Does anyone have a data sheet or any info. on this reg., so I can check the parameters? I have a Tatung video monitor (model: 27MDA) that the h/v shuts down after on about 5 min. The other circuits seem to remain active and the filaments stay lit. If I spray the reg. with coolant every few min.- stays on, but the heat sink does not get hot (weard huh). I've not worked with this #regulator before, so might be over-loading, or just going bad?
