Hello,
I'd like to share with you one of my biggest works - restoration of Ingelen 640W, which, judging by the amount of photos and information on the Internet, is even rarer than Geografic models. I bought it on Aukro.cz in 2015, for a staggering sum of 40PLN (around 10 Euro). No wonder, there was only one blurred picture, additionally it was visible, that radio was "a little" worn out.
But after checking, it turned out to be a very rare radio, so I decided to bid no matter what condition.

The radio came from the Czech Republic, well packaged, but that did not help much, because the housing was in such a state that it fallen into parts as soon as I unpacked it. Surprisingly, the chassis was more or less alright (aluminum), and the steel elements were not corroded beyond recognition. Both the back and the bottom wall were original as was the cord. After the inspection it turned out that unfortunately it was repaired in the Czech Republic and the motor was removed, the transformer and band switch were changed and the short wave coils were not original (original coils were obviously removed during the WWII).
The housing was the worst part. It was not enough that it was in parts, and everywhere the veneer was peeling away, from the side the entire sheet of veneer was missing.
The decision was made that veneering of the whole housing would be the most reasonable thing to do than to fiddle with saved parts of veneer, adding new ones, cut exact parts etc.
I asked many carpenters - they either don't do that, or don't have time, or it would be too expensive, so that was not a good solution. There are a lot of restoration reports with veneering, so I decided to try it myself. I bought a walnut veneer, I talked a lot with a carpenter, I read some posts... And it came out like in the pictures.
The next job was to bring chassis to a more original condition. I bought a badly damaged Ingelen 540W for spare parts - range switch, inscription, transformer and more. Also I removed steel parts and took them for galvanization.
The transformers were almost identical in both radios, the 640W had a slightly larger heater winding to have symmetrical 2x8V output for motor control. I have not wound it yet, since there is no motor anyway.
The 540W band switch had to be "reprogrammed" because the 640W had an additional two ranges called UKW, or more precisely UKW1 (AM) bands, 4.8 m - 13.5 m and
UKW2 (AM) 9.6m - 27m. I had to modify a few of the switching parts, making the missing cams from two-component putty. After a long thinking (the contacts are grouped in an even and odd numbered way on both sides of the cam axle), I managed to make the switch work as it should in 640W.
There is one more problem. Somewhere on the switch's axis there had to be a second switch, switching the scale bulbs and switching on the turntable socket. Also 6-way with countinous rotation. Problem is I have no idea what was that switch, how it looked like and how it was fitted. I suppose it was identical in Ingelen Gigant 40, but it is also a rare radio and the owners do not really want to pull out the chassis (I'm not surprised, it is large and bulky) and from underneath it can not be seen, because it's covered by housing..
So at this moment there are three things to solve before doing any work:
1. find the motor
2. find the lamp switch
3. find KW and UKW coils.
Hope you enjoyed my work so far
Regards
Piotr
