Hi all.
I would like to announce the resurrection of my forty-one-year-old Kriesler 59-01 CTV.
When I received this TV it was dead, missing several knobs, and had one castor broken off.

I was very happy to be able to get this TV being the first colour model from Kriesler and also a delta. It will go well sitting next to my sixty-year-old SJ Astor. Also the first of its kind.

After cleaning out the set and giving it a visual inspection, I began fault finding and had to replace one open mains fuse and a shorted tripler. When I went to my parts supplier I asked for a universal tripler. The man at the counter said “A what?” I had to show him in their catalogue. How times have changed. He works there forty hours a week and had never heard of a tripler. I remember changing them at the rate of eight to ten each week. After switching on and checking the B+ voltage I saw snow on the screen (very welcome) then a huge amount of smoke issued from the set. This turned out to be C103 across the mains. I replaced this with a mains rated cap with the less than assuring brand name of Suntan!

Again I switched on, and with the help of a test pattern DVD, a VHF modulator and a little time, I achieved a picture every bit as good as the day it came off the factory floor I am serious! Original tube excellent focus and perfect grey scale which I did not have to touch.

My concern about the electros was justified when another cloud of smoke issued forth. This time the main filter electrolytic failed. A replacement set things right.

A few other little things needed to be done and now all that is mandatory is to make safe the wrong power lead poorly joined? And insulated? To the original which had been cut off at some time in the past.

Wayne.

Good on you, it only seems yesterday that I attended the first colour training course at the Kriesler Factory
They were that good that I ended up convincing the whole family to buy this model.
Never looked back. Most lasted 20+ years.

Well done!

What was the guy's name at Kriesler? Bruce Pinkerton, wasn't it?

Yes they were certainly the bee's knees. I also recommended this TV to family and friends. And serviced possibly thousands of them under warranty, not the most reliable set but far from the worst either. It's strange how these days we take straight edges and fully converged images for granted, but this was one of the few TVs in those days that could actually give you that!

If anyone sees another 59-01 I want it!

I think the chap that took the courses at Kieisler, was either John Dunn or John Dunford.
Something similar anyway.

I recognise that colour control panel - now I know where mine came from! I pulled it out of a dumped set years ago because it was so pretty looking, and I had it on display for years.

1970s AEE Miniprint capacitors are absolutely guaranteed to explode on contact with mains voltage.

A valve a day keeps the transistor away...

Used to fix lots of those back in the day back when I entered the trade in October of '86 as they were pretty common back then.

Just as a precaution replace HV tuning cap (or caps) as they had a nasty habit of of going O/C and causing the EHT to go through the roof and the EHT goes to the nearest path to ground via the deflection yoke and puts a hole in the CRT neck causing it to go to air very quickly. Sad

The flyback tuning cap was only an issue if there were two in parallel and one went open circuit.

If there is only one and it goes open it takes out the Hor o/p transistor instantly.

I had a few of the former with catastrophic results.

The owners usually stated that the picture had been small for sometime before the set failed.

I wonder how many xray's wre given off while the EHT was high by goodness knows how much!!

The Philips K9 had the same issue.

Once the CRT was punctured the spark gaps on the neck pcb lit up like a Xmas tree. That was the first clue.

The lack of any CRT filaments was the confirmation.

Still they were a very good performer and left the Japanese sets for dead in the picture quality department.

A pleasure to work on also.

Actually the 59-01 (unlike the Philips K9) had added crowbar protection against that happening. It was very effective. I once did a service call in a beachside location where the cable loom to the convergence panel had come unclipped and was resting on the EHT connection on the CRT. Salt air and condensation had conspired to break down the insulation.

But the crowbar was firing before more than the tiniest spark could happen. All I had to do to fix it was clip the loom back into its intended place, absolutely no other damage! If this had happened on any other TV it would have quickly have become landfill.

I took the precaution of cleaning up the EHT connector of course, and advised the customer of the wisdom of their choice of TV.

Pity Kriesler dropped this protection in later models, I'm working on a 59-03 that has suffered badly from a catastrophic sequence of faults including holes burned in the PCB. This could never have happened in a 59-01.

A Philips K11 came into the workshop once and it was diagnosed with a faulty LOPTX (those things had the habit of burning up) and I replaced the LOPTX and let the set run on test and some time later without warning the HV tuning cap goes O/C and I watched with horror as the CRT went to air before my eyes. :'(

You're lucky the CRT didn't implode into your eyes..
