[QUOTE="Ampdog, post: 48107, member: 144"] One more thing - sorry to add bits-wise... (reminds me of my parents, Malmesbury. Father walking down to the grocery store; Mother shouting a series of last recalled items to him, even when he was already a block away ... The friendly neighbours had a joke about that ...) Er - sorry; nostalgia - The Quad II power transformer is underrated voltage-wise; in SA always keep the mains voltage adjuster at the highest tap (240V). The heaters are the problem; they can sit at 6,5 - 6,6V; not good. (The h.t can go to 360Vdc, which is not a problem. One can get a clean 18W from the amp at that with GZ34 rectifier.) [/QUOTE]
