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). |

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: 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

Thanks Hans. Is C40 6.8nf or 68nF (0.0068uf or 0.068uf)? C40 is below the EF89 tube in the schematic. Jeff |

Hello Jeff. C40 is 0,0068uf or .0068MFD also C39 is 0,0082uF or .0082 MFD Hans |

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). Jeff |

Hello, C40 is 500V paper, C39 is 500V keramic. Styroflex means: polystyrol mostly used in the RF/ IF_section. Hans |

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 |

Hello Jeff, that's fine, i am glad. The World is small, 47 yeahrs earlyer, this model was on my workbench at GRUNDIG Laboratory. Hans |

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 |
