The PHILCO Phorum

I accidentally managed to buy a rather rare and weird device - Garod 1C712D


Year of issue - 1946th. In fact, a very simple apparatus, one-band (Medium Wave), is almost the most simple and technologically cheap AA5, but with a two-stage output cascade. However, it has its own specific differences, which are quite substantially conflicting with each other ...;) I will start with the fact that the apparatus with trans-transformer power, therefore, works from both the alternating and the direct current of 110 ... 120 volts. As for the radio, there is no problem here - on the contrary, it even simplifies the design ... But do not forget that besides the radio we also have an automatic tablet player, in which the engine and which can not be as universal in the power supply. For the first time I saw that in the household apparatus for the life of the AC motor was used inverter - DC converter in the alternating! Very interesting thing.
 I think that in its basis the principle of the vibroconverter is used, although it has not yet studied its design ...
Unfortunately, this recorder does not work on the recorder, although the engine is running ... It's quite complicated mechanics and it's hard to figure out without a manual.
I found the radio scheme on this resource, but unfortunately there the inverter circuits.

So I have three requests to colleagues ...
1) Where can I find the circuit for this inverter? Model Garod typ 101. Does anyone have any experience with its repair and maintenance?
2) Where can I find a manual for repairing such players?
3) Where can I buy a cartridge?

Тhanks for the help

Hi;
  You do have a radio-phonograph combo of a very interesting design, and I think that you are correct about the purpose of the convertor box, have you removed it and opened it up? Most of those I have seen are for operating radios from 6 volt storage batteries, not converting DC mains to AC for an AC motor, though I have heard of such units. You could probably eliminate it, assuming that the motor on the record player is a normal 117 volt, 60 cycle, shade pole type, however that would not help you as the mains frequency is probably 50 cps where you are, so the motor would spin at a slower speed. I have a set of Riders manuals, but they probably won't show you anything that you don't already have, still I will see what they have on these sets if you can wait a day or two.

Thank you Arran. I welcome any information. Yesterday I opened this inverter and made a photo.

This is really a vibration converter
