Just bought a nice Kriesler 11-99. Brown and cream in colour. Very clean. It suffers from distorted sound. Found HT. Very low,one of the 47mfd. electro's is open circut . Temporialy tacked another electro across it and it worked fine.
I have never needed 47mfd electro's before. I now have some on order from Carl , also ordered some of his black capacitors .
I was not going to buy anymore radios or do anymore repairs because it is becoming physically difficult but what can you do,you can only sit back in your chair for so long with your mouth open catching blowflies, and now the weather is much colder I haven't swollowed any for weeks. I also received the replacement element for my Weller soldering iron and fitted it today it is nice to have my faithful friend back in service again.
Regards Jimb.

Interesting, many Kriesler's have open output transformers. That should not have 47μF are they original B voltage on those is only a bit over 100V. Should be a 40μF (39uF) followed by a 20μF (22uF). Make sure their in right, its back biased & the first filter cap is not to ground. One tends to get hum if its wrong.

They actually say, on the data sheet to earth for good reception. Great, its got a shielded transformer, which will bleed charge to chassis. Those I normally fit with a three wire cable & earth it via the mains to get rid of that charge.

Hello Marc.
Thanks for your reply.
This must be one of the last ones it has solid state rectifier you can see it has never been fitted with the 6V4.
The radio looks original and spotless. Not sure if both elector's are 47mfd. I will be replacing both but I could not read the value on one. It tested ok however I will replace it also when I get some bits. I do have some 22mfd elector's anyway.
Regards Jim

Jim: could you provide us with dating information such as the set's serial number, a date stamped on the power transformer and/or date markings on wax capacitors.

Some 11-99s with a silicon rectifier reportedly had a 47μF filter electro.

If the solid-state rectifier was half-wave, it would explain the high capacitance.

Yes it is half wave. Even the earlier 11/99s with the 6V4s were wired half-wave. Go figure!

Should be no wax paper caps in that late production.

I've never seen an 11/99 that didn't work! They are super common in 2nd hand stores and I like to plug one in whenever I see it while the wife is rummaging for other stuff!

Ian ,I know your wife and she is minimalist. Hardly got anything in those 500 boxes .

Thank you all for your replies serial number 26463.
Yes half wave solid state rectification and Yay! not a wax paper capacitor in site. I get the impression it was a budget model made for the kitchen or bedroom with not a lot of sensitivity. Having said that still a well made little radio. I have a latter transistor radio 41-36 which uses the same case this is a great performer very sensitive. This pink and grey 41-36 is missing the handle if anyone has a scrap one I would be happy to buy the handle or the scrap unit.

Unfortunately someone has locked the thread, preventing us from adding your serial number to the list.

I had at one time a transistorised version, but it had been badly damaged by leaking batteries, and I ended up throwing the thing in the rubbish.

If it wasn't the last valve/tube radio ever to be in production, the 11/99 was close to it.

As I think I've said before, the 11/99 had a very interesting history at Kriesler.

1. It gave work to older assembly workers in the old part of the factory.
2. It used up reject 6GV8s from the TV production that Philips refused to concede were defective as well as other end-of-line parts.

Unfortunately someone has locked the thread, preventing us from adding your serial number to the list.

I've created a new thread in Tech Talk to cater for this.

Jimb, yours appears to have been made in the period 1970 to 1972. Are you sure there isn't a date stamped on the power transformer?

There maybe a date I will have to check. I had reassembled it till I got the parts.I did not want to leave it lying around in bits.
I will check tomorrow.
Regards Jimb

The 11 99 is very common and I come across them quite often. I like the 41 37 and they came in many colours and are stylish Radio ,but I don't come across those..
These days everyone is after colours and I'm no different .

The transformer has the following on it as I have also added this to GTC's tech talk post.
51873 7. J10 2 73. This last number is in large ink letters on the transformer insulation.
Regards Jimb

I have looked all over this radio there does not appear to be a date stamp. There is a blue sticker AC430270 .
