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

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.

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.

Ask bigclivedotcom ...at Youtube. Looka here, do you use a Mac computery? Don't plug in one of those hub thangys, just ask bigclivedotcom

Tubes last alot longer than paper and electrolytic capacitors.

Have you seen this

Kenwood R1000 Performance Upgrades
.....
Power Supply Upgrade

This upgrade replaces all the electrolytic capacitors on the power
supply board. Kiwa offers this upgrade both as a kit and a Kiwa
installed upgrade. If you find that the frequency display is
intermittent or holds on a particular frequency, it is time to replace
the power supply capacitors and resolder the connections on the voltage
regulators.

Power Supply Upgrade Kit $15.00
Kiwa installation of the Power Supply Upgrade - includes parts $35.00

Other R1000 upgrades: 1. Kiwa can also improve the sensitivity of the
R1000 receiver below 200 kHz (the stock receiver has very poor
sensitivity below 200 kHz) 2. Incandescent lamp replacement. The lamps
for the front panel display eventually fail. Kiwa can replace the lamps.

Address and tn of Kiwa Electronics is on pg

Now there's a blanket statement if I ever heard one.

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!

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'm old enough to remember those well. I had a beast Hallicrafters short
wave tube radio that I'd stay up much to late listening to. Good memories.
