List of electrolytics in the JACKSON mk 1

[cb4ever104]

Hi All .

I've got the service manual here for the Jackson but the parts list doesn't have the capacitors listed . Does anyone have a list of all electrolytics in the JACKSON ? Values and quantity ?

Cheers !

Merci Claude . I can see the restoration work that he is doing , and also there's a photo of the capacitors with the number "54" . Don't know if that means that there's 54 of them to change . Seems a lot . Well , I've got a standard set that I use for the PB-010 and EPT360011 boards so I'll just buy them and I'll find out during the process if I need any more .

Salut !

Probably ceramic disc capacitors. Seems to be a load of them in the pictures.

why ???

don't get me wrong and electrolytic's do fail..
but a lot of these radios are 30 years or older and probably never had a cap changed..!!
is this another american thing to adopt, re-capping every radio,
next it'll be swing kits and limiter mods when july arrives, and not forgetting ground everything in sight..!!

if it ain't broke don't fix it..
a simple cap in the wrong way, or bad solder can kill a radio, try asking the guy with the HR2500 that re capped a working one, he now has a nice door stop..

I learnt the hard way. I have broke several radios by messing around inside. Dropped my test probes in a few radios before today and shorted things out.

Thanks for the advice . I wasn't really asking for it , just a list of the capacitors and their values . If nobody has them then I'll track them down .

Cheers

...and when you found it please share! Just in case...

Last week my old mother found a cardboard box which I left in her house about 20 years ago. It contained my two Turner desk mikes and the good old President Jackson. To be honest I thought the whole lot was lost or sold ages ago.

I'll pick up the stuff in near future and believe me, when connecting the old PJ to the psu again I will keep my fingers, hands, toes and legs crossed.
I hope for a steady light and nice sound - NOT a small flash and the bitter sour smell of burnt electrolytic capacitors filling the room!

Good idea, one of the only components that wears out due to age.

Wonder if any of the eBay listings for kits contain lists of values?

There's a few people selling the Cobra 2000 GTL cap kits , but I haven't seen the Jackson . I don't think it'll be too different from the 148 which I already have . I'll start with them and note down any extras that might appear .

im with you on this its defo an american thing some ops in usa are changing caps in brand new sets and calling it an upgrade bang goes any warranty
as you say if it ain't broke don't fix it..

The title of this thread isn't "Who thinks it's a good idea to change electrolyics in a 30 year old radio ?" Someone else can start a new post on that subject if they like . If anyone has any information on the JACKSON then I'd be happy to hear it . If not then I'll post back with a complete list of them when I get round to it .

looks like you better get pen and paper ready

[cb4ever104]

In case it helps anyone . All values in uF . Voltage is minimum value .

10 25V x 7
0.47 50V x 3
4.7 25V x 1
47 16V x14
22 10V x 6
1 50V x 13
220 10V x 1
2.2 50V x 3
.22 50V x 4
100 10V x 1
330 10V x 1
1000 25V x 2

50v caps in a 13.8v radio
looks like who ever made the radio had a few laying about,
16v should be the maximum to use 25v at a push, but 50v ??

i can honestly say disregard the voltages above 25v unless the radio has some form of up converting power supply enabling up to 50v
