Hi, I just managed my Emerald Night with a 88003 (L-Motor) inside the boiler. I will post it in some days when I have some pictures. Here is just a picture to see the modification with the motor and the receiver.

Hello, just want to give some input to the 138 Electronic circuit. I already had one working 118 Train (but without whistle). Then I found on a marketplace one who offered the 138 Electronic Box, Microphone and the adjustable whistle for an really excaptable price . When it arrived I tested of course the whistel and the Microphone first and it worked like charme with my 118 Train. Then I tested the 138 Electronic Box. It was working Forward and Stop. Backwards it was working, but only on very low speed or even not. I opened the Box (which is really easy compared to the 118 which is glued). Then I noticed that two Transistors got very hot in the Backwards mode. T2 and T4 got quite hot. If you look to the circuit diagram (many thanks for drawing it) it seemed that T2 is not working propperly. That is a problem with the old Germanium Transistors... Luckily I had some stock of old Germanium Transistors from my uncle. I put in an AC180 as replacement. That was the only PNP with high current rating I had. Another types which should work are AC128 or AC188. At the end now it is working like about 50 years ago .
