Lafayette HE-30
#5

Today my order from AES arrived. I replaced the 2 section main filter condenser. The original condenser was 40mfd-40mfd at 300 volts. The new one is 50 mfd-50 mfd at 500 volts. It is a perfect fit using the original clamp, contacts fit exactly the same through the chassis hole. My tubes arrived too as part of the order. I will do a test on it later this evening, when reception is better. I am waiting on a 470 ohm 3 watt resistor to replace a 10 mfd electrolytic with a 1 watt 470 ohm resistor across it attached between chassis and the cathode of the audio output tube to create bias, but it may not be necessary. There are a few other electrolytic condensers in the set, all small values that one now uses poly caps to replace, which I will leave until after I give the set a test, and only replace if there seems to be a problem. They all look fine, no bulges or other signs of a problem. Here are pics of the new condenser installed...
