Default Re: Repairing a 14" Philips Tea-Chest

Nice job Mike. These receivers are incredibly ugly but I suppose after a dozen 'Tinnies' anything can look beautiful. On the plus side they are incredibly reliable and being Philips give a grand stable picture.
I have a similar model, like yours repaired around 30 odd years ago and then simply cast aside as more attractive receivers came along. Maybe I'll get it out sometime..
That partial heater short was an ongoing problem with Mullard tubes from the 12" MW31-74 series right up to the last ion trap tubes the AW43-80 a period of over eight years. Simple to cure but they never did. Leaning the cabinet back and tapping the tube neck will cure it for a very short period but it proves the point. I have never heard of a BY127ZX30..Oh dear, what a stinker. All the best, John.
PS Tea chest, I like that. The cabinet is even lined with tinfoil!
