A colourful Decca arrives: Decca CS2230
Hi all, today Father Christmas (aka Cathovisor) brings me an early present.... Yipee !! Thanks Mike
It is a Decca CS2230, a 22 inch set dating from 1973 and I have not seen this model in the flesh since 1983/4.
The cabinet needs some attention, but that is a long way off yet. First job is the electronics, naturally, and I am pleased to say that Chris has already tested the CRT and it is good. I wonder what the scenery will be like as we enter the aerial socket and travel through the set finally into the tube and speaker......
An inspection of the new arrival is called for.

It´s a very nice looking television, im suprised over it still have tubes, the pcb board with the tree colour outputs is a little bit similar to my Rank Arena television, what types of tubes is in the set? great that the picture tubes is still good, thats the most important, everything else can be fixed
Alex 😉
Are those stand-off valve-holders original or a later modification?
Also should those loose wires be hanging so close to the valves?
Wow! Only been through the door ten minutes here and already the Bradford's had its back off and been posted about!
Looking forward to reading more about it. I do have NOS tuner units for these BTW.
Hi Alex,
Tubes are.... PCL82 sound, PL508 frame output, PCF80 sync separator and frame multivibrator, PCF802 line oscillator, PL509 line output, PY500A boost diode.

I would say they are original, and no, the wires should be and will be better arranged in time.

Looking forward to getting it on the bench, but just one minor problem though..... a bit of a tidy-up is called for first in my workshop don't you think?

There could well be a very good reason for the close inspection of said telly....it's previous custodian (well for the last couple of months or so) has been my cat Hattie and she takes her daily guard duty routine very seriously. Make no wonder your pooch's sniffing organ is in full flight.

Haha ! Both dogs sniffed over the entire set, Sally the black one could hardly keep away !
Well I have found some bench space and had a look inside, the mains fuse had blown so of course no way am I going to just apply power and hope.
Firstly, I replaced the fuse and snipped the mains RF filter cap. Then I checked over the chassis and could see no obvious burns or damage, so onto taking the main smoothing can out of circuit and reforming it. The first section reformed quickly, but the second is taking a little longer. I'll see how this goes.
A mystery object was found inside the set affixed to a nut on the control panel. It is a hand-crafted nut runner, and I wonder if it belongs to the kind person who replaced the on-off switch......Chris ?

Snipped the RF bypass cap and replaced the mains fuse.
A peep at the PCL82 sound output.
In this shot, you can just see the mystery object on a nut, just to the lower right of my thumb.

OMG! I've been looking for that for over a year or more, its part of a set of six from an old 1940's toolkit I use. I had given up all hope of locating it. Why on earth I left it in there is beyond me.
Yes I must have used it when doing the only work on that set in six years of owning it, namely replacing the duff on/off switch.
Don't suppose you could post it back to me, all costs covered of course.

No problem Chris, just PM your address and I'll pop it in the post.
It's amazing that it remained on that nut during all of the transportation !!
It will soon be reunited with it's friends

INDEED it look like my room where i get the televisions and radios back to life.... the wife tells me to clean up, i dont know what she means at all 😛
Thanks mate for the answer about the tubes, they are almost the same in my Philips K80
Alex 😉
This mixed dielectric capacitors for RF bypass were notorious for going S/C but there was very little else that could be used at time. No X or Y rated caps that I can remember, then the Rifa caps came out and they still went bang.

It looks ok, not split open, but will be replaced at some point.
Good news ! The main smoothing can has reformed nicely on both sections now. Just have to solder all those red wires back on...... Tomorrow now.

Once I get a new workshop built, things will be better.... I hope.
Quite likely Frank, but the intention is to have my existing workshop for storage only once the new one is built.

Pleased to see it's arrived Andrew and I will certainly be following your progress.

After reforming the main smoothing capacitors C601/2, I will check the condition of D600 too.
Someone has been here before......
The timebase board, I thought I would remove it to give easier access to the PSU pcb behind.
A previous repair on the timebase pcb....
Also some minor damage.....
But nothing too serious that cannot be repaired.....
The boost capacitor has not been replaced and unsure whether I should do so now or test the set first......
