I have a funny feeling of deja-vu here. On post #12 I bodged in a substitute of 5 0.1mfd X2 caps in parallel as i don't have a 0.47mfd cap to hand... I did notice they were quite warm after leaving the set running for a while. All other wax and black hunts caps have already been replaced in the set. I will find another substitute or even pop the original wax cap in for the craic. The U26 is glowing away nicely and the PL81 looks happy and like any other valve without a slight blue glow and no slightly glowing anode plates as observed earlier. The comment earlier about loud scan coils was a mistake - the whistle is emanating from the LOPT and can be heard from the other end of the garden. Did not see any cats in the neighbourhood either.
