Cousin Billy-That orange 0,1uF in series connected with 7,5 0hm power resistor forms output Zobel network which appear connected in parallel with amplifier output two terminals ,
-Those two 600 ohm power resistors are ground reference resistors for Circlotron OPS , and if they are not connected in proper way as is was originally from A-T manufacture your amp will make booom and fail !
-Further I think that those big Mundorf capacitors do not belong there ,
electrically maybe but physically don`t ,
- Personally I will never modified those great OTL amps in your way .Happy New Year and all the best !
