  1 I need help identifying several paper capacitors on the Grundig 2066 schematic.

C5X 0.1uF 250V (near R31). Need to verify C number and value.
C62 6.8nF 500V (near R37). Need to verify value.
C64 0.15uF 250V. Need to verify value.
C65 6.8nF 250V. Need to verify value.

Thank you,

Jeff

  2 In restoring my Grundig 2066 I noticed a 4uF 70/80 V electrolytic capacitor (according to the schematic). What would be the best way to replace this? Use (4) 1uF caps in parallel? (at least 80V value of course).

  3  Hello Mr. Miller,
the correct values are:

C58  0,1 uF or .1MFD

C62  0,068 uF or .068 MFD

C64 0,15 uF or .15 MFD

C65 0,068 uF or .068 MFD

For the C47 4 uF 70/ 80V you can use:
4,7 uF or 4.7 MFD 63 to 100V

The greater value (4,7) have no affect on his function on the radio.

Normal tolerance of small electrolytic capacitor's are +/- 20% up to 30%

Best regards, H.M. Knoll

  4 Thanks Hans.

Is C40 6.8nf or 68nF (0.0068uf or 0.068uf)?

C40 is below the EF89 tube in the schematic.

  5 Hello Jeff.

C40 is 0,0068uf or .0068MFD
also C39 is 0,0082uF or .0082 MFD

  6 Hi Hans,

C39 is designated "Styroflex" (according to the graphic legend at the bottom left of the schematic). Should I also replace the Styroflex caps (what is Styroflex?) or just the paper caps ("papier" on the schematic).

  7 Hello,

C40 is 500V paper,

C39 is   500V keramic.

Styroflex means: polystyrol 
mostly used in the RF/ IF_section.

  8 Hans, That's a nice looking copy of the schematic. Thanks. I have that section too but it looks like it was already copied several times by the time it was made into a .pdf file. Thank you for the help sir. This is a great group. I ordered my parts today for the Grundig 2066 restoration. It's on my bench now but I just needed to get the parts ordered. Jeff

  9 Hello Jeff,
that's fine, i am glad.

The World is small, 47 yeahrs earlyer, this model was on my workbench at GRUNDIG Laboratory.

  10 I am still working on this radio (14 months later). Today, I measured -1 vdc at pin 1 (grid) of the EM84 magic eye tube when tuned into a strong FM signal. The phosphor bars are not closing at all when tuned to a strong signal. What is the correct range of voltages at pin 1 of the EM84 with a good FM radio signal?

Correction to the original post: I measured -1 vdc at pin 1 (grid). Not 48v as previously indicated. Verified R21 is 470k. Measured ~230v on other side of resistor. Need to investigate why there is only -1 v at the grid. Need to verify R15 2.2M (when I can locate the resistor).

Thanks for the reply Hans,
- Jeff

Hello Jeff,

see here http://www.radiomuseum.org/tubes/tube_em84.html

you can find, minus 22 Volts are neccesary to close the bars.

I think, the R21 = 470 Kohm is interruptet or  its value  is infinitiv.

When the Voltage on pin 9 ist to low, the bars are not closing.

regards Hans
