Kenwood R-1000
Hi I have a Kenwood R 1000 , love it . . it developed power problems . i have since stripped the power board . .unfortunately I cant get most of the important parts . do you know of any second hand or new boards available I really want this radio to work again. Regards Peter ZS5 PX

Regards Peter ZS5 PX What parts do you need ? Nearly anything inside a radio of this vintage should not be a problem . |

Too bad it does not have tubes that can just be replaced. -- "What do you mean there's no movie?" |

But then you'd have all those paper capacitors that need replacing, and maybe it's old enough that the resistors have changed value and may need replacing too. Like he said, there's a period when most parts in solid state radios are still readily available. Maybe that's after silicon transistors took over, I gather those with HRO-500s have had some problem replacing germanium transistors (and probably the germanium transistors need replacing because they've gone bad over time). But it's also a period before large scale integration came along, so the ICs are plentiful but common analog or TTL. I can't imagine anything from that vintage in the power supply being really hard to get, a regulator IC might be hardest, but I suspect it wouldn't be something hard to get now. The rest would be common electrolytics, power diodes, maybe some transistors. They can be found, and if not, suitable substitutes can be found. It's later that seems to be a problem. Michael |

Tubes last alot longer than paper and electrolytic capacitors. |

My experience with the tube era was that a power supply would commonly have problems with either the rectifier tube or the electrolytics. Back then - as a teen, that is - I was a lot better at replacing tubes and swapping out electrolytics than I was at anything else, so take this with a grain of salt, but there did seem to be a lot of tube failures. The tubes that ran hot in the miniature tube versions of the All American Five radio - the 50C5 output tube and the 35W4 (?) rectifier - were the usual suspects. Nowadays tube radios, etc., seem to be showpieces and not actually used, with those ancient capacitors continuing to age while the tube filaments remain intact; so, today at least, the old tubes last way longer than those ancient capacitors! George P.S. The All American Five in my garage is still plugged in and still works fine at almost 50 years of age. Likely had a tube or two replaced over the years and little else. |

Do you remember that many stores had tube testers and some of those stores sold tubes too? I reckymember them. |

I had a beast Hallicrafters short wave tube radio that I'd stay up much to late listening to. Good memories. |
