I getting ready to build an amp and will be using all UTC LS iron if i build it stereo , if i build it as two mono amps will use a mix of UTC LS and Potted H series iron . I could also build stereo with the power supply on a separate chassis but the umbilical between the amp and power supply bugs the hell out of me .

Will be using a pair of UTC LS-39's as input transfomers and phase splitters , UTC LS-60A as output transfomer . Have a custom made UTC lS power transfomer in a LS -4 case and a LS- 94 choke and will need a 24" X 18" chassis to fit it all on .
Will be Using two 6J5GT's and two 300B's per channel . Was going to use the LS-58's as output transformer , until i acquired the LS-60 A's which will put the 300bs in a more linear portion of their curves .
Anyone want a pair of UTC LS-58s reasonably .
If i go to two mono amps will use two UTC H-84 power transfomers and matching chokes .
