I now have some UF5408 diodes, so will fit these. The 2k2 wire-ended 10watt resistors are quite long (about 1" + wire lead-outs, so fitting them might be a bit problematical, given that they will run at least warm. There isn't a lot of space between the mains Tx. and the rectifier valve base, besides which the primary circuit fuse-holder is fitted directly underneath the GZ34's socket . I still haven't found a Circuit diagram showing which, if any, of the suggested mods. were ever factory fitted, b.t.w.
