They also used to tax their cars by the amount of Horsepower. Anything over 195 bhp was taxed in the higher tax bracket.

In Japan they have lower tax for cars that will fit inside a certain size cube. They are called K cars I think. We've seen a few examples here.

Marcc or Ian .
I have had a look at the schematic and have come to believe that the active should be connected to the left hand terminal on the transformer/coil.
Would I be correct.

Hi Carl,
I don't think this will be a live chassis set. I have several German sets like this (I put an article in the most recent Radiowaves about a Sachsenwerk that I restored). They are very well made, but quite different to Australian and US sets. European and UK sets were similar in design. Valves can be harder to find here, and expensive, but the sets generally work very well. I'd be interested to know what others you have, or have access to...

This is one of the latter types where the mains floats only above the chassis: That is an "Auto transformer" / Ballast (no isolation from mains).
This was an attempt to make them a bit safer, but! The cap to chassis can put charge on it: It still should be treated as intrinsically unsafe. A lot of American sets, Neutral switch? This set cannot be grounded.
As that has a reversible pin set up & the way its wired it would be preferable to have active on the switch. Why in the hell they put the fuse & the line caps before the switch & why it is not double pole, beggars belief. No matter what happens one would never attempt to change the fuse with it plugged in (some would). The two 22nF caps on the line (mains), the one going to chassis & the one on the antenna need to be line caps: Replace if not sure. I would be tempted to put the line caps on the mains on the other side of the switch albeit I have them here permanently across the mains (RF).
Note that has two rectifiers. The one on the heaters is a "cold cathode" type. Running heaters on DC can reduce "Hum modulation" from the heaters.

Hi Marcc,
I just saw the circuit. You are quite right. An auto transformer powered set - quite dangerous if the AC lead is reversed. Not that its a good to spoil originality, but sometimes it s worth 'hard wiring' these sets to remove the chance of the ac plug being reversed.

Email sent. The guy has them listed on his website . He even offered to send me a pallet full at a good price but I like my marriage and had to decline lol. He also has spare parts . A very good dealer . my set was double boxed

Well guys I decided today was the day to start on this baby. Getting it onto the bench anyways was a start. It's very nicely built and shares the same valves as the Mullard MAS15. I gently applied power through the dimbulb and variac and got a fairly loud hum but that's no worries it just needs a recap. At least we have audio.
The rectifier is mounted on what looks like a transformer but it's separate from the main chassis and both are mounted on a wooden plinth . Well anyway I have the next four nights at work so yep back at it for really on Sunday night.

I wonder if one of you guys could check the schematic on radiomuseum and tell me what the value of the massive capacitor is that's mounted on the transformer physically behind the rectifier please.

You can fetch a copy of that schematic yourself. No need to be a member to get:
* A maximum of 3 documents a day.
* A maximum of 10 documents within 30 days.
Just double click on the big (left hand side) version of it and follow the prompts and it will be emailed to you.

The schematic is attached to the first page of this thread. The HT filter caps are a pair of 16uF.
The output valve has a 100μF on its cathode.

I can see the filter caps but physicality looking at the radio there is a massive capacitor mounted on the power transformer but I believe it is not a electrolytic.
It may actually be on the rectifier tag strip but it's not a electrolytic. It is about 2.5 inches long.

That set is rather typical of American & European sets of that pre-plastic everything era pre the introduction of the transistor sets.
Its possibly a case of they have big populations & stastistically they could get away with making intrinsically unsafe stuff, & improving the gene pool by bumping of a few of the careless ones.

It would be interesting to know weather the output transformer is functioning in light of the discussion recently of output transformer failures in another thread.
They haven't covered the windings in either the output transformer or autotransformer, which seems unusual in what is apparently a quality set eg dust cover for the speaker.

Windings in that look better quality than my 60S rolas !!
In 1989 when the Berlin wall came down I went to leipzig in East Germany. It was a time warp. All the shops windows were full of 50s Radios , cameras, toasters, etc etc All new ! But all ancient , nothing was modern in the shops because it had been cut off from the western world.
They had a very famous car which everbody drove and the taxis ,police cars, were the same brand, The car is made from type of masonite . No metal bodies ! Also the siren on the police cars were powered by the vacuum off the manifold so as you accelerate the Tone would go up and down like the cartoon cop cars!! Mow like a cat ! Fascinating place to see back then and I spotted Leipzig written on your Radio Which reminded me of my trip
Nice Radio!
Pete
