Greetings to all, Some one put a very nice cross reference out for semiconductors used in Heath gear. Does anyone know of such a cross reference for transformers and/or other parts. I am trying to cross reference a 54-198 transformer. It is new in the original box. I just do not know what kit it went with. 73 de Lon W. Cottingham, K5JV 1110 Golden Bear Ln.
