Any one know how to wire the HT on Merren's 45? 5 lugs. Middle should be center tap. What are the voltages on the inner two and outer two? So what historically should the cosmetics be? Clapton/Block logo or is this to late with Drake and chassis mount repo selectors? Option for Micas are RS Arched Logo 250p maybe a Arched Logo 560p or Red Lemco 500p. Piher or Iskra.
