Hey
My Route 66 (s/n 10039) is equipped with a set of GTKT66-HP grade 5 tubes. The recomended center-tap voltage, according the Doctor's bias recommandations, should be app. 475 V for optimum. Mine reads app. 435 V (a bit under-biased I suppose). My problem is: Where do I locate the mentioned bias trim pot. I can only locate one trim pot which is on the circuit-board. Is this the one to use (I just want to 123% sure)...or have I missed a detail?? Note; my amp has green/white wires going to the center-tap (just a detail I guess...). Please help (Myles perhaps??) !
