T-368 Modifications by The TimTron, Tim Smith, WA1HLR Contains detailed specs on the speech amp, modulators and improvement mods for this rig. "With the stock iron, there was a noticeable improvement in the low end response. Further improvement can only be obtained by installing a different modulation transformer. Space is limited. However, there is one type that appears to be made to order, the famous RCA 5500-to 5500 Ohm (1:1 ratio) open frame broadcast type. There is JUST enough space to install it. However, two electrolytic caps (C17, C18) that were part of the carbonium microphonuim voltage circuit must be removed. R19 is also jumpered out of the circuit. The new mod transformer will drop right on the chassis like it was meant to be. " Case closed.
