    The caps on 3 & 11 show no ohms. The one on 12, the filament shows a small number of ohms. All the pin sockets check out ok. 238

    MACO / BRUTE Seventy-Five

    If the .005 caps, that go to ground on the tube, are bad will that cause the tube to turn red? I have already changed the coax to 316 an grounded the shield on both ends. 238

    Maco Super 75

    These have been in my shop. Never been used. Most are 1/4 watt. Do they still make new carbon resisters? I have carbon film/ metal oxide + others. I am just not sure what kind to use. Thanks 238

    Browning MKll 180

    Thanks a lot.I have had so much trouble finding info on a MKll 180. So i included pics of mine. The only things that look to be changed are the caps & it has 6KV6 tubes. All the resisters check ok. Could not check the two 1M resisters, i changed them. Can you buy new carbon resisters or are...
