开云体育Hi Francois, ? I did not document my changes and sold the amp a few years ago. ? I remember the green capacitor (B) but not (A). That could easily be a memory leakage on my side but I couldn’t find it on the pictures before the restauration. . I don’t know the values of the (B) capacitor but replaced it with doorknob type (red). The red wire to the capacitor is spark-plug wire. On the attached picture you can see the new RF-choke was placed. When I looked at the photo’s I made, I saw I did change the indicator assembly as well. ? Do you have the service manual of this amp? ? 73, Evert ? / / ? From: [email protected] <[email protected]> On Behalf Of Fran?ois via groups.io

That was all. ? Hello ? I am weak in technology (I am 75 years old). It seems to me that you are pointing out the two curious plate capacitors A = C41 (47 pF) and B = C42 (307 pF). ? ? Could you give me, precisely, the replacement capacitors that should be supplied. A url would be welcome. ? -- F1AMM Fran?ois De la part de Evert Bakker |
