Hi Wayne. Both are wood,tabletop and same tube lineup: 6d6,6c6,43,25z5. The 153 is bw/sw with a k55c ballast. the 194 is bw only with a k55b ballast. My problem is with the electrolytics. Both have unmarked rectangular paper multi-caps. The 153 has 7 wires;3 black, 4 brown. The 194 multi-cap has been changed at some point as it has 6 leads with only 5 connected and the leads have been taped at mid-wire connections. I am new to old radios and don't want to try to guess at these values. The 194 is listed in Steins Tabletop Vol.1, p-48. Thanks for your response. Spencer CS
