Hi everyone , I need help . My 661 has HV insulation breakdown in the power transformer and I need a suitable 6v transformer that can stand working at 3KV for the CRT heater . Here in the UK most sources for things like that have all but dried up . Does anyone in the group have one spare they would part with or know of a reliable source for a replacement . I would prefer as local a source as possible but obviously I would get one from anywhere . Thanks in advance for any help with this . Brian Skilton (UK)
