & put a 'shrimp' on the barbie', it was PURELY aimed at the American market!!! We never did any such thing!!! Least ways, with tiny 'shrimp' that the likes of a 'Whale' might eat!! ;) haha... ;D |

I remember, back in the day, seeing radios where a circular metal "patch" was placed over the old large tube cut outs, with a miniature tube socket mounted in the middle. These were quite obviously factory modifications, as the workmanship was too good for an aftermarket "bodge". |

I'm still not sure why it is wired to a base for the 'Magic-Eye', but not included. Maybe it was just a 'cost' issue, but when I re-build it, it will have one!! :) |

Glenn, sorry to reopen your old topic. I finally found time to work on my BX462A and I was able to recap it and put it to sing again. Now, on to eternity of service - apart from the tubes and the three electrolytic capacitors. I documented the journey in a series of videos - if you are interested take a look below and hopefully the automatic subtitles work well enough. |

I knew someone who would take apart the "cans" in old radios and stuff in modern capacitors. His customers paid a good price for that. |
