Ersatzteile bestellen 		  Hi Stego... Thanks a lot for helping! I know it's really difficult to find replacement heads nowadays and that they probably are very valued! I will be very glad to make bussiness with you in case you find them

The tapes I want to transfer are all recorded in mono and SP; also, I like to high tolerance to loss of colour that my 2x4 seems to have for bad-quality tapes (the Interfunk tends to play more tapes just in B&W)... although who knows, maybe all that is also due to the head wear, too... Also, it would be great to have a working, full, top of the range machine for "sentimental purposes", too! Let's see what you have in stock

I guess I could have ended a lot quicker had I bought one of those expensive and "full working" machines listed on eBay... But also I'd missed the fun part of trying to revive them learning a lot ahd sharing thoughts with you and other users here on the forum!

yes, the power supply is faulty. This may come from dry capacitors, the voltages are not stabile enough. The switching power supply increases and decreases the voltages because of the dry capacitors (feedback from the secondary side of the transformer to the controller IC on the primary side).

I would change ALL electrolyitc capacitors in the power supply at first.
Next check the missing voltages.
If marked with (A), then the voltage is only present in "Record" (german = Aufnahme) mode.
With (W), the voltage is only at playback (german = Wiedergabe).
With (F), the voltage is for a special function.

Now the Interfunk Stereo 2x8:

The sparks in the picture can have different reasons:
1. The video heads are worn - no chance to repair.
2. the Dynamic Track Following system is not working correctly. Here, you must check at first the presence of the + and - 150 Volts from the power supply. Moreover, check ALL Voltages of this machine as well.
3. The pickup-shoes in the head drum motor are dirty or worn. For checking this, you must open the head drum motor:
- First remove the bottom cover (three screws)
- then also remove the upper cover and remove the meta...
